In Australasian countries such as New Zealand, algae consumption is gaining in popularity within consumer markets. Beverages containing macro-algae, like kelp, and those containing micro-algae, such as spirulina, are considered novel products. While consumer preferences for algae-based products are well explored, less attention has been given to beverages, despite their importance for consumers, specifically those interested in health and well-being. The present study is dedicated to this research gap and investigates the key factors driving and hindering New Zealand consumers’ willingness to drink, pay a price premium, and spread word of mouth about micro-algae-based beverages, such as tea, smoothies, and cuppa soups. Theoretically, the present study is grounded in a seminal Australasian driver and barrier model of seaweed consumption. The current research design both confirms and extends the consumer behaviours previously examined. An online consumer study was distributed and collected via an opt-in panel provider, resulting in 437 responses. Consumers mirroring the NZ population in age, gender, and household income were the target sample, and descriptive statistics and a quantitative analysis via a partial least squares structural analysis served as the methodological foundation for the study. Food neophilia and involvement with algae were significant drivers for all three behavioural intentions investigated. Food neophobia was a significant inhibitor to the willingness to drink but not significantly related to the willingness to pay a price premium or spread word of mouth. Consumer perceptions of product attributes were a significant driver of New Zealand consumers’ willingness to spread word of mouth. The study provides best practice recommendations for marketers in Australasian beverage industries. In terms of its theoretical merit, two aspects stand out. Micro-algae beverages are an emerging beverage product category in Australasian markets, requiring wider exploration and complementary consumer research dedicated to algae-based food items. The focus on food neophobia and neophilia is original, as it helps to understand the barriers and drivers essential to beverages. In contrast to food items, beverages cannot hide novel ingredients such as micro-algae, making them simultaneously more appealing to food neophilic consumers and extremely challenging to food neophobic consumers.

Over the years, consumer awareness of proper, healthy eating has increased significantly, but the consumption of fruits and vegetables remains too low. Smoothie drinks offer a convenient way to supplement daily diets with servings of fruits and vegetables. These ready-to-eat beverages retain the nutritional benefits of the raw ingredients from which they are made. Furthermore, they cater to the growing demand for quick and nutritious meal options. To meet consumer expectations, current trends in the food market are shifting towards natural, high-quality products with minimal processing and extended shelf life. Food manufacturers are increasingly aiming to reduce or eliminate synthetic preservatives, replacing them with plant-based alternatives. Plant-based preservatives are particularly appealing to consumers, who often view them as natural and organic substitutes for conventional preservatives. Essential oils, known for their antibacterial and antifungal properties, are effective against the microorganisms and fungi present in fruit and vegetable smoothies. However, the strong taste and aroma of essential oils can be a significant drawback, as the concentrations needed for microbiological stability are often unpalatable to consumers. Encapsulation of essential oils in nanoemulsions offers a promising and effective solution to these challenges, allowing for their use in food production without compromising sensory qualities.

The pawpaw (Asimina triloba) is a tropical-tasting fruit from a tree indigenous to North America’s temperate climates. Pawpaw has a sweet, sour, and often bitter taste, which is a combination of banana and mango flavor. Fresh fruits are rarely available for retail purchase other than at farm sales or farmers’ markets. Frozen pulp is commercially available but supply is often limited due to increased wholesale demand. The purpose of this paper is to analyze seven years of entries from the Pawpaw Cookoff at the Ohio Pawpaw Festival using case study methodology to provide a basis from which to track trends, make recommendations, and discuss gastronomic opportunities of the pawpaw. Analysis of the data indicates that pawpaw is a versatile fruit that has been incorporated into a wide variety of beverages, savories, sauces, condiments, sweets, and desserts. Pawpaw pairs well with both alcoholic and non-alcoholic beverages, especially certain ales, sour beers, innovative cocktails with rum, coffee and tea drinks, and smoothies. Pawpaw is easily incorporated directly into salsas, dips, salad dressings, and frozen desserts that do not require cooking. In cooked savory dishes, sauces, and condiments, pawpaw should be added at the end of preparation. Pawpaw can be used in a wide range of baked and fried sweets and desserts. Full article

