Immune-Boosting Functional Foods: A Potential Remedy for Chinese Consumers Living Under Polluted Air

The deterioration of air quality in China has resulted in many people looking for remedies to counteract the impact that air pollution is perceived to be having on their health. As the importance of diet on immune health is becoming increasingly well recognised, a narrative literature review was undertaken to elucidate Chinese consumers’ acceptance of functional food products designed to help the immune system recover from pollution-driven impact and to assess their market potential. Consumers’ attitude towards immune-boosting functional foods were mainly positive, with scientific validation being important in determining the credibility of a product. This was despite the fact that the effectiveness of the functional food products currently in the market that purported to be remedies for pollution-driven impacts on the lung did not appear to be supported by scientific evidence. Numerous studies have reported functional foods could provide a wide range of benefits to immune health, including helping pollution-driven immune issues. This review highlights the market demand for effective and scientifically-proven functional food products that help Chinese consumers’ immune system recover from the impact of air pollution

Determining How Chinese Consumers that Purchase Western Food Products Prioritize Food Safety Cues: A Conjoint Study on Adult Milk Powder

This study investigated how Chinese consumers prioritize cues when assessing the safety of imported milk powder. A choice-based conjoint survey was completed by 307 participants in Beijing, Shanghai, Tianjin, and Nanjing, using the internet-based software 1000minds. Important cues for consumers were “government certification logo shown on the product label/Website”; “ingredients and materials, free from preservatives and additives”; “having traceability techniques such as QR code included” and “realistic photos.” Distinct consumer segments reflecting differing trade-offs between safety cues were not detected suggesting that a single food safety communication strategy for this market may be sufficient. These findings add to extant literature by highlighting what cues give consumers the most confidence a product is safe and they provide a raft of actionable insights for government and the food industry in terms of designing and implementing effective risk or market communication strategies for Chinese consumers

A Systematic Review of Consumer Perceptions of Smart Packaging Technologies for Food

Smart packaging, an emerging technology in the food packaging industry incorporates both active and intelligent technologies. Consumer demand for natural products and increasingly extended and diverse supply chains required to feed the growing global population, mean that traditional packaging is becoming less capable of meeting the functional demands placed on it. To help ensure the commercial success of proposed smart packaging technologies a thorough understanding of consumers attitudes toward them is required. Understanding the cultural, social and cognitive factors that affect acceptance will help “fine tune” smart packaging development to best meet consumer preferences and needs and ensure that communication about the technologies effectively addresses consumer concerns and educates them on the benefits. This systematic review of 28 peer reviewed journal articles summarizes the current knowledge on consumer acceptance or rejection of active and intelligent packaging, and the behavioral forces behind those attitudes. Articles containing primary data and published in the English language over the last 10 years reporting consumer responses to active and/or intelligent packaging technologies in general or to more specific technologies that achieved the functional goals of active or intelligent packaging were obtained and analyzed for themes in the qualitative data analysis software NVivo. Themes were organized into groups as to whether they identified control variables, moderating variables, barriers or motivations to purchase and the benefits of the technology. To develop a conceptual framework for understanding consumer preferences for smart packaging, the identified themes were integrated with several consumer behavior models including the theory of planned behavior and an attitude model. Consumer perceptions of smart packaging is a poorly covered research area with most research being clustered in Europe and a smaller cluster in the Americas so there were significant opportunities to build on the body of knowledge

Functional Beverages in Selected Countries of Asia Pacific Region: A Review

Functional beverages have gained increasing market share over the last decade. As the Asia Pacific region is one of the largest and most important markets for functional foods, it is critical when developing and promoting new products that food manufacturers/marketers have a good understanding of the Asia Pacific market, including the legislative requirements and consumers’ perceptions of functional beverages. A literature review was undertaken to elucidate legislation criteria and consumers’ perceptions of functional beverages in Asia Pacific countries. Topics reviewed included the origin and definitions of functional foods and beverages; the legislative criteria for functional foods and beverages in four representative countries—Australia, New Zealand, China, and Japan; and consumers’ perceptions of functional beverages. There was no concrete definition of “functional food” or “functional beverage” region-wide and correspondingly, the legislative terms and regulatory frameworks for functional foods and beverages varied from country to country and showed divergence due to cultural differences. The systematic review of consumer perceptions of functional beverages showed that product acceptance and purchase intention for different functional beverages was heterogeneous among consumers in the Asian Pacific Region, with many factors playing a role including product attributes (e.g., functional attributes, sensory attributes, and product form) and consumer perceptions (e.g., health motivation, trust in food industry, and food neophobia). The findings from this review will help guide product development and inform marketing strategies for functional beverages targeting the Asia Pacific region by providing information on legislation and consumers’ perceptions

Vietnamese Consumers’ Preferences for Functional Milk Powder Attributes: A Segmentation-Based Conjoint Study with Educated Consumers

This paper investigated Vietnamese consumers’ preferences for functional milk powder products to determine if there were differences in market segments. A Qualtrics survey and a 1000minds choice-based conjoint survey were completed by 272 participants, predominantly 18-30-year-old males with high education levels and above average incomes. Firstly, general perceptions of the use of functional foods to maintain health were determined, with results revealing that participants believed in the benefits the foods claim to provide. Secondly, participants’ tradeoffs for specific extrinsic functional milk powder attributes were determined by examining the relative importance they placed on a range of attributes. Participants prioritized a quality stamp attribute and preferred that this was obtained from an international certification body. Finally, a two-step cluster analysis and multinomial logistic regression was used to profile the participants and analyze relationships between socio-demographic data and the four resulting segments (i.e., Food Safety Concerned, Price Sensitive, Premium Product Focused, and Nutrition Focused). The largest of these segments was Food Safety Concerned (46.3%) with males significantly less likely than females to be in this segment. Given the limited literature on Vietnamese consumers’ decision-making processes, this study is an important contribution to this topic, as well as providing information about market opportunities

