Impact of Perceived Risk on Consumers Technology Acceptance in Online Grocery Adoption amid COVID-19 Pandemic

: E-commerce industry has witnessed a phenomenal growth globally due to the sudden spread of the COVID-19 pandemic and the advancement of mobile Internet technology, with fast adaption of online shopping technologies by the customers. Previously, online shopping was only available in a few product categories and to a select group of consumers. The COVID-19 guidelines related to safety, physical distancing, closure, lockdown, and other restrictions have insisted that consumers shop online. Because of e-commerce growth, the grocery (FMCG) industry is also equipped with advanced technologies such as the Internet of Things (IoT), cloud computing, and block chain technology. This paper analyzes the UTAUT2 model and its inﬂuence on perceived risk and consumer trust in online purchase intention of grocery categories of products among Indian customers. We tried to analyze the growth potential of new technologies in grocery retail and formulated the hypotheses. The results showed that the spread of COVID-19 pandemic had a signiﬁcant inﬂuence on the online shopping behavior of Indian customers. The outcome of the study partly assists businesses in understanding the impact of the factors of consumer adaption of technology, perceived risk associated with online transaction, consumer trust in online technologies and consumer online purchase intention of grocery products. To promote e-commerce in India, the current study suggests that marketers should try to develop consumer trust and lowering the perceived risk associated with online shopping. Some management implications and future area of study based on empirical ﬁndings are also highlighted in the present research work.


Introduction
E-commerce industry has witnessed a phenomenal growth due to the rapid advancement of mobile internet technology and technophile customers. Many traditional industries, such as FMCGs, are attempting to capitalize on the market opportunities presented by transformation and up gradation. Previously, online shopping was only available in a few product categories and to a select group of consumers. The volume of global online commerce has increased significantly, owing to the recent COVID-19 crisis [1,2], which has accelerated the growth of e-commerce. Because of e-commerce growth, the grocery (FMCG) industry is also equipped with advanced technologies such as the Internet of Things (IoT), cloud computing, and blockchain technology. The devastating effects of the COVID-19 pandemic on the global economy as a result of lockdown, physical facility closures, perceived risks, and personal safety concerns [3] are some of the influencing factors building consumer intention to purchase even grocery products online. In recent years, a large number of e-commerce firms have entered the FMCG sector in the hope of creating value and sharing market benefits. Online grocery shopping is becoming an increasingly important part of life for customers all over the world, and it has fundamentally altered the way people shop for groceries. Because of the omnipresence of technology and the consumer convenience, online shopping has grown significantly in terms of volume as well as use. The COVID-19 pandemic has motivated consumers to accept technologies and purchase grocery products online. Newer technologies and business models, as well as big data/predictive analytics, indicate that the shopping experience is about to take a quantum leap into an unknown shopping realm [4]. Many studies on customer behavior [5,6], new business models [7,8], retailing technologies such as virtual reality [7,8], and changes in retailing reality in certain shops [7] indicate the relevance of new technology in retailing. Changes in the internet's rapid expansion are now influencing the retail-shopping model, with the use of new technology to enhance the whole consumer shopping process, placing pressure on traditional company strategies to adapt. In the grocery industry, there are three sorts of business models. These include "brick and mortar" used in conventional retail chains, "pure-play" used only by online merchants [9], and "bricks and clicks" used by retailer traders online and offline through their offline chain shop (known as multichannel retailing) [10].
The global spread of the COVID-19 epidemic has changed people's shopping habits and perceptions of e-commerce. The country's enforced lockdown regulations, as well as customers' rising reluctance to venture outside and buy for necessities, have pushed it into e-commerce. Consumers have shifted their purchasing habits away from shops, supermarkets, and shopping malls and toward online portals for products ranging from necessities to branded goods. Indeed, the COVID-19 emergency declared in March 2020 gave a strong boost to food hoarding [5,7] and online shopping for food products, with an increase in the number of customers buying foods online to comply with the rules (particularly social distancing)-and simply to ensure they get the food they want instead of facing empty shelves. The COVID-19 pandemic has posed many challenges before business houses and consumers also. Consumer adaption of technology in exploring online shopping of grocery items has motivated them to choose this topic as subject of research. Many studies have shown that, despite technological advancement, its acceptance and influence in building intention to purchase grocery products online is limited. Two important factors that influence low acceptance of online e-commerce platforms are perceived risk and consumer trust in online transactions. As a result, two fundamental questions arise: (a) what factors influence consumer acceptance of technologies for online grocery shopping? and (b) whether consumer trust and perceived risk associated with online platforms mediate the relationship between consumer acceptance of technology for online grocery purchase intention.

