This study aims to increase knowledge of the ability of nutrition labels to guide consumer choices in real-life environments.

Food consumption and plate waste data were collected from two self-service restaurants (SSR) with different customer groups over six observation days: three control and three intervention (with nutrition labelling) periods. Study Group 1 consisted of vocational school students, mostly late adolescents (N = 1,710), and Group 2 consisted of spa hotel customers, mostly elderly (N = 1,807). In the experimental restaurants, the same food was served to the buffets during the control and intervention periods.

The nutrition label in the lunch buffet guides customers to eat fewer main foods and salads and to select healthier choices. Increased consumption of taste enhancers (salt and ketchup) was observed in the study restaurants after nutritional labelling. Nutrition labelling was associated with a reduction in plate waste among the elderly, whereas the opposite was observed among adolescents.

The results provide public policymakers and marketers with a better understanding of the effects of nutrition labelling on consumer behaviour. Future studies should further evaluate the effects of nutrition labelling on the overall quality of customer diets and the complex environmental, social, and psychological factors affecting food choices and plate waste accumulation in various study groups.

After reading and discussing this case study, students will be able to explain the concept of diffusion of innovation and predict how the passion fruit-infused vinaigrette (PFIV) might spread throughout the Thai market; analyze the market environment for condiments in Thailand and identify specific opportunities that Preedha Vinchit and her team should consider for the successful launch of the PFIV; interpret both qualitative and quantitative data gathered by the new product development (NPD) team and discuss its implications for the product’s market strategy and development; and critique the initial launch plan proposed by Krit Anon, suggest practical strategies and calculate the break-even point necessary to meet the project’s financial goals.

During July 2023, Vinchit, product marketer at the Thani Food Institute (TFI), faced a critical decision regarding the launch of the APFIV. Developed from TFI’s patented passion fruit peel powder, the PFIV offered functional benefits and addressed the sustainable use of passion fruit resources. As COVID-19 restrictions eased, TFI’s board of advisors anticipated a successful market entry for PFIV. Anon, culinologist and chef behind PFIV’s formulation, expressed keen interest in launching it independently with a startup investment of THB 500,000 (US$14,388). Vinchit, with market research and home-use test results indicating positive consumer reception in hand, contemplated whether to proceed with a launch plan of TFI’s design or endorse Anon’s entrepreneurial venture. Critical considerations included market viability, strategic partnerships, target demographics and marketing strategies encompassing pricing, distribution and promotional campaigns. The decision hinged on maximizing PFIV’s market potential amidst Thailand’s robust condiment consumption and growing health awareness.

This case study can be used in undergraduate and graduate courses in entrepreneurship, food product development, marketing strategy, market research and innovation on topics including NPD, opportunity identification, concept testing, consumer research analysis, marketing strategy formulation, business/financial analysis and launch strategies. This case study may be more useful in the middle or later parts of a course or module when an instructor is focusing on any or all stages of the NPD process and the strategic decisions, particularly for aspiring entrepreneurs with limited resources. Additionally, students should have developed at least some preliminary understanding of qualitative and quantitative research methods. This case study has been very effective in demonstrating various organizational processes and decision-making tools, which allow students to apply strategy frameworks and systematically evaluate several alternatives.

This study aims to understand client food preferences and how pantry offerings can be optimized by those preferences.

This study develops and administers customized surveys to study three food pantries within the Second Harvest Food Bank of Northwestern North Carolina network. This study then categorizes food items by client preferences, identifies the key predictors of those preferences and obtains preference scores by fitting the data to a predictive model. The preference scores are subsequently used in an optimization model that suggests an ideal mix of food items to stock based upon client preferences and the item and weight limits imposed by the pantry.

This study found that food pantry clients prefer fresh and frozen foods over shelf-friendly options and that gender, age and religion were the primary predictors. The optimization model incorporates these preferences, yielding an optimal stocking strategy for the pantry.

This research is based on a specific food bank network, and therefore, the client preferences may not be generalizable to other food banks. However, the framework and corresponding optimization model is generalizable to other food aid supply chains.

This study provides insights for food pantry managers to make informed decisions about stocking the pantry shelves based on the client’s preferences.

An emerging topic within the humanitarian food aid community is better matching of food availability with food that is desired in a way that minimizes food waste. This is achieved by providing more choice to food pantry users. This work shows how pantries can incorporate client preferences in inventory stocking decisions.

This study contributes to the literature on food pantry operations by providing a novel decision support system for pantry managers to aid in stocking their shelves according to client preferences.

This study aimed to investigate the relationship between food sponsorships and gender stereotypes, focusing on how patriarchal beliefs influence consumers’ purchase intentions in sports.

The research comprised two studies. In Study 1, n = 161 participants participated via Amazon’s Mechanical Turk platform. Study 2 involved n = 250 participants who completed a cross-sectional and self-administered survey.

Study 1 indicated an apparent gender-based categorization of certain foods and beverages: beer and red meat were predominantly perceived as masculine, while yogurt, salads, and wine were seen as feminine. Further, brands like Budweiser and Red Bull were mainly seen as masculine, while Chobani and Smoothie King were perceived as feminine. Moreover, findings indicate that foods, especially those rich in protein or linked to BBQ and spicy tastes, are considered more masculine by men than women in sports settings. Further, Study 2 findings unveiled a significant relationship between patriarchal beliefs and both attitudes (ß = 0.327, p < 0.01) and subjective norms (ß = 0.525, p < 0.01) towards masculine brands.

