This study investigated the quality characteristics of madeleines prepared using varying amounts of roasted black soybean flour (RBF). The RBF was used to substitute 0% (control group), 20% (RBF-20 group), 40% (RBF-40 group) and 60% (RBF-60 group) of weak flour (WF) in the manufacture of madeleine. The substitution of WF with RBF showed decreased the pH but increased the sugar concentration of the batter (p<0.01). Low lightness (L) and low yellowness (b) were observed in the experimental groups at high ratios of RBF substitution (p<0.05). The experimental groups of madeleines showed higher hardness and chewiness than the control group (p<0.001). The principal component analysis of the RBF-60 experimental group, which had the highest proportion of RBF, showed that it had relatively strong characteristics with respect to "darkness", "soybean odor", "sesame odor", "grains odor", "savory flavor", "sweetness", "black soybean taste", and "moistness". The acceptance test results, showed that the RBF-20 experimental group was similar to the control group with respect to "odor acceptance", "taste acceptance", and "texture acceptance". Thus, this study confirmed the possibility of using RBF for the preparation of madeleines.

Recently, as demand for delivery services has increased rapidly due to COVID-19, the food service O2O(Online to Offline) platform has also grown significantly. This study aimed to verify the influencing factors on continuance use intention of O2O platform using the Information Service Success Model and Post Acceptance Model. An online survey was conducted on 379 consumers who used the food service O2O platform in the past six months, and the collected survey was analyzed using SPSS 26.0 and AMOS 24.0. As a result of the verification, in the influence relationship between the Information Service Success Model and Post Acceptance Model, system quality was found to have an effect on perceived usefulness, but information quality and service quality were rejected for perceived usefulness and were partially adopted, The rest were all found to have a significant effect. In the moderating effect according to the amount used, the intention to continue using was stronger when the group who spent more than 30,000 won was satisfied. These results support previous research on O2O platforms and provide academic implications as well as practical implications for practitioners in the food service industry.

A survey was conducted to examine the knowledge and acceptance of food irradiation in order to provide baseline data required in the development of food irradiation education programs for college students. 150 students majoring in food and nutrition or food technology in the Chungnam National University were chosen for a survey. The results are as follows. First, college students' knowledge about food irradiation is scanty. Knowledge assessment showed that 56% of the participants had previously heard of food irradiation. 68% of the respondents thought that radioactivity remains in food after irradiation and 25.3% of them were not sure whether radioactivity remains in food after irradiation or not. Only half of the respondents thought that nutrient loss due to irradiation is equal to or lower than that due to cooking or freezing. Second, approximately 56% of the respondents showed that food irradiation is somewhat or strongly needed for meat or fish; whereas, over 60% of them showed that food irradiation is not needed for grain, vegetable and fruit. Almost 40% of the respondents were seriously concerned about irradiation of vegetables and fruits; whereas, they showed less concern about spice irradiation. More than half of the respondents were not willing to use irradiated food in all the six food groups. Third, the correlation analysis showed that the need of food irradiation is negatively correlated with concerning about the irradiated fish and fruits, but positively correlated with willingness to use irradiated food in all the five food groups, except in spices. Concern about the irradiated food is negatively correlated with willingness to use irradiated food from all the six food groups. Fourth, almost all the respondents (over 90%) agreed that the irradiated food labeling is required as well as the development of proper methods to identify irradiated foods.

Based on the safety of irradiated foods which was demonstrated from the toxicological, microbiological and nutritional points of view, irradiation has been identified as a viable technology for food preservation and processing, having a potential both of reducing storage losses by controlling spoilage organisms, sprouting and ripening, and of improving hygienic quality of raw and processed products. Research and development over decades in the field of food irradiation have led to the regulatory approval in 37 countries and of them 25 countries including Korea are commercially utilizing food irradiation process. Although progress towards acceptance of food irradiation by the industry is slow, actual market trials have shown that once consumers have understood this technology, they are willing to buy irradiated foods. Considering recent advances in food irradiation and restrictions in the use of chemical fumigants, it is expected that food irradiation is in the process of "taking off". This paper deals with up-to-date progress in food irradiation with particular reference to domestic activities in legislation, consumer perception, commercialization, and potential applications in the food industry.

In this study, we compared the differences and similarities between the Korean food culture and the Vietnamese food culture by surveying food resources and researching the process of Korean food being accepted into Vietnam. We suggest countermeasures for advancing Korean food into Vietnam. We conducted in-depth interviews regarding Korean food with Vietnamese food specialists who ate Korean food. As a result, Vietnamese foodies eagerly recognized that the most representative thing about Korean food was the special properties of its various and affluent side dishes. They were also aware of kimchi, made of various vegetables and condiments, as an excellent side dish compared to the Vietnamese who's staple is boiled rice. Furthermore, the flavor of Korean food was preferred by the Vietnamese who were familiar with foods such as Neue-ok-mom or fermented seafood. It was thought that the new food could be eaten with many vegetables. The specialists replied that the most typical functional property of Korean food was health. The acceptance process of Korean food into Vietnam was based on the acculturation theory. That made the Vietnamese easily experienced strange culture in the case of propagation by whom have already experienced, through the selective filter steps by various images of Korea, and made them accept the Korean food through temporary choose and acceptance step such as recommendations by friends. Globalization strategies for Korean food proposed by the Vietnamese foodies were public relations marketing in voluntary contact environments, distinguishing traditional Korean foods through research and development, and globalization by diversifying the Korean restaurant concept.

The present article covers a brief introduction on how repeated exposure design can be utilized for developing new food products. A generic consumer taste test which measures consumer acceptance in one trial may have limitation in predicting long-term acceptability of a product. The article describes the changes in food preference and choice during the course of life from infants to elderly. Then, several possible theories that proposes to delineate the underlying mechanisms for acquiring the liking for food is introduced. The article also discusses general experimental design, case studies which adopted repeated exposure design, the limitations and rapid test methods to predict long-term acceptance.

Purpose: This study investigated the quality characteristics of Jeungpyun prepared with brown rice and sea tangle powder. Methods: The pH, volume, and spreadability of the dough and moisture content, color, texture and sensory evaluation of the Jeungpyun were performed. Results: The results showed that the pH of the dough decreased in all sample groups with the lapse of fermentation time, and ultimately revealed a pH ranging from 4.55-4.65. The spreadability of the dough significantly decreased as the substitute amount of the brown rice flour increased; the sample group with 1% sea tangle powder showed a significantly larger spreadability than the sample group with 2% sea tangle powder (p<0.05). The moisture content in the Jeungpyun showed a significantly lower result as the substitute amount of brown rice flour increased (p<0.05). Lightness (L) was reduced as the substitute amount of brown rice flour increased, and redness (a) and yellowness (b) also appeared to increase. As a result of measuring the texture, the 50% sample group with a high substitute rate of brown rice flour was observed to have high characteristics of hardness, gumminess and chewiness, and was low in cohesiveness. The result of the acceptance test showed that the sample group that substituted 25% brown rice flour and added 1% sea tangle powder was evaluated to have a significantly higher acceptance than the sample group that added 2% sea tangle powder in terms of color, texture and overall acceptance. Conclusion: The result of the acceptance test showed that the sample group that substituted 25% of brown rice flour and added 1% of sea tangle powder showed higher tendency in all acceptance attributes than the sample group that did not substitute the brown rice flour to show the possibility of developing the Jeungpyun with brown rice.