Consumer Trust and Online Grocery Purchase Intention
Accepting online shopping technologies and facilitating any transactions requires trust. Because it is a virtual transaction, trust is more important in E-commerce than in offline transactions. Consumer trust is critical for increasing consumer acceptance of new technology in online shopping and assisting in the process of e-commerce expansion in various retail product categories [11,12]. Trust is positively influenced by technical security features, simplicity of navigation, information display method, and an individual's verification. Trust is a key component in developing buy intentions and establishing longterm consumer connections for repeat purchases and loyalty. Trust is positively influenced by technical security features, simplicity of navigation, information display method, and an individual's verification. Because cognitive and emotional trust influence consumer acceptance of the ideals communicated, trust also has a hierarchical influence on perceived value [13]. E-retailers should consider that they could achieve greater success if they assure customers that their personal information will be safe, and they can increase their trust by providing facilities that provide more secure transactions when they do online purchasing. According to [14], trust is an evaluation of one's relationships with another person who will carry out certain transactions in line with the expectations of people who carry out transactions in an unpredictable environment. This trust does not emerge quickly; it must be nurtured and continuously proven. These considerations lead to the following hypothesis: Hypothesis 1. Consumers acceptance of technology has a positive impact on online grocery purchase intention.

Hypothesis 2.
Consumers trust positively influence the online grocery purchase intention.

Perceived Risk and Online Grocery Purchase Intention
According to available research, consumers continue to believe that using the Internet for purchasing is risky [15,16]. Furthermore, whether or not a person makes an online purchase, these perceptions can have a significant and inverse relationship with attitudes and intentions [17,18]. Consumers' propensity to order groceries online was observed to be very low. The spread of the COVID-19 pandemic, on the other hand, has compelled many customers to shop online. Despite technological advancements and the exponential growth of internet services in business facilitation and retail modeling, organized retailing only accounts for 19% of the retail market [17][18][19]. This means that some factors are impeding the growth of online marketing and online transactions in such product categories. One of them is the customer's perception of risk associated with online purchase. Retailers must comprehend the issues associated with perceived risks and devise solutions. The fear of the unknown is the main factor that prevents customers from purchasing via the Internet. Because of a number of problematic causes and concerns, some people have negative impressions about e-commerce purchasing behaviors. The fear of the unknown is the main reason that prevents people from purchasing through the Internet. Some people have bad impressions about e-commerce purchasing activities owing to a variety of problematic causes and worries. While both security and privacy are essential, clients are more concerned about security than privacy. If online clients' actual purchase experiences diverge from their purchasing intentions, they will perceive a higher level of risk [19]. According to Cox and Rich [20], perceived risk is determined by the subjective ambiguity of the consequences. Consumers will have multiple buying goals or expected results of purchasing items or services for each purchase choice. Several forms of perceived risk have been widely employed in past study, and it has been discovered that consumers appear to be cautious while purchasing online [20]. Pentz et al. [21] explored the consumer adaption of digital technologies in online shopping and found significant different in dimension of perceived risk in online shopping among experience and inexperienced online shoppers for different categories of products. Pham and Awan [22] found COVID-19 played a moderating role in consumer utility awareness, which encouraged shoppers to shop online. However, society's affection may be a factor in consumers' reluctance to shop online. Meanwhile, contrary to previous research, awareness of the COVID-19 pandemic and marketing policies have no significant impact on online shopping during the COVID-19 pandemic. According to the previous research findings, perceived risk is an important factor in explaining consumer behavior. As previously stated, consumer purchase intention and purchase behavior can be viewed as an example of risk-taking, based on the fact that any action taken by consumers will have consequences that they cannot predict with any degree of certainty, and at least some of which are likely to be unpleasant If perceived risk is powerful in explaining customer behavior, consumers' reluctance to purchase online could be a direct result of perceived risk, particularly in emerging markets. Based on the preceding discussion, the following hypothesis is proposed: Hypothesis 3. Consumers perceived risk positively influence the online grocery purchase intention.

