This study aims to develop a deep learning model to monitor rice serving amounts in institutional foodservice, enhancing personalized nutrition management. The goal is to identify the best convolutional neural network (CNN) for detecting rice quantities on serving trays, addressing balanced dietary intake challenges. Both a vanilla CNN and 12 pre-trained CNNs were tested, using features extracted from images of varying rice quantities on white trays. Configurations included optimizers, image generation, dropout, feature extraction, and fine-tuning, with top-1 validation accuracy as the evaluation metric. The vanilla CNN achieved 60% top-1 validation accuracy, while pre-trained CNNs significantly improved performance, reaching up to 90% accuracy. MobileNetV2, suitable for mobile devices, achieved a minimum 76% accuracy. These results suggest the model can effectively monitor rice servings, with potential for improvement through ongoing data collection and training. This development represents a significant advancement in personalized nutrition management, with high validation accuracy indicating its potential utility in dietary management. Continuous improvement based on expanding datasets promises enhanced precision and reliability, contributing to better health outcomes.

The domestic swine industry is currently facing a threat due to the recent increase in pork imports. This study aims to determine what factors influence consumers' intention to consume imported pork and suggest measures to support the domestic pork industry. To achieve this, we analyzed data from the Korea Rural Economic Institute's Food Consumption Behavior Survey using a binary logistic regression model. The results revealed that a higher intention to consume imported pork is linked to a higher intention to consume imported rice, purchasing meat online, frequent purchases of HMR, and procuring U.S. beef, especially among urban residents. On the other hand, a lower intention to consume imported pork is associated with a higher awareness of animal welfare certification, frequently dining out, and older age. Based on these findings, we propose the following response measures for the domestic swine industry: implementing educational programs, marketing, and advertising specifically targeting urban residents to improve their perception of domestic agricultural products; enhancing price competitiveness through distribution optimization; and developing policies to promote the use of domestic pork as an ingredient in processed foods.

This study was conducted to investigate whether there were differences in eco-friendly food, home meal replacement (HMR) purchases, and eating-out behavior according to the level of agri-food consumer competence. The data for the study were extracted from main food consumers (n=3,321) in the 2022 Food Consumption Behavior Survey. The competence index was divided into awareness-attitude-practice items, and three groups were classified by competence level. The results showed an agri-food consumer competency score of 70.62, with the highest score for awareness (73.96), followed by practice (69.28) and attitude (66.18). The frequency of purchasing eco-friendly food was higher in the excellent group compared to other groups, and quality and price satisfaction was higher with higher competency (p<0.001). Regarding HMR, the results showed that the shortage group had the lowest HMR consumption rate, and satisfaction decreased as competence decreased (p<0.001). The main reason for eating-out was to enjoy food in all groups (59.0%), followed by a lack of cooking time in the excellent group (15.7%) and hassle with food preparation in the moderate and shortage groups (17.3%, 16.6%) (p<0.001). In short, agri-food consumption competency showed differences by contents and components, and differences in food purchases and eating-out behavior by competency level were found.

이 논문은 통계청 가계동향조사 원시자료를 이용하여 가공식품비 지출액 결정요인을 파악하고자 하였다. 가구 특성과 가구주 특성이 가공식품비 지출액에 어떤 영향을 미치는지를 토빗모형을 적용하여 분석하였다. 특히, 총 13개의 가공식품 부류별로 분석함으로써 가구 특성과 가구주 특성이 월평균 1인당 지출액에 미치는 영향을 분석하고, 가공식품 부류별로 비교·분석하였다. 연구 결과에 따르면 도시가구가 농촌가구보다 곡물가공품, 빵 및 떡류, 기타식품, 쥬스 및 기타음료류에 대해 더 많은 지출을 하는 반면, 수산가공품, 유지류, 과일 및 채소 가공품, 조미식품, 커피 및 차류에 대한 지출은 더 적은 것으로 나타났다. 1인 가구의 경우, 2인 이상 가구보다 곡물가공품, 빵 및 떡류, 당류 및 과자류, 기타식품, 커피 및 차류, 쥬스 및 기타음료류에 높은 지출액을 보였지만, 육류가공품, 유지류, 과일 및 채소가공품, 조미식품에는 낮은 지출액을 보였다. 또한 소득수준이 높을수록 대부분의 가공식품 지출액이 높아지는 것으로 나타났다. 맞벌이가구의 경우 그렇지 않은 가구와 비교해 많은 부류에서 지출액이 높았다. 남성 가구주인 경우 곡물 및 육류가공품, 기타식품, 커피 및 차, 쥬스 및 음료에 대한 지출액이 여성 가구주일 때보다 높았다. 우리는 가공식품 지출액이 인구사회학적 요인에 따라 크게 달라짐을 보였다. 또한, 가공식품 부류에 따라 그 영향의 정도뿐 아니라 방향도 크게 차이날 수 있음을 밝혔다. 이는 식품제조업계와 유통업계가 가구와 가구주 특성을 고려한 마케팅 전략을 마련해야 함을 시사한다. 더욱이, 정책 입안자들은 식품 부류를 충분히 고려하여 식품산업 정책과 식생활 정책을 설계하길 기대한다.

