This study analyzed the factors affecting visual attention toward sugar-reduction information (SRI) on sugar-reduced beverages (SRBs) and identified the most optimal SRI type and location using eye-tracking. The eye-tracking results were compared with those of a self-reported questionnaire.

An eye-tracking experiment was conducted on 50 Korean people in their 20s and 30s to analyze implicit responses. Subsequently, a self-reported questionnaire was administered to analyze explicit responses, facilitating the investigation of perceptions, attitudes, preferences, intentions to purchase SRBs, and preferred SRI types and positions.

The results were as follows. First, personal trait-, state-, and product-related factors were found to affect eye movement in relation to SRI. Second, eye-tracking revealed that SRI types and locations that drew long-lasting fixation and attracted considerable attention were similar to those preferred in the self-reported questionnaire. Therefore, to efficiently convey information on SRBs, SRI should be combined with a graphic, and not merely a word, and placed in the upper-right corner, exhibiting consistency with the results of two previous experiments.

This study specifically focused on considering personal and product-related traits while conducting an eye-tracking experiment to investigate the factors that attract consumers' attention. Furthermore, this study is the first to investigate the use of SRI labels to promote SRB selection. What is significant is that both explicit and implicit responses were assessed and compared via a self-reported survey and eye-tracking experiments for various SRB categories.

As the risks associated with sugar-sweetened beverages (SSBs) increase, various policies require sugar to be reduced in beverages. This paper segmented consumers according to food-related lifestyle (FRL), analyzed beverage selection attributes and preference for sugar-reduced beverages (SRBs) for each group and presented basic data for the strategies of SRBs for each consumer group.

In total, 1,000 Korean consumer panels responded to the online survey. The questionnaire consisted of FRL, beverage selection attributes and attitude toward SRBs.

Consumer groups were divided according to FRL: rational, value seeking and careless consumer. Rational consumers tended to be in their 30s or 50s and women, and they focused on product quality/hygiene when choosing beverages. Value seeking consumers were mainly in their 40s and 50s and were characterized by high education and income. They showed high scores in quality/hygiene, economy and sensory traits. Careless consumers were more likely to be in their 20s–30s, unmarried men and considered sensory traits as the most important factor.

The main limitation of this study is the lack of generalization of consumer panels to represent the entire population because they were part of an online research firm.

This study implies that segmenting consumers according to FRL allows detailed analysis of consumer attitudes and behaviors. Using this analysis, the complex consumer pattern can be used as basic data for promoting sugar-reduced beverages.

The purpose of this study is to segment Czech consumers based on their sustainable food consumption and their relationship with listening to music. Specifically, the authors attempt to answer the following question: is the relationship to music a segmentation difference for young consumers in the case of sustainability? The food-related lifestyle (FRL) concept is used as a framework; little attention has been paid to the FRL profile in the context of certain types of consumer orientations toward sustainability as a social value among consumers in Czechia.

In this research, the authors used 22 items related to sustainability (identify sustainability-oriented and health-oriented variables and socially and ethically oriented variables). The statistical data analysis techniques included factor analysis and cluster analysis. The results of the cluster analysis are the market segments. The total sample consists of 331 university students from Czechia. These data are from a continuous research project. A factor analysis identified six factors with satisfactory reliability coefficients. Using factor scores, a cluster analysis was run, resulting in four segments. These segments were further analyzed and described toward their sustainability orientation.

FRL concept was used to evaluate whether there are differences in the profiles of consumer orientations. Results emphasize the importance of personal characteristics and attitudes toward music, which in turn affect strategies to communicate with different segments to promote sustainable foods. Each segment has statistically significant differences in terms of its FRL.

This study explores the link between attitudes and behavior and suggests strategies to better understand the effect of information on consumer behavior. The results can help practitioners develop labeling strategies for fair-trade and sustainable foods to better focus on specific segments of consumers. This can be relevant when a sustainable food market is just starting, but hopes to reach more maturity in Czechia should be of the utmost importance for investors making long-term investments.

The authors propose a dairy bundle, integrating strategies to jointly maximise producer revenue and consumer utility according to the latter's preferences.

An algorithm based on a nested logit model identifies the bundle maximising producer revenue based on factors affecting consumer purchase behaviour. The data are drawn from a mall-intercept survey administered in Iran, with consumers stating a hypothetical choice among a comprehensive set of dairy products.

Demographic characteristics and marketing mix elements significantly affect consumers' preferences. An algorithm based on the estimated dissimilarity parameter determines the best bundle of dairy products, simultaneously obtaining the highest utility and the highest expected revenue.

