Emotional response to healthier foods: Influence of culture and health consciousness.

Sugar, salt, and fat content in processed products are important concerns for consumers. Hence, alternative "healthy" versions of conventional foods such as chocolate, potato chips, and yogurt are offered. This work aimed to define the emotional response of consumers from different cultural backgrounds (Spain vs. Brazil) evoked by healthier versions of conventional products and the relationship between hedonic responses and health consciousness. A total of 186 Brazilian and 152 Spanish consumers participated in this online cross-cultural study. Participants answered a Health Consciousness Questionnaire and an emotional check-all-that-applies questionnaire using picture stimuli of conventional chocolate, potato chips, and yogurt and their healthier versions with less sugar, salt, and fat content, respectively. The Brazilians' emotional responses were more diverse for all stimuli compared to the Spaniards'. However, participants from both cultures rated an average of "slightly agree" on the health consciousness scale; a higher level of consumption, liking, and willingness to buy; and a higher frequency of positive emotional terms for the stimuli of conventional products compared to their healthier versions. A higher frequency of evocation of "active" is strongly associated with higher levels of health consciousness. Strategic actions by the food industry and government must consider cultural, emotional, and health-conscious factors to encourage the consumption of healthier foods. PRACTICAL APPLICATION: Food manufacturers can use the information obtained from this study to create healthier versions of their products that appeal to consumers' emotional responses and health consciousness levels. The findings can assist in designing strategic actions to promote healthier food consumption by emphasizing the benefits of healthier food choices and making them more appealing to consumers. The methodology employed in this study can also be applied to further studies aimed to assess emotional responses to food stimuli across different cultures.

Influence of fat reduction and flavor addition on the temporal sensory profile in potato chips using a multiple-intake approach.

BACKGROUND: Reducing the fat content of potato chips can negatively affect the overall perception of taste and texture. However, incorporating flavor can help mitigate negative effects. To measure and understand these changes, a technique describing the consumption experience must be used. The impact of low fat content and the presence of ham flavor in the formulation of potato chips was studied in relation to the dynamics of sensations perceived during consumption and, additionally, related to the hedonic aspects of these products. RESULTS: Three different varieties of commercially available potato chips, classical salted potato chips (PC-C), light (low fat content) potato chips (PC-L), and ham-flavored potato chips (PC-H), were analyzed by multiple-intake temporal dominance of sensations (TDS) sessions, showing the differences among PC-C, PC-L, and PC-H. Moreover, acceptability and purchase intention were also considered. The results showed that the lower fat content in the potato chips had a great impact on temporal dominance of texture attributes, whereas the presence of ham flavor in the formulation greatly modified the temporal dominance of flavor sensations during consumption with no effect on acceptability. CONCLUSION: Multiple intake TDS is a suitable method for revealing how modifications of formulation and composition of potato chips to achieve healthier or different versions affects consumers dynamic sensory perception and how it is related to preferences. © 2023 Society of Chemical Industry.

Cross-cultural emotional response to food stimuli: Influence of consumption context.

Emotional responses elicited by certain types of food can be influenced by past experiences, frequency of consumption, culture, and other personal preferences. The present research aimed i) to investigate the impact of culture (Brazilian and Spaniard) on consumers' emotional responses and acceptability of different food stimuli, and ii) to explore the influence of evoked contexts. Brazilian (n = 437) and Spanish (n = 397) participants were exposed to three visual food stimuli (image of chocolate, potato chips, and yogurt) in an online survey and reported their emotional responses. Sociodemographic data, liking, and frequency of consumption were also collected. The evoked context in our study were designed and proposed, for each product and culture, based on four dimensions (consumption time, location, social setting, and hungry state). The evoked emotional lexicon was different for each food stimulus and was clearly influenced by the cultural factor. However, there are more similarities between cultures when evaluating the same product category. The evoked contexts were appropriated and influenced the citing frequency of some emotion terms, including positive ones. The most cited emotion terms tended to positively impact product liking ratings, acting as drivers of liking. Consumption level was positively related to liking regardless of cultural interactions for both chocolate and potato chips stimuli. In conclusion, the cultural background demonstrated to be an important impact factor to be considered for understanding the effects of product, consumption occasions, and degree of liking, on emotional responses to foods. These findings offer new possibilities to be explored in marketing messages for interventions or stimuli that guide food choices.

Benefits of wine-based marination of strip steaks prior to roasting: inhibition of protein oxidation and impact on sensory properties.

BACKGROUND: The objective of this study was to evaluate the impact of red wine-based marination on the oxidative stability and overall quality of roasted beef strip steaks. Four treatments were considered, according to the type of wine (300 mL dealcoholized wine/kilogram meat): 'Cabernet Sauvignon', 'Tempranillo', 'Isabel' (ISA), and a control. The formation of potentially harmful protein oxidation products during roasting, including protein carbonyls and dityrosines, was inhibited by bioactive components of the wine. RESULTS: ISA marinades were particularly resistant to protein oxidation, which could be due the particular composition of this wine in phenolic compounds. Wine-based marination was also effective in controlling the formation of lipid-derived volatile compounds, such as hexanal, octane-2,5-dione, and heptan-2-one, which led to a reduced perception of rancidity by panelists. Additionally, wines contributed to spicing roasted beef with wine-derived flavors from esters, alcohols, and lactones. CONCLUSIONS: Hence, marination may be a feasible means to alleviate the potential negative effects that oxidative reactions cause to meat proteins, improve beef quality, and diversify beef cuts into a variety of safer and more flavored meat products. Among wines, ISA appeared to be most promising in terms of antioxidant protection; however, the limited consumer acceptance of steaks treated with this wine may be regarded as a drawback to be sorted out in future studies. © 2018 Society of Chemical Industry.