The effects of high-pressure processing (HPP) (450 MPa/600 MPa/3 min) on the carotenoid and vitamin E contents of smoothies made from strawberry, orange juice, banana and apple, and the same smoothies enriched with dietary fiber from discarded carrots were compared. The contents and bioaccessibilities of these compounds were also evaluated over the course of 28 days at 4 °C. The application of HPP in the formulations significantly increased the contents of β-cryptoxanthin, α-carotene and β-carotene and retained the contents of lutein, zeaxanthin and vitamin E compared to untreated samples. A decreasing trend in the content of each compound was observed with an increase in storage time. The application of HPP initially led to reductions in the bioaccessibility of individual compounds. However, overall, during storage, there was an increase in bioaccessibility. This suggests that HPP influences cell structure, favoring compound release and micelle formation. HPP is a sustainable method that preserves or enhances carotenoid extractability in ready-to-drink fruit beverages. Furthermore, the incorporation of dietary fiber from carrot processing discards supports circular economy practices and enhances the health potential of the product. Full article

In the EU and Great Britain (GB), all health claims (HCs) on food must be authorised before use and should comply with Regulation 1924/2006. In GB, all HCs, authorised or not, are listed in the Great Britain Nutrition and Health Claims Register. This study reviews the prevalence and compliance of HCs on prepacked foods sold within three GB supermarkets and via their grocery shopping websites. In June 2023, food labels and online product information of 440 products were evaluated across three food categories—dairy and dairy alternatives; fruit juices, fruit juice drinks and fruit smoothies; and teas and infusions. In store, 26.3% of products carried an HC and 28.3% online. The prevalence of HCs was higher when compared with data from 2016. Overall compliance was high, in store (94.3%) and online (90.0%), with no statistically significant difference in overall HC compliance between in store and online products (p = 0.724). The HC violations observed in the present study were due to non-compliant wording of HCs or use of non-authorised HCs. This study demonstrates changes in the HC landscape and the need for continued monitoring of the prevalence and compliance of HCs as consumer trends alter. Full article

This study aimed to compare newly developed diabetes-specific complete smoothie formulas with a standard diabetes-specific nutritional formula (DSNF) regarding their effects on glucose homeostasis, insulin levels, and lipid metabolism in obese type 2 diabetes (T2DM) patients. We conducted a randomized, double-blind, crossover study with 41 obese T2DM participants to compare two developed diabetes-specific complete smoothie formulas, a soy-based regular smoothie (SM) and a smoothie with modified carbohydrate content (SMMC), with the standard DSNF, Glucerna. Glycemic and insulin responses were assessed after the participants randomly consumed 300 kilocalories of each formulation on three separate days with a 7-day gap between. Postprandial effects on glycemic control, insulin levels, and lipid metabolism were measured. SMMC resulted in a significantly lower glucose area under the curve (AUC_0–240) compared to Glucerna and SM (p < 0.05 for both). Insulin AUC_0–240 after SMMC was significantly lower than that after SM and Glucerna (p < 0.05). During the diets, the suppression of NEFA was more augmented on SM, resulting in a less total AUC_0–240 of NEFA compared to the SMMC diet (p < 0.05). C-peptide AUC_0–240 after SMMC was significantly lower than that after Glucerna (p < 0.001). Conversely, glucagon AUC_0–240 after SMMC was significantly higher than that after SM and Glucerna (p < 0.05). These results highlight SMMC as the better insulin-sensitive formula, potentially achieved through increased insulin secretion or a direct reduction in glucose absorption. The unique composition of carbohydrates, amino acids, and fats from natural ingredients in the smoothies may contribute to these positive effects, making them promising functional foods for managing diabetes and obesity.

