A cross-cultural study of acceptability and food pairing for hot sauces

Physicochemical and Sensory Evaluation Data to Drive the Development of a Green Chili Pepper Hot Sauce from Unexploited Raw Materials

The present study shows the set of analyses conducted during the development of a hot chili pepper sauce to valorize green peppers usually discarded in the Espelette region (France). A traditional production process was used as the inspiration for product development, and two different fermentation processes were assessed and characterized by measuring pH, sugar content, instrumental color, volatile composition, and conducting sensory (discriminant test) and microbiological analyses (total plate count). Significant differences were observed among pepper mash samples with respect to their physicochemical characteristics, but the products were considered similar from a sensory standpoint. Both sensory and physicochemical tests suggested that the ingredients added to make the sauces were determinant and had a higher impact on the organoleptic profile of the final product than the fermentation process. Finally, a Napping® test was conducted to determine the attributes that could differentiate the product from the hot sauces found in the current market. The results of the present research allowed the optimization of the elaboration process of the new product, saving time and ingredient costs. The procedures shown in the study could be used as an example of a new product development process in which physicochemical and sensory data are collected and used for decision making.

Development, sensitivity and reliability of a French version of the Leeds Food Preference Questionnaire (LFPQ-fr) for the evaluation of food preferences and reward

BACKGROUND

. There is a growing global interest in the evaluation of food reward, necessitating the adaptation of culturally appropriate instruments for use in empirical studies. This work presents the development and validation of a culturally adapted French version of the Leeds Food Preference Questionnaire (LFPQ-fr).

METHODS

. The LFPQ-fr was developed and validated in healthy-weight adults using the following systematic approach: i) selection and validation of appropriate food pictures; ii) linguistic translation of liking and wanting constructs in the target population (n=430; 81% female; 42.2 ± 12.7 years); iii) validation of the sensitivity and reliability of the task performed in a fasted state and in response to a standardized test meal (n=50; 50% female; 30.0 ± 8.4 years).

RESULTS

. During the first and second phases, the nutritional and perceptual validation of culturally appropriate food pictures and pertinent reward constructs, respectively, was demonstrated in a healthy-weight French sample. Findings from the third phase indicated that all food reward components were sensitive to the test meal and showed moderate to high agreement in both fasted (Lin's CCC =.72-.94) and fed (Lin's CCC = .53-.80) appetitive states between visit 1 (V1) and visit (V2). Except for explicit liking fat bias, all primary outcomes were statistically consistent in fasted and fed states between V1 and V2. Changes in fat and taste biases in response to a standardized meal for all primary outcomes were also consistent between V1 and V2 except for explicit liking fat bias (Lin's CCC = .49- .72).

CONCLUSION

. The LFPQ-fr developed and tested in this study is a reproducible and reliable method to assess food reward in both the fasted and fed states in a healthy-weight French population.

Barriers to and Facilitators of the Consumption of Animal-Based Protein-Rich Foods in Older Adults: Re-Analysis with a Focus on Sustainability

Older adults may gain health benefits from the consumption of animal-based protein-rich foods, but environmental pressures suggest advocating some meat and dairy foods over others, and understanding the barriers and facilitators for consuming these different foods would be of value. Existing data on the barriers to and facilitators of the consumption of meat and dairy products were re-analysed for differing effects for white, red, and processed meat consumption and for yoghurt, soft cheese, and hard cheese consumption. White meat consumption was associated with fewer concerns over spoilage and waste and stronger perceptions that meat is convenient (smallest Beta = 0.135, p = 0.01), while red and processed meat consumption were positively associated with liking /taste, appearance, and convenience (smallest Beta = 0.117, p = 0.03). Yoghurt and soft cheese consumption were positively associated with liking/taste and medical concerns, and fewer concerns over ability and habit (smallest Beta = -0.111, p = 0.05), while hard cheese consumption was only associated with liking/taste (Beta = 0.153, p = 0.01). Taken together, these data suggest that enhancing or promoting the enjoyment, taste, visual appeal, and ease-of-consumption of the more sustainable meat and dairy options may be of value in encouraging the consumption of these foods in older adults.

