Local innovations regarding plant-derived spice and flavorant formulations and preparation techniques are mostly recorded nowhere and usually passed on generationally through word of mouth. This study aimed to inventory the utilization of plants and perceptions of novel indigenous food spicing and flavoring among the Vhavenḓa people in South Africa. This study adopted face-to-face interviews with 360 participants using semi-structured questionnaires. This study investigated a total of twenty-seven plant species used to spice-flavor novel indigenous Venḓa foods, including mukokoroshi meat stew, mopane worms, vegetables, homemade achar, eggs, samp meal, potatoes, and sweet potatoes. Based on the perceptions by participants from different age groups, indigenous foods spicing and favoring significantly improved food taste and nutrition (43.1%), providing medicinal benefits (33.3%) and cultural identity (23.6%). No study had ever reported the uses of Lannea edulis (Sond.) Engl., Mangifera indica L., Centella asiatica (L.) Urb., Warburgia salutaris (G.Bertol.) Chiov., Plectranthus fruticosus L′Hér., Hibiscus sabdariffa subsp. Cannabinus L., Oxalis semiloba subsp. semiloba, and Ziziphus mucronata subsp. mucronata and their preparational techniques for novel indigenous foods, spicing, and flavoring before, in South Africa, or elsewhere. The current study provided insights about spice and flavoring plants that could be used to develop alternative marketable commercial products. The findings of this study provide necessary baseline information for evaluating and profiling the nutritional content of spice-making and flavoring plants in the Vhembe Region. Full article

Investigations into crispy and crunchy in American English have demonstrated that these synonymic taste words have differing effects on perceived taste depending on association. To test the generalizability of these findings, category fluency tasks were used to elicit foods and beverages more and less associated with several pairs of synonymic taste words. Next, taste tests were conducted using synonymic taste words and some of their more and less associated products as stimuli. The results showed that more associated taste words have a marginally significant, positive effect on taste ratings, with significant interaction effects for certain products resulting in lower taste ratings. This study confirms that synonymic taste words beyond crispy and crunchy can alter perceived taste in American consumers. Moreover, it demonstrates that the underlying mechanisms are complex and, in addition to association, depend on the particular food or beverage as well as further factors. Full article

In food research and development, fully capturing consumer preferences is crucial for enhancing ingredient selection and formulation. However, many decisions still rely heavily on expert judgment. To address this, we propose a semantic analysis framework that combines heterogeneous information network representation learning and lexicon-based sentiment analysis to uncover relationships between ingredients and consumer word-of-mouth. We apply our approach to 1062 breakfast products and 58,206 reviews from Amazon, extracting taste- and ingredient-related sentiment while excluding non-formulation factors (e.g., price, packaging, logistics). Through embedding-based visualization, our product space groups items according to similar formulation characteristics, while the ingredient space reveals functional clusters among ingredients. We find that high-reputation products and their related ingredients form distinctive clusters in both spaces, often emphasizing natural, organic, and gluten-free attributes, whereas items containing synthetic additives appear more frequently in low-reputation regions. This framework offers a data-driven complement to traditional R&D methods, providing a perspective distinct from conventional approaches for product formulation and ingredient selection.

When considering the chronological order of product use, package design is mainly related to forming the anticipated UX, which predicts and imagines the experience gained from interacting with the product. However, in previous research, no method has been established for specifically evaluating the anticipated UX, and there is little knowledge about the relationship between packaging design and anticipated UX. This research aimed to examine a method to investigate the anticipated UX that users gain from packaging design in an exploratory and qualitative manner. We adopted the evaluation grid method, an interview and analysis technique that can clarify the evaluation structure that people have for the target of evaluation, and examined the structure of the design elements of the packaging and the appeal and sense of expectation that can be gained from them. We selected 20 products from each of two product groups for evaluation as examples: boxed flour confections and sunscreen. Ten people participated in the grid evaluation method survey for each product, and an evaluation structure diagram was created to summarize the results for each group of products. For flour confections packaging, the focus was on whether people could imagine what the taste would be like, and for sunscreen packaging, the focus was on concepts related to the performance and effectiveness of the sunscreen. These results show that it is possible to grasp the anticipated UX based on the user’s words using the evaluation grid method. The results of this research will contribute to establishing a method for examining anticipated UX and will be useful for achieving packaging design that enhances UX. In addition, the findings of the analysis cases presented in this research can be used to improve UX in the packaging of sweets and sunscreen. Full article