Consumer Technology Acceptance, Perceived Risk, Trust and Online Grocery Purchase Intention
The relationship between consumer trust, perceived risk, consumer acceptance of technology in online purchase of FMCG product has been extensively searched in many studies. A review of the literature on some of the factors of consumer acceptance of online grocery shopping is presented below. It has been demonstrated that social influence has a major impact on human behavior in general and technology adoption (TA) in particular. Several studies have been done to investigate the function of social impact in the adaption of online shopping technologies, and it has been shown that social identity and group norm have substantial effects on consumer involvement. Positive social influence has been found to enhance the link between beliefs and attitudes regarding online buying, as well as the relationship between attitude and shopping intention. In terms of consumer online shopping behavior, authors like Pascual-Miguel et al. [23] and Ingham et al. [24] indicated that social influence may be handled through the impact of individuals like family, friends, and coworkers to whom the customer could seek knowledge or social approbation to utilise online shopping. The previous work related to many online buying research like Zhou, T. [25], Lorenz et al. [26]. Matthew et al. [27] (have confirmed the impact of social influence on consumer intention to use online shopping. Venkatesh et al. [28] define effort expectancy as the amount of comfort associated with the use of any system. This means that effort expectation relates to the amount of work required utilising the system, regardless of how simple or complex it is. Users may readily embrace and utilise user-friendly technologies. As a result, effort expectation is expected to have a significant influence on buyers' intentions to use online purchasing. Ingham et al. [24] experimentally revealed a strong relationship between perceived ease of use (as a comparable factor to effort expectation) and customer attitudes about online purchasing. Pascual-Miguel et al. [23] recently confirmed that females' desire to use online shopping is significantly predicted by the function of effort expectation, while this link is more likely to disappear for male groups. Mandilas et al. [29] found a substantial direct link between perceived ease of use and customer intent to utilise online purchasing.
The extent/degree to which an individual feels that adopting the system would help him/her achieve increases in work performance is referred to as performance expectation [28,30]. This element, like perceived usefulness from TAM, is acknowledged as a critical component in shaping an individual's attitude toward utilizing any technology [31,32]. According to [33], the degree to which a person believes that using a certain biometric technology will fulfil the organization's security access demands in a specific region is referred to as performance expectation. Indeed, either performance expectation or an equivalent concept captures the cognitive gains expected while utilising a new technology. Importantly, such benefits have been widely seen to have a substantial effect on people's perceptions and desire to embrace various types of apps [34][35][36]. Customers' intentions to utilize online shopping were also found to be significantly predicted by the function of perceived usefulness, a concept related to performance expectation. Performance expectation has been found to specifically, substantially, and favorably impact one's behavioral intention to adopt and use an IT system [36,37]. Facilitating conditions refer to a person's belief that organizational and technological infrastructure exist to facilitate system utilization [28]. It refers to external elements such as infrastructure and resources that influence the desire to buy food online in the context of this study. Hedonic motivation refers to the effect of a person's pleasure and pain receptors on their desire to go towards a goal or away from a hazard. The capacity of the web and e-commerce platforms to give hedonic, non-functional value to online consuming experiences is widely known, as is the importance that customers place on hedonic benefits. Martnez-López [38] developed a perceptual behavior theory (PBT) and applied the technology acceptance model (TAM) to explore the influence of trust, perceived danger, perceived utility and perceived ease of use on purchase intention.
The relationship between consumer trust, perceived risk, consumer acceptance of technology in online purchase of FMCG product has been extensively searched in many researchers. Bianchi and Andrews [39] examined the influence of trust and risk on the purchase behavior of Latin American consumers. Perceived risk and trust variables, according to the data, had a favorable effect on the desire to continue shopping online. Consumer attitude influences their propensity to buy online, and perceived danger has an inverse connection with attitude. Juaneda-Ayensa et al. [40] examined the major determinants of technology adoption and use, as well as their influence on buy intent, which underlies multi-channel consumer behavior. Nagy and Noémi [41] investigated how consumers adopt and use Artificial Intelligence (AI)-powered online shopping. The study looks at consumer trust and acceptance of AI in online retail. An online survey was conducted in Hungary to create a database of 439 respondents for this study. Trust was discovered to be one of the most important factors influencing consumer attitudes toward AI. The other key factor in attitudes and behavioral intention was discovered to be perceived usefulness, which was found to be more important than perceived ease of use. According to a similar study by [42], consumers still have the choice whether to use new technology, such as shopping online in an AI web shop, or not. Arguments leads to the following hypothesis (see Figure 1).