Novel Liquor-Based Hot Sauce: Physicochemical Attributes, Volatile Compounds, Sensory Evaluation, Consumer Perception, Emotions, and Purchase Intent

Hot sauces are popular peppery condiments used to add flavor and sensory excitement to gastronomical preparations. While hot sauce occupies a retail category well over a century old, a novel production method using liquor as the base preservative rather than traditional vinegar is now commercially available, and its uniqueness begs study. Hot sauces produced with tequila, rum, vodka, and bourbon were compared to traditional vinegar-based hot sauces concerning physicochemical properties, volatile compounds, microbiological quality, sensory scores, emotions, and purchase intent (PI). Under accelerated conditions, pH, titratable acidity (TA), water activity (Aw), viscosity, and color were analyzed weekly for 20 weeks, whereas rheological properties, coliforms and yeasts and molds were examined on weeks 1 and 20. Hexyl n-valerate, butanoic acid, 3-methyl-, hexyl ester, and 4-methylpentyl 3-methylbutanoate were found in high concentrations in the pepper mix as well as the hot sauce produced with vinegar. When compared to vinegar-based hot sauces, liquor-based hot sauces had similar Aw (p > 0.05), higher pH, viscosity, and L* values and lower TA, a*, and b* values (p < 0.05). Samples formulated with liquors increased the relaxation exponent derived from G’ values having a greater paste formation when compared to vinegar-based hot sauces. The sensory evaluation was carried out in Honduras. The liquor-based hot sauces had a significant (p < 0.05) impact on emotion and wellness terms. Bourbon and tequila samples had higher ratings than control samples in several wellness and emotion responses (active, energetic, enthusiastic, good, curious, pleased, stimulated, and wild). Adventurous, joyful, free, worried, refreshed, and healthy scores were not significantly (p > 0.05) different among treatments.

Chili pepper preference development and its impact on dietary intake: A narrative review

A preference for chili pepper can be an acquired taste. The contrast between a chili lover and a hater illustrates the complexities involved in forming an appreciation for food that evokes a fiery pain sensation. This narrative review aims to understand the factors behind chili pepper preference formation across the life course and how individual chili pepper preferences can impact eating behaviors and dietary intake. This review was conducted using three databases, yielding 38 included articles. Results suggest five determinants of chili pepper preferences: culture, exposure, gender, genetics, and personality. Collective findings indicate that the strongest influences on preference acquisition include the individual environment from childhood to adulthood and repeated exposure to spicy flavors. With frequent exposure to spicy food, the perceived burn becomes less intense. Culture also influences exposure to chili peppers, with the highest consumption patterns seen within Mexico and some Asia countries. Additionally, males reported having a stronger preference for spicy foods than females. Twin studies illustrated that genetics influenced spicy taste preferences, underscoring the complexity of developing individual taste preferences. As for the impact of capsaicin-containing food on individual eating behaviors and dietary behaviors, appetite effects depend on the dose of capsaicin consumed, but three studies found a change in sensory desires for sweet and fatty foods after finishing a capsaicin-containing dish. Inconsistent results were reported for chili pepper's effects on hunger and satiety after consumption, but changes in specific food desires were observed. The impact of chili pepper on appetite and calories consumed was inconsistent, but the greater amount of capsaicin ingested, the greater the effect. Capsaicin's potential to be used for weight control needs to be further reviewed. In conclusion, evidence suggests that chili pepper preferences may be linked to innate and environmental aspects such as an individual's culture, gender, and genetics. Extrinsic factors like repeated exposure may increase the liking for spicy foods.