A certain level of culinary sustainability was automatically built into many ancient cuisines due to scarcity in food supplies and, hence, optimal use of the available resources with minimal waste. The concept of sustainability in the global food systems today is much more complex, where the planetary limits to population growth and availability of food resources are leading to tremendous stresses on the overall conditions of the planet including the climate. Still, lessons from world cuisines across space and time may serve as a guide towards a more sustainable plant-forward cuisine in the future. In this essay, we highlight how a focus on gastronomy, especially gastronomic heritage, can provide a framework for a more sustainable cuisine. We see gastronomy as much more than related to cooking and fine dining but also referring to a complex understanding of the word, involving taste, lifestyle, meal culture, commensality, traditional knowledge, craftmanship, and food making. The Mediterranean Diet, traditional Japanese cuisine, and ancient Roman practices are discussed as examples. Full article

Reading fluency depends on the typographic design. Letters can have different shapes that evoke different feelings in the reader and influence reading fluency. Previous studies that explored the link between typeface shape and taste and its impact on reading and readers’ attitudes mainly focused on shorter texts or individual words. In contrast, our study investigated how the taste (sweetness) attributed to the typeface is related to reading fluency and the pleasantness of the typeface during reading longer texts, and whether these relationships are the same in children and adult readers. We found that readers of both age groups perceived rounded letters as sweeter than angular letters. The perceived sweetness correlated positively with the pleasantness of the typeface and reading fluency. Younger readers showed a higher general rating of sweetness and a stronger relationship between the perceived sweetness and the pleasantness of the typeface than older, more experienced readers. This suggests that the sweeter and more pleasant the typeface is perceived to be, the faster it can be read. When fast processing of longer texts is required, we recommend the use of rounded typefaces with more organic shapes, including serif typefaces with some characteristics of old-style typefaces, rather than using angular, sans serif typefaces.

Online product reviews provide valuable insights on user experiences and product qualities. However, issues such as information overload and the limited utilization of review features persist, particularly in personalized rankings for popular items like movies. To address these challenges—information overload in online reviews, limited review feature utilization, and personalized decision-making for high-demand products like movies—we introduce a personalized online decision-making framework that integrates a sentiment model for product attributes with an enhanced hesitant fuzzy scoring function. This framework incorporates the concept of symmetry in sentiment analysis. It employs feature words, sentiment terms, and modifiers to assess user sentiments within a hesitant fuzzy setting, utilizing symmetrical relationships between positive and negative sentiments. The improved fuzzy score function efficiently quantifies sentiment values for product features by considering the symmetrical balance of user opinions. Additionally, review quality assessment incorporates both content and reviewer characteristics, resulting in final attribute evaluations. An attribute weighting system, tailored to diverse product types, further captures product specifics and user inclinations, leveraging symmetry to balance varying user preferences. Validation through multi-genre movie sorting demonstrates the method’s capacity to handle review data across varied products and user tastes, offering a robust tool for enhancing online decision quality, especially for high-demand items.

Food evaluation is a topic central to consumer research and food marketing. However, there is little consensus regarding how consumers combine sensory stimuli, product information, and visual impressions to shape their evaluation. Moreover, the bulk of research relies on studies based on questionnaires and declarative responses, raising questions about subliminal processes and their hierarchy in an evaluation process. To address this gap in the literature, we conducted a study with more than 400 participants in Morocco and Tunisia and investigated how factors such as flavor/taste, product information, and packaging design in a variety of olive oils influence visual attention and are reflected in willingness to pay (WTP). We implemented incentivization through an auction to reduce the hypothetical bias in stated WTP values. The results revealed that, compared to tasting the oils, the provision of cognitive information led to an increase in consumers’ WTP. However, a drastic increase in WTP occurred when the consumers were exposed to package designs, overshadowing the formerly dominant effects of product attributes. These findings support theories suggesting a visual perceptual processing advantage due to the picture superiority effect–a picture says a thousand words. Further, it underlines the importance of graphic design in food marketing. The findings have ramifications for food marketing, product development, and pricing strategies. Full article