Hypothesis 4.
Consumer trust mediates the relationship between consumer adaption of technology and online grocery purchase intention.

Hypothesis 5.
Consumer perceived risk mediates the relationship between consumer adaption of technology and online grocery purchase intention. applied the technology acceptance model (TAM) to explore the influence of trust, perceived danger, perceived utility and perceived ease of use on purchase intention.

To analyze the role of consumer trust and the perceived risk associated with online purchasing of grocery items and the relationship between consumer acceptance of online technology and purchasing intentions for grocery items.
The present study employed a descriptive research design. Data for the current study were gathered from Indian consumers via an online survey created on Google forms and administered over a two-month period from February-March 2021. Consumers were asked to participate in the study through email and by posting invitations on well-known websites using snowball sampling. Snowball sampling is a technique in which research participants recruit additional participants for a test or study. It is utilized when finding suitable participants is difficult. This sampling approach entails primary data sources recommending additional prospective primary data sources for use in the research. In the current study, a questionnaire was originally distributed to possible respondents, who were requested to complete it and forward it to a known one. There were three sections to the survey questionnaire. The first section included questions about respondents' demographic profiles and motivations for purchasing online grocery items. The second part of the questionnaire contains attributes related to variables influencing consumer adaptation of technology in online grocery shopping based on previous work of [30,43]. The third section of the questionnaire focuses on consumers' perceived risk and level of trust in online shopping technologies. Previous work of [39,44] identified measurement variables for measuring consumer trust and perceived risk. Based on the previous work of [45], the fourth part of the questionnaire consists of items related to consumer online grocery purchase intention was developed.
Respondents were asked to express their level of agreement with key traits on a five-point Likert scale (where five designated as strongly agree and one designated as strongly disagree). A panel of three marketing academics reviewed the first questionnaire, assessing its content's validity, the clarity of its item meaning, and the associated linkages of discovered variables with the research objectives. The questionnaire was tested for reliability with 45 respondents, representing 10% of the overall sample size, who were thought to be typical of the research population. Cronbach's alpha was found to be 0.946 for the full survey, indicating that the questionnaire had an acceptable level of reliability. Researchers received 479 responses, and after editing, 443 were found to be suitable for use in this study, excluding 36 responses that were incomplete or insincerely answered. The collected data was systematically organized, tabulated, and analyzed using SPSS 22.

Results
The information presented in Table 1 depicts the demographic characteristics of respondents. It is observed that sample is the combination of younger aged respondents as 19% respondents fall in the age below 20 years. A total of 33.4% respondents were in the age group of 21-30 years, 26% were in the age group of 31-40 years, 11.3% were in the age group of 41-50 years, and the remaining 10.4% were in the age above 50 years. Males dominate the sample with 70.4%. Regarding education, 25.1% of respondents were less than graduate, 38.6% were graduate, and 21% were postgraduate. Remaining 15.3% of respondents had professional degrees. Students dominate the sample with 43.6%. Salaried (32.1%) and business owners (12.9%) followed it. Homemakers represented by 4.1% of the sample. 57.1% of respondents were unmarried while 42.9% were married. Based on monthly income, 33% were having monthly income in the range of INR 25,001-50,000. It was followed by INR 50,001-75,000 (27.8%). Only 5.4% were having monthly income more than INR 100,000. Information presented in the Table 2 indicates descriptive statistics for various factors related to consumer acceptance of technology for online grocery shopping. Five important constructs were identified based on unified theory of acceptance and use of technology proposed by Vanketesh et al. [30]. Results indicate that factor 'Hedonic Motivation' has the highest mean (3.90). It was followed by 'Facilitating Conditions' (Mean = 3.86) and 'Social Influence' (Mean = 3.84). Factor 'Effort Expectancy' secured the lowest mean value (3.77). Item 'I feel comfortable in using online system for grocery purchase' had the highest mean value (4.01). Item 'It is easy for me to become skillful at online grocery purchase platform' had the lowest mean value (3.65). The reliability of factors was found within the appropriate range (0.679 to 0.765). Risk perception and consumer trust in online shopping technology are two important contrasting components affecting consumers' adoption of online grocery shopping. Data presented in Table 3 indicates that consumer perceived risk had mean value of 3.85 and standard deviation of 0.607. Item 'I feel my disclosed personal information while online grocery purchase are safe' secured the highest mean of 3.92 with standard deviation 0.964. Consumer trust factor had mean value of 3.62 and standard deviation of 0.638. Item 'Winning consumer trust in ecommerce is the wisdom of online grocery service providers' had the highest mean (3.71).

