This study classified five types of online food subscription economy: replenishment, curation, surprise, membership, and visitation. An online survey was conducted with 314 customers who experienced 5 types of online subscription economy. This study selected the characteristics of the food subscription economy as convenience, perceived personalization, economic utility, and timeliness through previous studies. The effect of the four characteristics on perceived value (utilitarian and emotional) and the relationship between customer engagement and perceived value, which are dependent variables that have never been used in the food subscription economy, were verified through the S-O-R model. In this relationship, we demonstrated how consumers' personal tendencies, such as need for cognitive closure and self-efficacy, mediate between timeliness and perceived value related to online food delivery. The study results are as follows. Perceived personalization, convenience, and timeliness had a positive effect on the utilitarian value in the order. It also had a positive effect on emotional values in the order of perceived personalization and timeliness. On the other hand, economic utility had no significant effect on practical branches. Customer engagement had a positive effect in the order of emotional value and utilitarian value. The lower the need for cognitive closure the more positive the utilitarian value. The lower the self-efficacy, the more positive the emotional value was perceived. Through the above study, companies that want to operate or start an online food subscription economy need a strategic approach rather than unreasonable price discounts in pricing policy. In addition, it is necessary to focus on marketing activities that provide emotional value by focusing on perceived personalization, which is the satisfaction factor of online food subscription.

This study was conducted to investigate the eating patterns of Korean men by analyzing the relation among their socio-demographic characteristics, value toward food and nutrition, and eating behavior. Nine hundred twenty nine Korean men were selected by the stratified random sampling method. The socio-demographic characteristics of the subjects had a significant influence on their value toward food and nutrition. After in their sixties had meals for physiological needs rather than for nutrition or preference. Highly educated people, professional workers, office workers and people in the higher incomes, placed a higher value toward food and nutrition. In addition, rural inhabitants had a significantly lower value toward food and nutrition. They mainly ate to satisfy their hunger. The subjects' eating behavior had a significant difference according to their socio-demographic characteristics. The aged and the less educated valued breakfast the most, and showed a preference for rice as the staple food. The rate of skipping meals for this group was low. The higher their income, their eating behavior score was equally high, while the primary industrial workers and rural inhabitants had a low eating behavior score. Value toward food and nutrition had a significant influence on eating behavior. Those that placed a high value toward food and nutrition showed a marked tendency to choose bread or noodles rather than rice. In addition, those who placed a high value on food and nutrition skipped fewer meals and had a higher eating behavior score.

The purpose of this study was to investigate the effects of perceived price and servicescape on employee service quality, food and beverage quality, and customer value in Daegu Korean restaurants and to suggest methods for them to become the food mecca of Korea and the world. The samples for this study were customers of nine Korean restaurants in Daegu. A total of 368 questionnaires were analyzed with factor analysis, a reliability test, and a covariance structural analysis. The results showed that perceived price was positively related to employee service quality and food and beverage quality and that servicescape was positively related to employee service quality and food and beverage quality. However perceived price, servicescape, employee service quality, and food and beverage quality were not related to customer value. The reasons were that these factors did not influence perceived customer value in Daegu Korean restaurants. The Daegu municipal office should require these restaurants to develop distinguished employee service and food and beverage quality and conduct consistent marketing to Koreans and westerners, so that these restaurants can become the food mecca of Korea and the world.

A total of 284 milled rice (MR) marketed in Korea were analyzed for grading characteristics (head rice, broken kernels, chalky kernels, and damaged kernels%), color characteristics (L-, a-, b-values, and whiteness), protein content (%), and the cooked rice (CR) sensory quality to investigate the key characteristics affecting the overall sensory quality of rice marketed in Korea. Relatively high correlation with the overall sensory quality of the CR was found in color characteristics such b-value of the CR (r=-0.779) and MR (r=-0.545), the a-value of the CR (r=0.513), and the whiteness (r=0.298) of the MR, compared to protein (r=-0.150), and the moisture (r=0.158) contents of the MR and the percentage of head rice (r=0.195). Partial least squares (PLS) regression of the CR b-value with various characteristics of the MR showed that CR b-value was increased with MR b-value effectively, followed by protein content, damaged kernels, chalky kernels, and colored kernels of MR while it was decreased with whiteness and moisture content for the MR.

The home meal replacement (HMR) food industry began in 1980, and it has grown rapidly as a major food business for both consumers and the food industry since the development of industrialization and societal changes. Many researchers investigated a variety of HMR food product characteristics. On the other hand, previous studies have focused only on topics in limited study areas. Therefore, this study examined the effect of color marketing and the value of experience on the consumer behaviors. This study used a survey to collect the respondents' opinions about HMR food products. The study results showed that the characteristics of color marketing and the experience value of the HMR products influenced the consumers' attitudes. Moreover, consumers' attitudes affected their repurchase behavior. The results suggest that marketers of HMR food products should use colors that show the characteristics of products to appeal to consumers. In addition, HMR products should be developed in line with what consumers value the most; for example, consumers value their previous experience with the products and the characteristics of the products.

This study was conducted to examine the effect of globalization of Korean food according to well-being value perception and the foreign visitor Korean food experience. An analysis of variance and a linear regression analysis were conducted to analyze the hypotheses. The findings are summarized as follows: (1) The most important quality when eating Korean food was "taste" (37.3%). (2) The most important well-being value recognition items for Korean food were "kimchi" and "bulgogi". "Bibimbap is well-being food" (3.82 points) and "Korean food is healthy because it consists mainly of cereals and vegetables" (3.56 points). (3) The subjects highly recognized the "improvement in service quality of Korean restaurants" (3.59 points) with regard to the importance of a globalization strategy for Korean food. (4) High-intake Korean foods were "bibimbap", "baechookimchi", "galbigui", "pajeon", and "bulgogi", in that order. In contrast, the intake frequency for "songpeon", "sikhei", and "guksu" was very low. (5) The subjects thought that the globalization possibility for Korean food was high, as foreigners ingested a lot of baechookimchi. (6) The most effective well-being value recognition item for globalizing Korean food was "Korean food is nutritious and good for the health" followed by "I have much interest in Korean well-being food". and "Korean food is a well-being food because it contains many fermented and seasonal items", in that order. (7) The most effective food for globalizing Korean food with a high-intake frequency was "baechookimchi", followed by "galbigui", "guksu", and "bibimbap".

The objectives of the present study were to assess the oxidative stability of South Korean n-3 (omega-3 fatty acid) supplements carried out from 2018 to 2019 and evaluate the influence of product characteristics on oxidative safety. A total of 76 n-3 supplements were analysed for oxidation safety by four markers, including acid value (AV), primary oxidation (peroxide value, PV), secondary oxidation (p-anisidine value, pAV) and total oxidation value (TOTOX). Among the supplements tested, 5.3 %, 55.3 %, 28.9 % and 46.1 % exceeded the international voluntary recommended levels for AV, PV, pAV and TOTOX, respectively. Purity (%) of products, remainder of expiration date (suggested shelf life), package in press through package (PTP) and products with additives had statistically significant differences oxidation assessment levels (p < 0.05). In addition, n-3 group found in Algae oil had significantly lower AV levels than the group that did not, and product with Alaska pollack oil, had significantly higher pAV levels than without group (p < 0.05). The high oxidation status of South Korean n-3 products in the present study could not be considered a public health problem right now. However, the levels of oxidation may affect a lot the efficacy and safety of using n-3 supplements. Thus, current oxidation safety limits should be reestablished by regulatory bodies to ensure the safety and efficacy of n-3 supplements, so that the standards could be applied to the products available to consumers.