The language of wine is richer and more complex if compared to that of other alcoholic beverages, including the tasting, production, history, and culture associated with it. The evolution of the language employed to define the quality and the characteristics of wine from the “òstrakon” of the Ancient Egyptians to the present is shown in the article. The symbolic aspects of wine, the communication of emotions, the wine sensory analysis, and the wine tasting are discussed. The glossaries which appeared in France, at the turn of the 18th and 19th centuries, are mentioned: they attest both the beginning of tasting, and the official recognition of the sensory evolution of wine. Moreover, some considerations are reported on some particular words employed to describe wines: vinous, aftertaste, and body. The language employed to evaluate wine is still evolving. It expresses the need and the desire to communicate and define the perceptions and the emotions derived by drinking wine. Finally, the pleasure of wine is not only a physical pleasure, but above all it is a pleasure of the brain, as well as, naturally, of the word. Full article

Claims used in the marketing of commercial baby foods are often misleading, and there are concerns that they exploit parental anxieties. We adapted a hierarchical consumer emotions model to explore the emotional themes used in the marketing of commercial baby foods sold in the UK market. A survey administered in three large UK supermarkets collected in-store data on commercial baby food characteristics and the marketing claims used on commercial baby food packaging. The keywords found in these claims were entered in N-Vivo and allocated to four preexisting emotional themes: contentment, happiness, love, and pride. The prevalence of each theme was compared by age suitability (4+, 6+, 9+, and 12+ months) and taste (sweet/savoury) profile. A total of 1666 marketing claims (median 5, IQR 3) and 1003 emotional keywords (median 3, IQR 3) were identified on the packaging of 341 commercial baby foods. Foods suitable for infants aged 6+ months displayed more claims (50%, p < 0.05) and emotional keywords (56%, p = 0.07). Savoury foods displayed more emotional keywords (63%, p < 0.001). The keywords “little”, “encourage”, “love(ly)”, and “tiny” were the most frequently used words under the theme of love (36% total contribution). The emotional connotations of the keywords under the theme “love” are extensively used in the marketing claims on commercial baby food packaging. These might exploit parental vulnerabilities and influence their purchasing of commercial baby foods. Full article

Rice is an important crop in the word, and fat is one of the main important nutrient components of rice. The lipid content and fatty acid composition of grains significantly influences the quality of rice. In this study, 94 homozygous recombination inbred lines (RILs) were developed and the crude fat content of them displayed a normal distribution ranging from 0.44% to 2.62%. Based on their taste quality, a positive association between fat content and eating quality was revealed. Then, two lines (FH and FL) were selected with similar agronomic characteristics and different lipid content and taste quality for RNA sequencing analysis, and a total of 619 differentiable expressed genes were detected, primarily enriched in metabolic pathways such as starch and sucrose metabolism, fatty acid metabolism, and amino acid metabolism. The expression of two genes related to fatty acid synthesis and elongation was significantly up-regulated, while the expression of three genes related to fatty acid degradation was significantly down-regulated in FH grains. By using liquid chromatography, the relative levels of palmitic acid and oleic acid were discovered significantly higher in FH grains. Additionally, the comparative genomic analysis was conducted to visualize genomic differences of five genes. Ultimately, two genes (Os07g0417200 and Os12g0102100) were selected to be the key gene to affect the lipid metabolism, especially for the synthesis of unsaturated fatty acids, significantly changing the eating quality of rice. These results provide a theoretical basis for improving the taste quality of rice. Full article