3.65 0.713 Data presented in Table 4 indicates descriptive statistics for various items of consumer intention to purchase grocery online. The reliability and mean of online grocery purchase intention were 0.607 and 4.13 respectively. Item 'I hope that online grocery will a compulsion for every e-commerce platform in future' had the highest mean (4.22).

Regression Analysis
In the present research model, the relationship between factors influencing consumer acceptance of technology for online grocery purchase, perceived risk associated with online grocery shopping, consumer trust and intention to purchase grocery online was tested using regression analysis. In examining the concept 'consumer acceptance of technology for online grocery purchase', the combined factor mean (social influence, effort expectancy, performance expectancy, facilitating condition, uses expectancy, and hedonic motivation) was utilized. A similar combined mean of six measurement variables was calculated to examine the constructs of 'customer trust' and 'perceived risk'. Four measurement variables were calculated in relation to consumer online grocery purchase intention. Regression analysis was performed in four steps using SPSS software. In the first step, a regression analysis was performed to determine the direct impact of the consumer acceptance of the technology component of online grocery purchasing. In the next step, the impact of factors of consumer acceptance of technology on consumers' perceived risk and consumer trust was determined. Finally, the impact of consumer perceived risk and consumer trust on consumer online grocery purchase intention was calculated. Results are presented in the Table 5 and Figure 2.

In next step, the impact of factors of consumer acceptance of technology on consum perceived risk and consumer trust was determined. Finally, the impact of consum perceived risk and consumer trust on consumer online grocery purchase intention w calculated. Results are presented in the Table 5 and Figure 2.  The information presented in the Table 5 and Figure 2 indicates that the direct ef of consumers acceptance of technology on online grocery purchase was found signific (F = 625.401, t = 25.008, p = 0.000) and contributed 58.6% (R 2 = 0.586) to online purch The information presented in the Table 5 and Figure 2 indicates that the direct effect of consumers acceptance of technology on online grocery purchase was found significant (F = 625.401, t = 25.008, p = 0.000) and contributed 58.6% (R 2 = 0.586) to online purchase intention. It has significant effect on online purchase intention of grocery products. Hence, the research hypothesis is accepted indicating the consumer acceptance of technology has significant effect on consumers' online grocery purchase intention.

