Consumer perception of balsamic vinegar: A cross-cultural study between Korea and Italy
Graphical abstract
Introduction
Since there is an evidence that traditions, beliefs and values are among the main factors affecting preference, mode of food preparation, serving and nutritional status, it seems that culture is a major determinant of food choice (Cox, 2007, Chap. 16). Therefore, investigating cross-cultural dimensions of food choice is a key issue of food research in order to understand consumer behaviour in different countries (Prescott et al., 2002, Tu et al., 2010). Cross-cultural factors affecting food choice are several, some related to language and the way language drives focus of attention, while others have social origin, whereas others referred to focus on attention and perception (Risvik, Rødbotten, & Olsen, 2007, Chap. 13).
Various studies have been conducted to explore the perceptual differences between consumers of different culture. Kim, Jombart, Valentin, and Kim (2013) observed that the sensory properties of the green tea samples were the main factor in Napping® for consumers who were familiar with the products. They indicated that the Korean consumers who were more familiar with green tea, discriminated the green tea samples more clearly depending on the processing methods and elicited more terms to describe the products than the French consumers. Importance of familiarity on food perception also has been emphasized in the study comparing perception of perilla between Korean and Italian consumers. It was indicated that familiarity played an important role in the perception of perilla (Laureati, Pagliarini, Bassoli, & Borgonovo, 2014). However, in a cross-cultural study (Blancher et al., 2007) between French and Vietnamese consumers examining the difference in description of texture characteristics of jellies, it was found that French consumers described more terms than Vietnamese consumers even though Vietnamese consumers were more familiar with the products
In order to increase the knowledge on the cultural difference of food perception, in this study we have investigated the cross-cultural differences of food perception between Italian and Korean consumers using balsamic vinegar which is a traditional Italian product. The term “balsamic vinegar” is generally adopted to identify sauces, condiments and dressings with particular sweet taste. Since the vinegar is used as a condiment for foods or as an ingredient in dishes by the consumers, the quality of the product is primarily determined by its sensory properties as it may modify the overall liking of a given food or meal (Tesfaye, Morales, Garc, & Troncoso, 2002). The possible variability in ingredients and aging time gives rise to a high number of balsamic vinegars differently produced in several countries around the world. In Italy, two types of balsamic vinegar products are available: the “traditional balsamic vinegar”, made using an artisanal production process; the “balsamic vinegar of Modena”, produced on industrial scale with a modern production process. Several samples belonging to these two categories and other balsamic vinegar from other countries (Korea, Germany and Spain) were used in this work to include a variety of samples.
The consumers' perception of the balsamic vinegar samples were investigated by means of the sorted napping method (Pagès, Cadoret, & Lê, 2010), a rapid and cost-effective technique which is a natural extension of the Napping® method. In comparison to Napping®, sorted napping has the advantage to collect information on how consumers group the products and describe the product groups created. Our aim was to verify if the sorted napping was effective in showing cultural differences in grouping the samples and describing the product groups between Italian and Koreans. To evaluate the ability of the consumers in describing balsamic vinegar, sorted napping data were compared with descriptive data obtained in this study from a Korean panel of trained assessors and with descriptive data from a panel of Italian trained assessors reported in literature. Moreover, data on consumers' familiarity with balsamic vinegars and food matching data were collected. Even if a clear theoretical background for familiarity is not available in literature, our hypothesis was that a different level of familiarity with the product could differently impact on product description ability and food pairing choices. In summary, the specific aims of the present work were: 1) to compare the consumer perception of various balsamic vinegar products in Italy and in Korea using the sorted napping method; 2) to explore a potential relationship between product sensory attributes and familiarity expressed by Italian and Korean consumers; 3) to explore a potential influence of familiarity with balsamic vinegar on product description ability; 4) to investigate the effect of the Italian and Korean gastronomic culture on the selection of food paired with balsamic vinegar.

Balsamic vinegar samples
In order to explore the sensory perception of Korean and Italian consumers, nine commercially available balsamic vinegars were selected. They were differed in aging time, production method, country of origin, and ingredients. The information of the 9 balsamic vinegar products used in this study is given in Table 1. The products were purchased form a local market in Seoul (Republic of Korea) and transported to the University of Gastronomic Sciences by airplane, except for the two traditional
Product map
Fig. 1 shows the graphical representation obtained by applying the FASNT function to the sorted napping data for Korean consumers. The first three principal dimensions of the map accounted for 55.94% of the total variance: 27.22%, 16.13%, and 12.59% for Dim1, Dim2, and Dim3, respectively. The balsamic vinegars were largely separated according to their production processes. The first dimension separated the two samples produced using the traditional method (I25T and I12T) from all of the other
Discussion
The similar product configurations obtained from the sorted napping performed by the Koreans and Italians showed a similar product discrimination capability between the two groups of subjects. Comparing the two consensus maps in Fig. 1, Fig. 2 that were obtained from the sorted napping task reveals that both groups of consumers separated the Korean product from the rest of the modern-style vinegars and easily discriminated the two traditional balsamic vinegars from all of the other samples.
Conclusions
This study investigated the sensory attributes of various balsamic vinegar products in a cross-cultural context. The results obtained revealed that sorted napping effectively showed cultural difference of balsamic vinegar perception between Korean and Italian consumers. In fact, several perceptual differences were observed between the two groups of subjects, in both grouping the samples and describing the product groups. In particular, the choice of the attributes was specifically related to

2020, Food Quality and PreferenceCitation Excerpt :Thus, it seemed extremely relevant to investigate the potential of jellyfish in food pairing, particularly for the Italian population. Indeed, even if food pairing was defined as by the standard concept that ingredients with similar flavor constituents taste well when combined in a recipe (Blumenthal, 2008), different dietary cultures may have different concepts of food pairings: thus, food pairing is likely a culturally- (and cuisine-) specific process (Lahne, 2018; Torri, Jeon, Piochi, Morini, & Kim, 2017). Ahn, Ahnert, Bagrow, and Barabási (2011) found that Western cuisines show a tendency to use ingredient pairs that share many flavor compounds, whereas East Asian cuisines tend to avoid compound sharing ingredients.
Consumer perception and use of nopal (Opuntia ficus-indica): A cross-cultural study between Mexico and Brazil
2019, Food Research InternationalCitation Excerpt :Several cross-cultural studies have been conducted in this context, such as a research evaluating the rice consumption among Korea, Japan, Thailand and France (Son et al., 2014); the relationship between food and well-being among France, Portugal, Spain, Brazil and Uruguay (Ares et al., 2015); the consumption of beers between Mexico and France (Gómez-Corona et al., 2016); concepts associated with soy milk among Korean, Chinese and Western consumers (Kim, Petard, & Hong, 2018) and consumers' perception of balsamic vinegar between Korea and Italy. Therefore, understanding the intercultural differences in food perception is a fundamental issue, since it allows us to understand consumer behavior in different countries (Torri et al., 2017). The consumer acceptance of foods that are not inserted directly in the food context of a certain population reflects different perspectives for the same object of study that refers to historical, geographic, climatic and cultural factors that directly influence the affective and cognitive interests of the population (Son et al., 2014).