Adding Flavours: Use of and Attitudes towards Sauces and Seasonings in a Sample of Community-Dwelling UK Older Adults

Adding flavours can encourage food intake in older adults for health benefits. The use and attitudes of 22 community-dwelling UK older adults (15 females, aged 65–83 years) towards foods and products that add flavour, e.g., sauces and seasonings, were investigated. Participants used foods/products to add flavour when cooking and eating from 0 to 17 times/day. Taste and flavour were important, and foods/products could add flavour, make foods more pleasant and did not cause discomfort. There were concerns, however, over the healthiness of some foods/products, while consuming a healthy diet and one’s health were important. Reasons for adding flavours largely centred around ‘meal enhancement’, reasons for not adding flavours focused on ‘the product itself’ and ‘characteristics of the meal’, but there was ‘variation’ and many ‘individual differences’. Our findings highlight the benefits of adding flavours for food intakes, particularly the use of naturally flavoursome foods, such as herbs, spices, onion and garlic.

The organoleptic quality of liquid food formula made from snail (Pila ampullacea), tempeh, and moringa leaves

This study aims to determine the organoleptic quality of liquid food formula made from snail (Pila ampullacea), tempeh, and moringa (Moringa oleifera) leaves. The study was conducted in Yogyakarta, Indonesia. It involved 25 moderately trained panelists and also 5 trained panelists, who met the criteria. The measured variable was the organoleptic quality, which included aspects of color, texture, taste, and aroma. The formula tested was a powder formula made from the snail, tempeh, and moringa leaves. The proportion of snail flour, tempeh flour, and moringa leaves flour was 50:30:20. It was found that more than 50% of panelists liked the liquid food formula based on color, texture, taste, and aroma. Independent t-test to determine the difference between the organoleptic quality of the two groups showed p = 0.710 for color, p = 0.335 for texture, p = 0.603 for taste, and p = 0.880 for aroma. In conclusion, most of the panelists liked the liquid food formula products made from snail, tempeh, and moringa leaves based on the organoleptic quality result. There was no difference between the organoleptic quality studies of the two groups in the aspect of color, texture, taste, and aroma.

Effect of Alternative Preservatives on the Quality of Rice Cakes as Halal Food

The halal food market is steadily increasing. The use of alcohol for any reason is strictly prohibited in halal foods; however, ethanol is widely used as a preservative for commercial rice cakes (tteok). The purpose of this study was to investigate the use of natural substances as alternative preservatives for rice cakes. Four different solutions were tested: distilled water (control), ethanol, grapefruit seed extract (GSE), and a mixture of citric extracts and organic acids (MCO). We investigated the total plate count (TPC), yeast and mold counts, color, texture profile assays (TPA), and sensory evaluation. Significant reductions of 3.65 log CFU were observed in TPC in rice cake treated with MCO solution after 28 days of storage. However, mold and yeast counts were only reduced by ethanol treatment. Among the physical texture properties analysis, hardness was maintained for the 28 days in all samples. The total color difference values (ΔE) revealed no significant color changes in any rice cake compared to the controls. The ethanol-treated rice cake scored the lowest for overall preference and desired hardness.

Cross-Cultural Consumer Acceptability for Ethnic Fermented Sauce Products: Comparisons among Korean, UAE, and US Consumers

The present study investigated the drivers of liking ethnic sauces in a cross-cultural context. Experiments were conducted to understand the acceptance of salad dressings and dipping sauces developed from Korean fermented seasonings among consumers with different ethnic backgrounds, including: South Korean, United Arab Emirates (UAE), and American. The samples of interest included four types of salad dressings made from fermented soybean paste (doenjang) and four types of spicy dipping sauces made from fermented chili pepper paste (gochujang). The salad dressings were preferred by Korean and US consumers. Koreans liked the nutty-flavored salad dressings, whereas UAE and American consumers commonly liked the spicy type. There was a stronger cross-cultural agreement in liking dipping sauces rather than salad dressings. Both Korean and American consumers liked spicy dipping sauces that elicited a sweet taste. UAE consumers tended to prefer the less spicy dipping sauce samples. Consumers in all three countries generally liked spicy dipping sauces more than salad dressings. Cultural differences were observed between the responses depending on the presence and level of spiciness in the two different food types. For product development with ethnic fermented flavors or chili spices, the contextual appropriateness and consumer familiarity with the corresponding flavor should be taken into account.