Consumer preference and maximum producer or retail seller income are considered simultaneously. The bundling promotion strategy is widely used for food offerings and fresh foods and can be extended to other products.

This study develops a modified food-related lifestyle (FRL) instrument to analyse Kosovo consumers' fruit consumption behaviour and attitudes.

The research study is based on a structured questionnaire designed using a reduced version of the FRL instrument, including evaluation factors related to fruit consumption, which is useful to describe a fruit-related lifestyle. Data were collected through a face-to-face survey with 300 consumers in three main cities in Kosovo. A principal component analysis (PCA) with Varimax rotation and Kaiser Normalisation was performed to interpret and investigate fruit-related lifestyles. Cluster analysis was performed to analyse market segments, using the identified factors obtained from the PCA, a hierarchical clustering algorithm with a Ward linkage method and the K-means clustering technique.

Consumption behaviour is motivated by health concerns (perceived), fruit (nutrition) content and consumption habits. Four distinct consumer clusters were identified based on the fruit-related lifestyle instrument and analysed considering the different fruit purchase and consumption behaviour, attitudes towards health, quality, taste and safety.

The authors adapted a survey tool based on a reduced FRL instrument to elaborate a specific survey instrument suitable to describe the fruit-related consumer's lifestyles. The instrument was not designed according to the standard scales design procedure, but it is a first step towards creating a fruit-related lifestyle instrument.

The fruit-related lifestyle instrument can be used in studies focused on fruit consumer segmentation. Results provide insight into fruit marketing and distribution companies, which can adjust their marketing strategies and customer-oriented initiatives tailored for specific consumer segments. Results can be useful also for policymakers to promote increased fruit consumption.

Prevention of chronic diseases by means of dietary modification can be achieved by consuming healthier foods with lower sugar content. However, reducing sugar content causes significant impact on the sensory quality and consumers’ acceptance towards local healthy products. This study aims to evaluate the effects of cross-modal interactions of Aroma-Taste-Texture (ATT) in yoghurt drink.

Fifteen sugar reduced yoghurt drinks [S, sugar percentage (0%, 2%, 4%); T, stevia dosage (0%, 0.01%, 0.02%); P, pectin dosage (0%, 0.3%, 0.6%)] based on ATT were evaluated by 300 consumer panellists on aroma, taste, texture and overall acceptability on a nine-point hedonic scale while sweetness intensity was measured using a seven-point just-about-right (JAR) scale. Interactions between ATT were determined.

Significant interaction was found between sugar and stevia, with F14 (4S0.02T0P) rated as sweeter than F4 (0S0.02T0P) (p = 0.003) and higher overall liking score than F11 (4S0T0P) (p = 0.001). Similarly, significant interaction was found between sugar and pectin, with F2 (0S0T0.6P) rated as significantly lower overall liking score and less sweet than F1 (0S0T0P) (p = 0.0001). Likewise, significant interaction was found between stevia and pectin, with F2 (0S0T0.6P) rated as significantly lower overall liking score and less sweet than F1 (0S0T0P) (p = 0.0001). Overall, F5 (0S0.02T0.6P) scored highest in overall liking and closest to the ideal sweetness (JAR = 4) indicating the possibility to apply 100% sugar replacement.

Application from the present study could be great potential solution in developing healthier range products while meeting consumer preference. The present study concluded that interactions of ATT of yoghurt drink will induce desirable changes in sensory and sweetness perception.

As a basis for development of new, and rationalisation of existing products, consumer preferences in commercial filter coffees were examined in a quantitative approach with multivariate mapping. Coffees were brewed from 12 ground bean blends and served to 150 consumers as drunk normally – black, whitened and/or sweetened. In a complete block design with two sessions of six coffees, employing randomisation to reduce order effects, hedonic data on a five‐point scale were collected then processed using Q‐mode principal component analysis yielding preference maps for each presentation. Conventional descriptive profiling provided information on blend characters allowing soft modelling to determine sensory attributes driving preference scoring. From univariate data analyses, gender was a significant factor for presentation style: addition of milk increased preference scores for blends in males and sugar reduced preference ratings for females. The outcome was a series of consumer segmentations for different coffee presentations.

One of the major technological changes in food products over the last decade has been the development of “lite” food and drinks. These products have become regular items of purchase and acceptance in UK diet. The principal areas of growth in the “lite” market have been in sugar‐free drinks and low fat foods. Whilst market growth has been stimulated by increased consumer awareness of diet and nutrition, consumers are being influenced by the image message associated with such products rather than a strict health message. Harmonisation of European food law after 1992, especially in respect of sweeteners, offers potential opportunities for further growth in “lite” markets. Fat replacers are likely to provide an area of future interest as long as concerns about the mass marketing of synthetic foods do not dampen the market.