The market for protein-based drinks is endlessly growing, as the awareness of health-conscious consumers demands a shift from traditional protein smoothies or shakes to clear beverage alternatives that address thirst and hydration. The aim of this study was to investigate the soft drink market on a global scale with a focus on commercially available high-protein soft drinks, carbonated and uncarbonated, from both animal- and plant-based protein sources. Additionally, the physicochemical properties of 25 selected protein soft drinks from the market research were evaluated, including their protein content, density, viscosity, particle size, stability, pH and total titratable acidity (TTA), to explore their quality attributes. From the market research, 6.8% was the highest protein content found out of 138 beverages, with whey protein isolate and collagen hydrolysate being the most popular added protein ingredients. Only 18% of the market contained plant-based proteins, with pea protein isolate being the most common. The pH of all beverages showed acidic values (2.9 to 4.2), where TTA ranged from 0.4 to 1.47 mL (0.1 M NaOH/mL). Protein content, density and viscosity in all beverages exhibited a significantly strong positive correlation. The protein soft drink containing beef protein isolate stood out for highest protein content, density, particle size and TTA. Overall, these results demonstrate the effects and correlations of the different formulations on the quality characteristics. Therefore, the presented results can be utilized in the development and formulation of future protein soft drinks, including nutritional improvement and optimum quality, meeting current consumer trends and that are used as a convenient pre- or post-workout drink for individuals seeking muscle growth and repair.

(1) Background: Poor palatability, large volume, and lack of variety of some liquid and powdered protein substitutes (PSs) for patients with phenylketonuria (PKU) and tyrosinemia (TYR) can result in poor adherence. This study aimed to evaluate a new unflavoured, powdered GMP-based PS designed to be mixed into drinks, foods, or with other PSs, in patients with PKU and TYR. (2) Methods: Paediatric and adult community-based patients were recruited from eight metabolic centres and prescribed ≥1 sachet/day (10 g protein equivalent (PE)) of the Mix-In-style PS over 28 days. Adherence, palatability, GI tolerance, and metabolic control were recorded at baseline and follow-up. Patients who completed at least 7 days of intervention were included in the final analysis. (3) Results: Eighteen patients (3–45 years, nine males) with PKU (n = 12) and TYR (n = 6) used the Mix-In-style PS for ≥7 days (mean 26.4 days (SD 4.6), range 11–28 days) alongside their previous PS, with a mean intake of 16.7 g (SD 7.7) PE/day. Adherence was 86% (SD 25), and GI tolerance was stable, with n = 14 experiencing no/no new symptoms and n = 3 showing improved symptoms compared to baseline. Overall palatability was rated satisfactory by 78% of patients, who successfully used the Mix-In-style PS in various foods and drinks, including smoothies, squash, and milk alternatives, as a top-up to meet their protein needs. There was no concern regarding safety/metabolic control during the intervention. (4) Conclusions: The ‘Mix-In’-style PS was well adhered to, accepted, and tolerated. Collectively, these data show that providing a flexible, convenient, and novel format of PS can help with adherence and meet patients’ protein needs. Full article

Smoothie drinks are currently very popular drinks sold especially in fast food establishments. However, smoothies are a significant source of microorganisms. The aim of this study was to evaluate the microbiological quality of smoothies purchased in Eastern Bohemia. A higher prevalence of mesophilic aerobic bacteria (5.4–7.2 log CFU/mL), yeast (4.4–5.9 log CFU/mL) and coliform bacteria (3.1–6.0 log CFU/mL) was observed in vegetable smoothies, in which even the occurrence of enterococci (1.6–3.3 log CFU/mL) was observed. However, the occurrence of S. aureus, Salmonella spp. and Listeria spp. was not observed in any samples. Nevertheless, antimicrobial resistance was observed in 71.8% of the isolated strains. The highest level of resistance was found in isolates from smoothie drinks with predominantly vegetable contents (green smoothie drinks). Considerable resistance was observed in Gram-negative rods, especially to amoxicillin (82.2%) and amoxicillin with clavulanic acid (55.6%). Among enterococci, only one vancomycin-resistant strain was detected. The vast majority of isolated strains were able to form biofilms at a significant level, which increases the clinical importance of these microorganisms. The highest biofilm production was found in Pseudomonas aeruginosa, Kocuria kristinae and Klebsiella pneumoniae. Overall, significant biofilm production was also noted among isolates of Candida spp. Full article