Post-Ingestive Sensations Driving Post-Ingestive Food Pleasure: A Cross-Cultural Consumer Study Comparing Denmark and China

Culture is one of the main factors that influence food assessment. This cross-cultural research aimed to compare Chinese and Danish consumers in their post-ingestive drivers of Post-Ingestive Food Pleasure (PIFP). We define PIFP as a “subjective conscious sensation of pleasure and joy experienced after eating”. We conducted two in-country consumer studies in Denmark (n = 48) and in China (n = 53), measuring post-ingestive sensations and PIFP using visual analogue scale, for three hours following consumption of a breakfast meal. Key results revealed perceived Satisfaction, Mental, Overall and Physical wellbeing to be highly influential on PIFP in both countries. Moreover, Danish consumers perceived appetite-related sensations such as Satiety, Hunger, Desire-to-eat and In-need-of-food to be influential on PIFP, which was not the case in China. In China, more vitality-related sensations such as Energized, Relaxation and Concentration were found to be drivers of PIFP. These results suggest similarities but also distinct subtleties in the cultural constructs of PIFP in Denmark and in China. Focusing on Food Pleasure as a post-ingestive measure provides valuable output, deeper insights into what drives Food Pleasure, and, importantly, takes us beyond the processes only active during the actual eating event.

Texture Preferences of Chinese, Korean and US Consumers: A Case Study with Apple and Pear Dried Fruits

The present study aimed to understand the drivers of liking dried apple and pear chips with various textures among Chinese (n = 58), Korean (n = 58), and US (n = 56) consumers. The possibility of hedonic transfer from snack texture preferences to fruit-chip texture preferences was also investigated among Chinese and Koreans. Fourteen fruit-chip samples with four textural properties (crispy, puffy, soft, and jelly-like) were selected. Consumers rated their level of liking for each sample, and then they performed hedonic-based projective mapping with the same samples. In the hedonic texture transfer investigation, consumers rated their acceptance of nine snacks with various textures but possessing similar textures to those of dried fruit samples. The data were analyzed by ANOVA and multiple factor analysis. Most consumers disliked samples with a soft or jelly-like texture, while liked samples with a crispy texture. Cross-cultural differences were observed in the liking of puffy samples, with both Chinese and Koreans liking puffy samples as much as crispy ones for their melting characteristics in the mouth, while US consumers perceived the puffy samples as being Styrofoam-like and disliked them. Hedonic transfer was observed from snack texture preferences to fruit-chip. Individual texture preferences for snacks seem to significantly affect the texture preferences for fruit chips.

Understanding the drivers of liking for fresh pears: a cross-cultural investigation of Chinese and Korean panels and consumers

BACKGROUND

This study identified and compared the drivers of liking for fresh pears cross-culturally, using Korean and Chinese panels and consumers. The pear samples consisted of six types of fresh pear varying in flavor and texture qualities. The descriptive panels for the two countries independently derived descriptive terms for the pears. Acceptance testing was also conducted to examine the hedonic levels of fresh pears among Chinese and Korean consumers. Multivariate analysis of variance, using a general linear model (GLM), and multiple-factor analysis were applied to the descriptive data. The consumer test data were analyzed using a GLM, correspondence analysis, and internal preference mapping.

RESULTS

The results showed that the overall perceptual configurations of pears developed by the Chinese and Korean panels were similar. The consumer liking for fresh pears and the drivers of liking were also cross-culturally similar. Consumers from both countries liked crisp and juicy Asian pears but they had different perceptions of and liking for the pear with a strong fruity note and soft texture. This observation was supported by the results of the descriptive analysis, which showed that the Chinese panel considered this pear sample to be fruity and have an harmonious flavor, whereas the Korean panel - which was less familiar with the sample - considered its flavor unharmonious.

CONCLUSION

Previous cross-cultural studies have often found that food acceptance levels vary markedly with the degree of familiarity with target foodstuffs. However, unlike other food categories, the difference seems relatively small for fruits that are commonly available across cultures. © 2019 Society of Chemical Industry.