The present study was carried out to standardize the method for preparation of naturally carbonated fermented paneer whey beverage by incorporating pineapple and strawberry fruit juice and to check their suitability in the beverage by evaluating the organoleptic characteristics and shelf life of product.

Beverage was inoculated with yeast culture Clavispora lucitaniae at 0.5 per cent v/v and fermented at 35 ± 1°C for 36 h aerobically. Standardization of total soluble solids (TSS) (16, 15, 14, 13 and 12oBrix) and juice concentration (15, 20, 25 and 30 per cent) of beverage was done on the basis of organoleptic evaluation, and the beverage with TSS 12oB and 30 per cent juice was selected best for further storage study. Two types of beverages were prepared: paneer whey beverage blended with pineapple juice and paneer whey beverage blended with strawberry juice, and were stored at refrigerated (4 ± 1oC) and ambient (25 ± 5oC) conditions. Effect of storage on physico-chemical, microbiological and sensory attributes were studied periodically after every 15 days for 90 days of storage period.

There was significant decrease in brix:acid ratio (p = 0.0008) from 12.0 to 9.3, total sugar (p = 0.017) from 10.8 to 6.8, ascorbic acid (p = 0.002) from 17.8 to 9.3 mg/100 mL and lactose (p = 0.037) from 3.1 to 0.6 per cent content over 90 days of ambient storage period. Total yeast count increased during the initial stages of fermentation and started declining after 60 days of storage. The alcohol production started after 15 days and reached 0.7 per cent after 90 days for paneer whey beverages blended with strawberry juice. The more variations were found in the physico-chemical and microbiological properties of the beverage at ambient storage than refrigeration storage. Highest score for color, flavor, mouthfeel and overall acceptability was found on third days, which decreased further during the storage. The comparative study of the paneer whey beverage blended with strawberry juice stored at ambient and refrigeration temperature showed that maximum decrease was found for score of appearance/color, flavor, mouthfeel and overall acceptability at ambient temperature as compared to refrigeration temperature. Beverage stored at refrigeration temperature was found more acceptable than the beverage which was stored at ambient temperature irrespective of all types of beverages.

The refrigerated beverage was found more acceptable up to 90 days, whereas beverage stored under ambient conditions was found acceptable up to 60 days. The products so obtained had naturally produced CO₂, and little alcohol content added effervescence, sparkle, tangy taste and flavoring characteristics.

The purpose of this paper is to identify segments of Mexican consumers with regard to their motives for food choices.

A questionnaire based on the Food Choice Questionnaire was applied to 1,202 consumers. A factor analysis and a cluster analysis were performed on the data.

Ten factors were identified: care for weight and health, social sensitivity, practicality, economic aspects, non-industrialized, hedonism, traditionality A, familiarity, traditionality B, and no added sugar. Resulting clusters were named as: traditional, healthy, conscious, and careless. Statistically significant differences (p<0.05) were found due to gender, age, marital status, and educational level, but not for body mass index. There are signs of different consumers, but it seems that Mexican consumers in general express low sensitivity to issues of health and nutrition, even more so towards animal welfare and products that are friendly to the environment.

The large diversity of motivations and behaviours in food consumption in Mexico are not all addressed in this study. However, this work opens a new area of research in Mexico so that in the near future studies on the diversity of Mexican consumers are undertaken, looking at the transformation of their food preferences.

In Europe, governments have addressed the new forms of consumption taking advantage of opportunities that benefit local producers, through the generation of added value as “Protected Designations of Origin (DOP)”, geographical indications, collective brands, ecological produce, local products of the land, among others. These proposals are promoted as a path to follow in Latin America, assuming that Latin American consumers have the same characteristics or interests as in those developed countries. But, not knowing consumers motives of preference represents a problem in the processes of valorization of food products.

Economic development, demographic, and sociocultural changes in Latin America have promoted phenomena both in the polarization of livelihoods in their societies as well as changes of lifestyles in different social strata. Therefore, studies are needed on the effect of these changes not only in food consumption, but also on the symbolic elements when consumers choose their food.

In Mexico, the study of food consumption has followed diverse approaches, as a matter of policy, from an economic perspective, from anthropology, particularly focussed on indigenous cultures, from the nutrition and health field or emphasizing economic aspects. As in other developing countries, those works do not address the role of the consumer and their motivations, so that research that studies their motives in the choice of foods is needed.