Introduction: Our diet is the sum of many different influences and has visibly changed over the past decades. Since children also imitate their parents when it comes to eating habits, the aim of the study was to assess the current dietary habits in Swiss children. Method: Cross-sectional study of children between 0 and 18 years of age in Switzerland. Results: A total of 1964 children participated, with an average age of 7.4 years. A total of 57.9% of participants stated to buy supplements to promote health, while fruit juices/smoothies were the most popular product (42.5%), followed by protein-enriched products (40%) and vitamins/minerals (29%). A statistically significant correlation between longer screen time, a higher socioeconomic background, and the intake of supplements was found. Over 20% of all families regularly consume plant-based drinks. Discussion: This Swiss cross-sectional study of over 1900 participants reveals that 58% of all participants buy supplements or special kid’s food to promote the child’s health. There is a correlation between higher screen time, higher parental income, and the usage of supplements. A total of 23% of participating families consume at least one plant-based drink on a regular basis. As more and more families use supplements, the pediatrician should not only focus on weight, which reflects the intake of macronutrients but should also take a history of whether children omit certain foods or take supplements to ensure the child does not have a deficiency of micronutrients.

Acidic drinks are known to exert negative effects on the surface properties of dental restorative materials. However, the effect of increasingly popular green smoothie drinks has not been addressed so far. The present study investigated the effect of cyclic immersions (5 min daily over 30 days) in a green smoothie drink on the surface properties of contemporary dental restorative materials, including resin composites, an alkasite, and a glass hybrid. Vickers microhardness, profile roughness, and perceptible color change in the CIE L* a* b* color space were evaluated as clinically relevant properties of the material surface. After 30-day green smoothie immersion, microhardness values either decreased by 8–28% (for resin composites) or increased by up to 91% (for glass hybrid). The increase in profile roughness (Ra parameter) of smoothie-immersed specimens was 7–26 times higher compared to the control group. The perceptible color change (ΔE*) in the smoothie group was 3–8 times higher compared to the control group. Overall, this study demonstrated that daily exposure of dental restorations made from resin composites, alkasites, and glass hybrid materials to a green smoothie drink can significantly accelerate material degradation, which is reflected as surface softening, as well as higher roughness and higher perceptible color change.

Food consumed away from home is contributing an increasing proportion of household food budgets in New Zealand (NZ). This study aimed to benchmark the healthiness of the NZ fast-food supply in 2020. Data on the serving size and nutrient content of products were collected from company websites and in-store visits of 27 fast-food chains. For each fast-food category and type of combo meal, the medians and interquartile ranges were calculated for serving size (g/mL) and energy (kilojoules-kJ), sodium (mg), total sugar (g) and saturated fat (g) per serving. The nutrient contents/servings were benchmarked against the United Kingdom (UK) soft drinks levy thresholds and targets for salt for foods consumed away from home; the NZ daily intake guidelines for energy, sodium and saturated fat; and the WHO recommendation for free sugars. Nutrition information was available for 1777 products and 176 meal combos. More than one in ten drinks would qualify for a UK soft drinks levy, and 47% (n = 1072) of products with sodium data exceeded the relevant UK targets. The categories with the highest median energy and nutrient contents per serving were: burgers (2585 kJ-energy and 1091 mg-sodium), savoury pastries (13 g saturated fat) and milkshakes/smoothies (49 g total sugar). The meal combos represented one meal occasion, but an average combo provided 50% of the daily energy requirement, 89% of the maximum sodium recommendation, 81% of the recommended sugar intake, and 46% of the recommended saturated fat intake. Fast-food products and combo meals in NZ contribute far more energy and negative nutrients to the recommended daily intake targets than is optimal for good health. The NZ Government needs to set reformulation targets and portion-size guidance to reduce the potential impact that increasing fast-food consumption is likely to have on the health of New Zealanders. All fast-food chains need to provide sufficient nutrition information about their products to inform consumers. Full article