Chefs often say, “You eat with your eyes first.” This means that, while taste, smell, and vision are distinct senses, visual stimuli generate expectations through learned associations, and these expectations exert cognitive top–down influences that can and sometimes do alter assessments of taste and flavour. This study investigates the intangible values associated with the visual assessment of high-end pastry cakes among individuals from diverse food cultures. Using word association, the study explored the emotions, sensations, and impressions evoked by the visual representation of five high-end pastry cakes. Thematic content analysis was conducted to interpret and group the evoked words into dimensions. Across all cultures, “Organoleptic properties” emerged as the most highly rated dimension, aligning with expectations for food product visual assessments. Full article

The research on tourism is constant and unending; food and wine tourism research still represents a small part inside this wider field. Wine tourism and events are critical for sustainable development of rural areas. In this context, the emotional bond between the wine tourists the regions and the producers that they visit is created, not just through the wine as a product, but also through a set of hedonic features that are present in the visit and tasting experience. To reach the research objectives, a quantitative methodology was chosen. For this research a questionnaire was used and completed by wine cellar visitors and distributed to wine tourism facilities. An online questionnaire was applied in wine and wine tourism social network groups. To test the hypothesis, a structural equation modelling (SEM) was used has well as an importance–performance matrix analysis (IPMA) was also used for further exploration of the results. Results reveal that brand love and wine involvement are positively related to emotional satisfaction, evaluative satisfaction, and word-of-mouth (WOM) intention. Regarding the two dimensions of satisfaction (emotional and evaluative), only the second revealed a direct and indirect positive effect on WOM. From an interdisciplinary point of view, this paper presents insights for niche marketing (i.e., wine tourism, segmentation and brand management) and for local and sustainable development. Lastly, the research limitations and suggestions for future research are presented. Full article

Geographical indications (GI) are designated by a member’s region or regions within a designated area when the particular quality, reputation, or other characteristics of a product are related solely to its geographical origin and manufacturing process. Manufacturing methods are carried out according to an established Code of Good Practices. The aim of the study was to offer an overview of the current status of the literature related to geographical indications in Romania. A comprehensive and systematic literature review was conducted, and the search process was carried out using keywords such as ‘Romanian geographical indications’ and ‘Romanian food labels.’ These specific words must be found in the title, in the abstract of the papers, and also in the keywords section. Agricultural and food products with geographical indications (including wine and spirits) are included in the research. Products and food not related to the agricultural environment, along with services, were not included. It was discovered that, in order to improve the situation concerning geographical indications in Romania and raise consumers awareness, it would be necessary to introduce new national certification that could be more accessible to both producers and consumers, and that would promote regional taste and encourage the preservation of culinary traditions.

In addition to the taste receptors corresponding to the six basic taste qualities—sweet, salty, sour, bitter, umami, and fatty—another type of taste receptor, calcium-sensing receptor (CaSR), is found in taste-bud cells. CaSR is called the ‘kokumi’ receptor because its agonists increase sweet, salty and umami tastes to induce ‘koku’, a Japanese word meaning the enhancement of flavor characters such as thickness, mouthfulness, and continuity. Koku is an important factor for enhancing food palatability. However, it is not well known whether other kokumi-receptors and substances exist. Here, we show that ornithine (L-ornithine but not D-ornithine) at low concentrations that do not elicit a taste of its own, enhances preferences to sweet, salty, umami, and fat taste solutions in mice. Increased preference to monosodium glutamate (MSG) was the most dominant effect. Antagonists of G-protein-coupled receptor family C group 6 subtype A (GPRC6A) abolished the additive effect of ornithine on MSG solutions. The additive effects of ornithine on taste stimuli are thought to occur in the oral cavity, and are not considered post-oral events because ornithine’s effects were confirmed in a brief-exposure test. Moreover, the additive effects of ornithine and the action of the antagonist were verified in electrophysiological taste nerve responses. Immunohistochemical analysis implied that GPRC6A was expressed in subsets of type II and type III taste cells of mouse circumvallate papillae. These results are in good agreement with those reported for taste modulation involving CaSR and its agonists. The present study suggests that ornithine is a kokumi substance and GPRC6A is a newly identified kokumi receptor. Full article