Consumer
Further, the indirect impact of consumer acceptance of technology on online grocery purchase intention via consumer perceived risk and consumer trust was calculated. The results indicated that the impact of consumer acceptance of technology on consumer perceived risk was found as significant (F = 515.215, t = 22.696, p = 0.000) and contributed 53.9% (R 2 = 0.539) to online grocery purchase intention. The results revealed that the beta value for factor of consumer acceptance of technology is 0.734 and it has significant effect on consumer perceived risk associated with online shopping. Hence, the research hypothesis is accepted indicating that impact of factors of consumer adaption of technology on consumer perceived risk was fond significant. The impact of factors of consumer acceptance of technology for purchasing grocery online on consumer trust was found significant (F = 483.375, t = 21.986, p = 0.000) and contributed 52.3% (R 2 = 0.523) to consumer trust. The results revealed that the beta value for factors of consumer adaption of technology is 0.723 and it has significant effect on consumer trust. Hence, the research hypothesis is accepted indicating the consumer acceptance of technology has significant effect on consumers' trust.
Further the impact of consumer risk perception on online grocery purchase intention was tested and found significant (F = 331.090, t = 27.871, p = 0.000) and contributed 42.9% (R 2 = 0.429) to consumer online purchase intention. The results revealed that the beta values consumer trust is 0.655 and it has significant effect on consumer online purchase intention. Hence, the research hypothesis is accepted indicating the consumer perceived risk has significantly influence on consumer online grocery purchase intention. The impact of consumer trust on online grocery purchase intention was found significant (F = 305.030, t = 17.465, p = 0.000) and contributed 40.9% (R 2 = 0.409) to consumer purchase intention. The results revealed that the beta value of consumer opinion is 0.639 and it has significant effect on consumer grocery online purchase intention. Hence, the research hypothesis is accepted indicating the consumer trust has significant effect on consumers' online grocery purchase intention. Note that, the normal probability test was carried out with the help of SPSS software for assessing whether a data set is approximately normally distributed. SPSS automatically gives a normal probability plot, specifically a P-P plot. Normally a P-P plot is conducted to compare the observed cumulative distribution function (CDF) of the standardized residual to the expected CDF of the normal distribution. An inspection from the regression standardized residual (Figure 3) was also found to be normally distributed whereby the observed and expected values were found along the line, without any significant departures from it.

Mediation Analysis
A mediator variable describes how or why a relationship between an independent variable and its dependent variable is observed. Mediators are variables that increase the intensity of the relationship between a dependent and an independent variable. The relationship between independent and dependent variables is very weak in the absence of a mediating variable. They can be qualitative or quantitative variables that influence the direction and strength of a relationship, resulting in an interaction effect [32]. In general, mediation can occur if the following conditions are met: (1) the independent variable has a significant influence on the mediator; (2) the independent variable has a significant influence on the dependent variable in the absence of the mediator; (3) the mediator has a significant unique effect on the dependent variable; and (4) the independent variable's influence on the dependent variable and dependent variable. Such considerations can be used to determine whether or not mediation is taking place informally.

Consumer Perceived Risk and Consumer Online Grocery Purchase Intention
Tables 6 and 7 present the findings of the Sobel, Aroian, and Goodman tests, which were used to analyse the effect of a mediating variable (consumer perceive risk) of a given independent variable (consumer acceptance of technology) on a given dependent variable (consumer online purchase intention). The Sobel test revealed that p-values are less than 0.05 assuming a two-tailed z-test greater than 1.96, implying that the research hypothesis is accepted and concluded that customer perceived risk mediates the relationship between consumers' acceptance of technology and their intention to purchase groceries online.

Consumer Trust and Consumer Online Grocery Purchase Intention
The data in Tables 8 and 9 show the results of the Sobel test, Aroian test, and Goodman test, which were used to assess the effect of a mediating variable (consumer trust in online technologies) of a given independent variable (consumer adoption of technology) on a given dependent variable (online purchase intention). The Sobel test revealed that p-values are less than 0.05 assuming a two-tailed z-test greater than 1.96, implying that the research hypothesis is accepted and concluded that customer trust in online technologies mediates the relationship between consumer technology adaptation and consumer online purchase intention of grocery products.