The two studies’ results underscore the profound impact of gender stereotypes shaping sports fans’ perceptions of food items and the brands sponsoring them. This inquiry significantly augments the current understanding of the nuanced interrelation between the paradigms of social role theory and the theory of planned behavior, particularly within the ambit of sports-related sponsorship by food and beverage brands and its consequent influence on consumer purchasing inclinations.

This study aims to assess the oxidative stability of avocado oil (AO) at various temperatures, using butylated hydroxytoluene (BHT) as an artificial antioxidant and different concentrations of ultrasonic extract of Chlorella vulgaris.

Extracts of C. vulgaris were obtained using four solvents: water, acetone, ethanol and 80% ethanol-aqueous. Standard techniques were used to conduct qualitative phytochemical screening of the extracts. The extracted samples were analyzed for total phenolics, total flavonoids, antioxidant activity and phenolic compound fractionation. Some physicochemical parameters of AO treated with various concentrations of C. vulgaris ultrasonic extract compared to a 200 ppm BHT and exposed to different temperatures were measured.

The highest phenolic, flavonoids content and antioxidant activity was achieved by 80% ethanolic extract of C. vulgaris . The results showed that exposure of AO to high temperatures led to significant changes in the oil's physicochemical properties. These changes increased as the temperature increased. On the other hand, adding 80% ethanolic extract of C. vulgaris into AO reduced the effect of heat treatment on the change in physicochemical properties.

Adding 80% ethanolic extract of C. vulgaris into AO can potentially reduce the impact of heat treatment on the alteration of physicochemical properties.

This paper studies digitalization projects aiming to increase the share of regional food in the hospitality sector and communal catering. The focus is set on influencing factors and underlying feedback structures that arise through the digitalization of regional food supplies. The results can guide stakeholders to get a better understanding of key influencing factors and complexities from a holistic perspective.

A systems thinking approach is employed to model regional food networks. The influencing factors were found in the literature and in two model regions. Feedback loops and underlying structures were explained and validated through semi-structured interviews. Findings are visualized in causal loop diagrams (CLDs) and are used for theory development.

The presentation in CLDs helps understanding the influence of digital logistics platforms on the entire system of regional food supply and not just on isolated parts. Among others, cooperation, trust and digital solutions were identified as key success factors when aiming to increase the share of regional food in the hospitality sector and communal catering.

The work focused on the underlying feedback structures occurring in regional food supply in two, rural Bavarian regions in Germany with their unique geographical settings. Findings may, consequently, not be entirely transferable to other regions with varying characteristics. Further research needs to be done to see how much these regional parameters influence digital logistics platforms.

The paper contributes to the existing scientific literature by showing the impact coming from digital logistics platforms on regional food supply systems. Developing CLDs provides a basis for future work and facilitates discussion for researchers and practitioners to support future real-world implementations.

The study estimates the willingness to pay for organic oranges and identifies its influencing factors among consumers in the Mekong Delta, Vietnam.

The study used survey data from 413 households in the Mekong Delta from March 2022 to July 2022. The choice experiment (CE) and contingent valuation method (CVM) were employed to analyze consumers’ willingness to pay (WTP). STATA 17 software was used to analyze research data in the logit model and mixed logit model.

The research results from the CVM approach show that a number of demographic characteristics have a direct impact on WTP, such as education, educational attainment, family size, the presence of children and the elderly in the household, food safety and environmental awareness. The CE model shows product attributes that influence consumers’ WTP, such as country of origin, traceability, quality grade, organic certification, ecolabel and organic content. Both approaches show that price is the main barrier to organic orange consumption.

The study surveyed four large cities in four provinces representing the Mekong Delta region.

Our study helps administrators have a deeper insight into consumer preferences and behavior, specifically the factors that affect consumers' WTP, an important indicator of demand for the success of manufacturers and marketers in developing as well as improving marketing strategies. Knowledge of a product’s WTP on behalf of (potential) customers plays an important role in many areas of marketing management, such as pricing decisions or new product development.

Furthermore, this understanding will inform policymakers about the future of agricultural markets in Vietnam and help them better prepare for the making of sustainable agricultural policies. Develop organic agriculture to both protect human health, protect the living environment and protect the soil from degradation, ensuring sustainable agricultural production. This is also one of the measures to help people stay away from diseases to limit the social burden.

The study confirms that both CVM and CE models can be used to estimate WTP. However, CVM fits the overall WTP estimate, while CE is more appropriate when estimating WTP for individual scenarios through combining attributes with different levels.

Explore the role of traditional cafés in Lisbon and botequins in Rio de Janeiro in the history and culture of their respective cities, based on an analysis of the comments published on TripAdvisor.

Using a mixed methodology, 7,430 evaluations were analyzed, of which 5,473 were for Portuguese cafés and 1,957 for Brazilian botequins. A content analysis and statistical treatment were carried out. A line-by-line analysis was also conducted to code the emotions reported in the customer reviews.

The analysis categorized the comments into Gastronomy, Nostalgia, History and Heritage, and Quality of Service. Nostalgia garnered the highest percentage of positive comments for both Portuguese cafés and Brazilian botequins. These results emphasize the importance attached to sentimental connections and historical narratives, particularly those associated with notable individuals who frequented these places. Furthermore, no statistically significant differences were identified according to the type of establishment, which suggests a consistent pattern between cafés and traditional botequins.

Draws attention to the importance of a collaborative partnership between restaurant owners and tourism authorities. This strategic alliance not only serves to raise the cultural profile of cities, but also generates substantial economic benefits. It also ensures the lasting legacy of these historic establishments, celebrating the past, enriching the present and safeguarding the future.

Studying the cafés of Lisbon and the botequins of Brazil is important not only for understanding the history and culture of these countries but also for analyzing issues related to socialization, identity, artistic expression and urban transformations.