Chinese consumers’ perceptions of food safety cues and maximising the effectiveness of food safety communications

Food safety is an issue of key concern for Chinese consumers. This study identifies intrinsic and extrinsic cues on product labels or websites that Chinese consumers use to assess a product’s perceived safety. Five structured focus groups (total participants n 5 41) were run in Suzhou China, in Chinese, to gather consumers’ perceptions towards food safety cues. A total of 18 safety cues were identified during the focus group discussions. Certifications, country of origin, production date and shelf life, ingredients and materials and nutritional information were the five safety cues consumers perceived to be the most important. The risks perceived by consumers differed based on: product category (e.g. meat, dairy, cereal); product form (e.g. fresh, chilled, frozen) and degree of processing. Interestingly, consumers used different food safety cues to assess a packaged product compared to the product shown on a website. While providing deep qualitative insights into perceptions of food safety cues, further studies which seek to conduct quantitative work within a wider demographic context are encouraged. This information will help to provide best practice advice for international marketers and government risk communicators on how and where to communicate the safety of food products so that they can maximise the effectiveness of their messaging within the appropriate information channels and thereby ensure that it resonates well with Chinese consumers. This study contributes to the academic knowledge of consumer perceptions of cues related to food safety

Review of Online Food Delivery Platforms and their Impacts on Sustainability

During the global 2020 COVID-19 outbreak, the advantages of online food delivery (FD) were obvious, as it facilitated consumer access to prepared meals and enabled food providers to keep operating. However, online FD is not without its critics, with reports of consumer and restaurant boycotts. It is, therefore, time to take stock and consider the broader impacts of online FD, and what they mean for the stakeholders involved. Using the three pillars of sustainability as a lens through which to consider the impacts, this review presents the most up-to-date research in this field, revealing a raft of positive and negative impacts. From an economic standpoint, while online FD provides job and sale opportunities, it has been criticized for the high commission it charges restaurants and questionable working conditions for delivery people. From a social perspective, online FD affects the relationship between consumers and their food, as well as influencing public health outcomes and traffic systems. Environmental impacts include the significant generation of waste and its high carbon footprints. Moving forward, stakeholders must consider how best to mitigate the negative and promote the positive impacts of online FD to ensure that it is sustainable in every sense

Proton and cadmium adsorption by the archaeon Thermococcus zilligii: Generalising the contrast between thermophiles and mesophiles as sorbents

Adsorption by microorganisms can play a significant role in the fate and transport of metals in natural systems. Surface complexation models (SCMs) have been applied extensively to describe metal adsorption by mesophilic bacteria, and several recent studies have extended this framework to thermophilic bacteria. We conduct acid-base titrations and batch experiments to characterise proton and Cd adsorption onto the thermophilic archaeon Thermococcus zilligii. The experimental data and the derived SCMs indicate that the archaeon displays significantly lower overall sorption site density compared to previously studied thermophilic bacteria such Anoxybacillus flavithermus, Geobacillus stearothermophilus, G. thermocatenulatus, and Thermus thermophilus. The thermophilic bacteria and archaea display lower sorption site densities than the mesophilic microorganisms that have been studied to date, which points to a general pattern of total concentration of cell wall adsorption sites per unit biomass being inversely correlated to growth temperature

Understanding the Needs of Food-Allergic Adults

Food allergies are a growing issue, yet society’s understanding of how individuals’ lives are affected is limited. We conducted four focus groups with food-allergic adults in New Zealand to gain an in-depth understanding of the issues that impacted their quality of life. Key themes identified included allergen-free eating issues, health care system issues, costs of having a food allergy, effects on well-being, external influences (e.g., others’ lack of awareness), and internal influences (personal growth and adaptation). The unmet needs of food-allergic adults led to risk taking, increased stress, and social isolation. A lack of awareness in others (including medical professionals, food service providers, and the general public) had a negative impact, suggesting that an intervention targeting awareness would be beneficial. Adaptation, particularly in terms of assertiveness and organizational skills, was important for coping, so we suggest training in these skills be made available for food-allergic patient

Investigation of geraniol biotransformation by commercial Saccharomyces yeast strains by two headspace techniques: solid-phase microextraction Gas Chromatography/Mass Spectrometry (SPME-GC/MS) and Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS)

Hop-derived volatile organic compounds (VOCs) and their transformation products significantly impact beer flavour and aroma. Geraniol, a key monoterpene alcohol in hops, has been reported to undergo yeast-modulated biotransformation into various terpenoids during fermentation, which impacts the citrus and floral aromas of the finished beer. This study monitored the evolution of geraniol and its transformation products throughout fermentation to provide insight into differences as a function of yeast species and strain. The headspace concentration of VOCs produced during fermentation in model wort was measured using Solid-Phase Microextraction Gas Chromatography/Mass Spectrometry (SPME-GC/MS) and Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS). In the absence of yeast, only geraniol was detected, and no terpenoid compounds were detected in geraniol-free ferments. During fermentation, the depletion of geraniol was closely followed by the detection of citronellol, citronellyl acetate and geranyl acetate. The concentration of the products and formation behaviour was yeast strain dependent. SPME-GC/MS provided confidence in compound identification. PTR-ToF-MS allowed online monitoring of these transformation products, showing when formation differed between Saccharomyces cerevisiae and Saccharomyces pastorianus yeasts. A better understanding of the ability of different yeast to biotransform hop terpenes will help brewers predict, control, and optimize the aroma of the finished bee