Discussion
The COVID-19 pandemic has brought phenomenal change in business operation across the world and India cannot be an exception. This study contributes a different perspective, considering how consumer acceptance of technology for online grocery shopping influences consumer trust and reduces the risk of online grocery purchase intention in the Indian context. The findings support that hedonic motivation of consumer and facilitating condition highly influences customers in adapting online shopping technology for purchase of grocery products, and that consumer trust and perceived risk plays as mediating role in the relationship between consumer adaption of technology and online purchase intention of grocery products. The study is in support of previous research that has applied trust as a moderator element to measure its influence on online shopping decisions [46]. Hence, the contribution of this work is the consideration of consumers perceived risk and trust as mediating variable in the relationship between consumer adaption of technology and online grocery purchase intention amid COVID-19 pandemic. The UTAUT model is commonly used to analyze the acceptance of technology. In this research, the UTAUT model is tested on online grocery purchasing.
However, the result showed that hedonic motivation, facilitating conditions and social influence are significant factors in acceptance of online grocery technology. As consumers can see a variety of options, easily compare prices and offers, conveniently add or remove products from a cart and get free home deliveries with discounts, online grocery shopping using smartphone and websites are creating a feeling of excitement and fun. Moreover, modern Indian consumers are well equipped with smartphones, internet connections, which is timely, especially amid COVID-19 lockdown and curfews. These facilitating conditions are also motivating customers to use online grocery platforms for safe and contactless shopping experiences. The role of family members, friends, peers and acquaintances are significant in the acceptance of new technology. These social factors also motivate customers to accept online grocery shopping. Word of mouth communication is commonly used among family, friends and co-workers in the Indian society. Therefore, information on good deals is easily shared. Confidence levels will increase on the application if it is often mentioned in their daily conservation [47].
The impact of perceived risk and customer trust is another significant contribution of the study. Traditionally, consumers feel that shopping groceries online is much tedious if compares to shop ordinary stuff. Besides the low level of awareness, they are skeptical in using the online platforms for grocery purchase. However, amid COVID-19 pandemic, consumers are restricted to shop physically. In addition, consumers are also not interested in going to crowded physical shopping centers. The COVID-19 guidelines related to safety, physical distancing, closure, lockdown and other restrictions have influenced consumers to shop online. The findings revealed that the COVID-19 outbreak had a major impact on Indian customers' online shopping behavior. As a result, the research objective of this article has been met, and it helps businesses understand the impact of factors such as consumer technology adaptation, perceived risk associated with online transactions, consumer trust in online technologies, and consumer online purchase intention of grocery products.

Implications and Conclusions
Based on the findings, the emergence of the pandemic brought changes in consumer perceptions towards contactless shopping. Because of the importance and variety of hedonic motivations in online consumption experiences, company marketing strategists must pay close attention to them when deciding on website design and configuring online media strategies; this is especially important in the current context of social media. Even in online consumption processes that are heavily geared toward achieving instrumental goals. Online grocery marketing firms must continue to promote marketing strategies that stimulate consumer shopping needs by providing more purchasing options, particularly more policies that help customers gain trust in the online system and develop consumer trust in the contactless transaction system. True to reality, hedonic incentive, facilitating conditions, and social influence are all major elements influencing consumer purchasing decisions in India. Before making a purchase, people often seek the advice and opinions of family members or former purchasers. It can be seen that the information India consumers receive from others, whether through any form and means, has a significant influence on the buying decision of them. Perceived risk and customer trust are other important areas for online shopping platforms. The impact of COVID-19 will be apparent for coming months. Online grocery shopping platforms must realize the fact the modern consumers are more concerned about perceived risk and trust associated with technology acceptance. As the number of online frauds and concerns toward privacy and safety have increased, online platforms must explore ways to gain customer confidence and trust. In order to reduce consumer perceived risk and gain their trust, these platforms must focus on their efficient and safe deliveries, clearly demonstrate the values and quality of the product, utilize a user-friendly interface to avoid customer confusion and reduce effort, conduct promotional campaigns to attract potential consumers and provide appropriate information. Referral programs and encouraging satisfied customers to write positive reviews could be the other possible strategies to attract customers and gain their trust. Online grocery shopping platforms need to be more professional, change faster, grasp technology trends to better meet the needs of consumers not only amid pandemic but also in the post pandemic period also as in a long run online shopping trend is expected to grow faster. In particular, the process of return, exchange or refund should also be focused and designed in a simple way to enhance the experience of online shopping for consumers.

Limitations and Future Research
In the present research, the existence of an issue that has not been fully exploited is inevitable, and this study is no exception. The first is that the study's mediating variable centers only around the looming concern of 2020, which is the COVID-19 pandemic. Second, while age and gender have a big influence on online purchasing decisions, this paper focuses on risk and consumer trust rather than these aspects. Finally, the survey's scope and small sample size limit its applicability in the Indian context.
To avoid this issue in the future, studies should collect data from a variety of sources. The relevance of the finding can be increased by drawing from a bigger group that spans demographics and cultures. The survey in this study is limited to one country, India. This enables follow-up studies to broaden surveys across countries in order to analyze differences in online purchase intentions across economies and cultures.