The current research introduces a novel relationship between consumer attitudes toward time and consumer well-being, connected to organic food consumption based on the findings from 206 American consumers. Consumer motivations to seek nutritional information appears as a mediator impacting organic food purchase intentions. Practical and theoretical implications are discussed.

The rise of social media has brought the existence of “foodie” and “food bloggers” in the culinary business. The word “foodie” refers to those who highly favor and engage with food and spend a substantial amount of time collecting culinary experiences and visiting famous restaurants, while a food blogger is an individual or a foodie who uses a communication platform to share recipes and passion for food through reviews based on his or her experience. Culinary businesses use food bloggers to help promote their products and encourage consumers to try their products, which are believed to be effective as the viewers or the followers tend to take their recommendations.

Recent consumer behavior research indicates many consumers overgeneralize the relationship between food energy (i.e., calories) and bodily energy (i.e., physical and cognitive performance). We extend this idea to sport consumers, conducting two experiments among sport fans that demonstrate the imperative role of framing. Our data indicate that rivalry games and vicarious losing both increase fans’ desire to consume high-calorie, nutrient-poor foods (that is, “unhealthy” food) when food is framed as a source of fuel. This effect derives from the overgeneralized belief that the function of food is to provide energy for the body. Conversely, vicarious winning instead results in fans displaying an increased preference for healthy and environmentally friendly foods. Thus, framing, rivalry, and the result of the focal game all play central roles in the healthiness of fans’ behavior. We unpack implications for marketing scholars and consumer managers.

The site used for a nuclear facility can be released after decommissioning if the results of dose estimation meet the regulatory requirements and the site release is approved by the regulatory body. RESRAD-ONSITE, developed by the Argonne National Laboratory, is a computer code used to estimate the dose to the residents on radiologically contaminated sites. The dose estimation for site release should consider various exposure pathways, including inhalation, ingestion, and external exposure. This study used RESRAD-ONSITE to evaluate the internal exposure dose and identify radionuclides due to the intake of food produced on radiologically contaminated sites. The upper limit of the clearance level of radionuclides expected to remain at the site was used as the source terms for the dose evaluation. In addition, the amount of food intake per capita was obtained from eight countries using nuclear power generation as of 2020. The default values of RESRAD were used for other parameters except for intake by type of food and source terms. As a result of the dose evaluation, the contaminated water and vegetables showed a great contribution to the exposure dose. The dose due to tritium in drinking water was highest in the third year. In addition, regarding the intake of vegetables, the internal exposure due to 90Sr was the highest in the first year.

This study analyzed the determinants that affect the purchase of ready-to-cook seafood products using the “Consumer Attitude Survey on Processed Foods” from 2018 to 2021. Dietary lifestyle, food awareness and preference survey questions were categorized, and factors affecting the purchase probability of ready-to-cook seafood were identified through a binomial logit model. The main research findings are as follows. First, consumers had higher preference for quality, safety, and new taste factors than health and price factors when purchasing HMR (Home Meal Replacement). Second, through binomial logit model analysis, the probability of purchasing ready-to-cook seafood products was low in the group pursuing taste and economy. On the other hand, the purchase probability was high in the group seeking convenience. Third, the purchase probability of ready-to-cook seafood products was higher in households with two or more persons than in single-person households. These results suggest that differentiated product development and marketing strategies should be needed for each consumer groups in the seafood convenience food market