Raw foodstuffs have been marked as a healthier alternative in the context of nutrient content and are becoming more popular with consumers. Thermally untreated foods may represent a microbiological risk connected with the possible presence of antimicrobial resistance. The aim of this study was to prove that popular raw food beverages such as smoothies and raw milk may be a source of antibiotic-resistant coliform bacteria and resistant genes. The majority of antibiotic-resistant isolates (110) were identified as Enterobacter spp., Escherichia coli, and species of Klebsiella spp., predominantly β-lactam and chloramphenicol resistant. Multidrug resistance has been registered in one-third of resistants. Overproduction of efflux pumps was clarified in 8 different bacteria. The majority of resistant isolates were strong biofilm producers. Antibiotic resistance gene bla_OXA was detected in 25% of isolates, especially in E. coli. Resistance genes bla_TEM and bla_SHV were detected in 19% and 14%, respectively. This is the first study to point out that popular raw drinks such as smoothies or raw milk, besides their nutrient benefits, could represent a reservoir of antibiotic-resistant bacteria as well as antibiotic resistance genes. According to this, raw drinks could contribute to the dissemination of antibiotic resistance in the human gastrointestinal tract and environment. Full article

Postharvest losses of mango fruit in a number of developing countries in Africa and Asia have been estimated to be as high as over 50%, especially during the main harvest season. Micro, small, and medium scale food processing enterprises play an important economic role in developing economies in processing of a diversity of healthy food products as a sustainable way to reduce postharvest losses and food waste, extend shelf life of food, boost food security, and contribute to national gross domestic product. Processing of mango fruit into the diverse shelf-stable products makes the seasonal fruit conveniently available to consumers all year round. Over the years, research and food product development have contributed substantially to a number of unique and diverse processed mango products with specific qualities and nutritional attributes that are in demand by a wide array of consumers. These mango products are derived from appropriate food processing and value-addition technologies that transform fresh mango into shelf-stable products with ideal organoleptic, nutritional, and other quality attributes. Some of the common processed products from mango fruit include pulp (puree), juice concentrate, ready-to-drink juice, nectar, wine, jams, jellies, pickles, smoothies, chutney, canned slices, chips, leathers, and powder. Minimum processing of mango fruit as fresh-cut product has also gained importance among health-conscious consumers. Apart from the primary products from mango fruit, mango pulp or powder can be used to enrich or flavor secondary products such as yoghurt, ice cream, beverages, and soft drinks. Byproducts of mango processing, such as the peel and kernel, have been shown to be rich in bioactive compounds including carotenoids, polyphenols, and dietary fibers. These byproducts of mango processing can be used in food fortification and manufacture of animal feeds, thereby gaining greater value from the fruit while reducing wastage. This review focuses on the current trends in processing and value addition of mango applicable to small-scale processors in developing countries. Full article

This study investigated the status of bioactive compounds (phenolic compounds, carotenoids, and vitamin C), changes in color performance, and microbiological quality in smoothies preserved by high-pressure processing (HP) and thermal pasteurization (P) during cold storage at 4 °C for 21 days. Chemometric tools were used to select relevant variables that represent the most useful information for the fast and accurate quality assessment of smoothies. HP was performed at 350 and 450 MPa for 5 and 15 min at room temperature, respectively, while P was performed at 85 °C for 7 min. Smoothies were prepared by blending juices of apple (50%, v/v), carrot (20%, v/v), chokeberry (5%, v/v), Indian banana puree (10%, w/v), and almond drink (15%, v/v). The results obtained indicated that lower pressures with a shorter duration of HP showed higher levels of bioactive compounds in the smoothies, compared to the control samples. Compared to P, the HP samples exhibited a greater stability of bioactive compounds during shelf life. HP was found to be highly effective in reducing the native microflora of the smoothies, without subsequent microbial activation during storage. This study demonstrated the usefulness of the chemometric approach in interpreting complex datasets for the effective quality assessment of smoothies treated with different preservation technologies.