The influence of the food value consumption type of MZ generation on food choice attribute and sustainable food consumption behavior was studied using structural equation modeling. A survey was conducted on April 11~17, 2022, among panels aged 20 to 39. A total of 350 valid replicates (100%) were analyzed using statistical program SPSS The validity of the measurement instrument was verified through exploratory factor analysis and confirmatory factor analysis. The data reliability was confirmed using Cronbach’s alpha coefficient. The hypothesis was verified by performing path analysis through structural equation modeling using AMOS. Regarding the influence of food choice characteristics on sustainable food consumption behavior, health has a significant positive (+) effect on the selection consumption behavior of certified food and local food. Among food value consumption categories social value consumption has a significant negative (－) influence on the consumption behavior of certified food and the choice of local food. Ethical value consumption has a significant positive (+) influence on the selection consumption behavior of certified food and local food. This study is significant because it has identified sustainable food consumption behaviors that domestic consumers can adopt daily. It can use as baseline data for preparing political and institutional measures.

The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

The purpose of this study was to provide basic data for future research and suggest product development and market segmentation strategies by identifying the perceptions and consumption behaviors of vegetarians in each segment of the vegetarian market. According to food consumption value, a total of three market segments were derived, and the markets were named based on their characteristics, including ‘environment and animal protection’, ‘multiple consideration’ and ‘low interest’. As a result of analyzing the perception of vegetarian-based food, “environment and animal protection” and “multiple consideration” presented positive perceptions of a vegetarian food product. Conversely, the group stating low interest expressed negative perceptions of the vegetarian food product. An analysis of the requirements for development for vegetarian-based foods products (eg. aquafaba), indicated that the development requirements for all products, except cultured and processed meats, were high.?Considerable demand was observed for vegetarian menus and vegetarian restaurants. As a result of the analysis on the necessity of the elements of the vegetarian restaurant menu, the subjects that stated “multiple consideration” had significantly higher awareness of issues related to vegetarian foods than others.

This study researched the food culture and bean economy of the Joseon dynasty during the 16th century and according to the primary lifestyle reference『Shaemirok (瑣尾錄)』. The research analyzed the textual contents of the『Shaemirok (瑣尾錄)』. It is clear that the people of the Joseon dynasty produced more beans than grain, at a ratio of 41 to 50, respectively. The soy bean sauce consumption was split into family consumption and non-family consumption. It was evident that there was more family consumption compared to that of non-family consumption at a ratio of 7 to 3, respectively. People of the Joseon dynasty annually recorded their way of making soy sauce from 1595 to 1600. The Joseon writers edited the record six times for making meju and four times for making soy sauce. The recorded ratio displays the ingredients of soy sauce, which were: 6 Du of Mal Jang and 2 Du of salt. Mal Jang and salt had a three to one ratio, respectively. The most mentioned food was Tofu during the mid-Joseon period with fifty six mentions. The Joseon people regarded making Tofu in a Buddhist temple as a family-bonding experience. Porridge was the second most prominent food next to Tofu, among the bean-related food. Porridge appears thirty five times. There were 3 types of porridge named: bean porridge, bean powder porridge and mung bean porridge.

The culinary business in Indonesia has become attractive since it gives 41.40% contribution to total creative economy GDP in 2016 (BEKRAF-BPS, 2016). The high contribution of the culinary industry could not separate from the fact that Indonesia has plenty of local foods variety from a different area in Indonesia. Since 2016, on the scope of ASEAN Economy Community, the role of Indonesian millennial is essential. The total of ASEAN population is 625 million. 65 percent of them who was born in 1980 is around 375 million. Indonesia has approximately 84 million millennial which means 23% of the youth in ASEAN is Indonesia citizen. The current research aims to analyzed millennial behaviors and how they consumed local foods based on the online and offline appearance of the local food. Based on the survey to 121 millennial, this study found that online and offline appearance includes social media, sensory appeal, health and weight control, price, habit, and sociability and social image, have a significant influence to local food consumption among millennial. This study may provide a new perspective on how local food entrepreneurs should manage their online and offline appearance of local food to increase the product’s consumption.
