Nutrition information about food is written on the label paper, which is very inconvenient for visually impaired people to recognize. In order to solve the inconvenience of visually impaired people with nutritional information recognition, this paper proposes a product nutrition information guide system for visually impaired people. In the proposed system, user's image data input through UI, and object recognition is carried out through YOLO v5. The proposed system is a system that provides voice guidance on the names and nutrition information of recognized products. This paper constructs a new dataset that augments the 319 classes of canned/late-night snack product image data using rotate matrix techniques, pepper noise, and salt noise techniques. The proposed system compared and analyzed the performance of YOLO v5n, YOLO v5m, and YOLO v5l models through hyperparameter tuning and learned the dataset built with YOLO v5n models. This paper compares and analyzes the performance of the proposed system with that of previous studies.

The objective of this study is to provide direction in the improvement of sodium labeling in an effort to reduce consumption. We surveyed confirmation and importance of food labeling and nutrition information and we also analyzed the willingness to pay on new nutrients labeling. Consumers checked the sell-by-date, product name, method of intake, but not nutritional information. They also checked for calories and carbohydrates but they were not interested in sodium, sugar, and trans fat which are health hazard nutrients. It is necessary to improve nutrition labeling, because consumers are experiencing difficulties in obtaining sodium information under the nutrition labeling system. Consumers will pay about 0.66% more if new sodium labeling is introduced. In conclusion, food labeling system can be improved by smooth and efficient access of information. for health-hazard nutritional components, such as sodium, it is important to introduce policies that reduce their intake. This can be done by providing consumers with clear and concise information. The social costs of high sodium intake could be reduced, hence improving the national health.

Bakery nutrition labeling has been implemented in the company, but most consumers have no idea about it due to lack of promotion of the product nutrition labeling information or do not have a big interest in it. As a result, various studies based on the forecast about changes in consumption patterns of the bakery market due to nutrition labeling information are needed. Especially nowadays, when buying bakery products the involvement of consumers in health and nutrition is growing. So, we need to understand that nutrition labeling information makes any causal relationship between consumer attitude and confidence, purchasing behavior in bakery products. It can be said to be a very important research. For that reason, I think this research will help to settle and activate the nutrition labeling information system for the rational purchasing decisions of consumers in the bakery market. In addition, this research could be a base material for various marketing strategies.

The purpose of this study was to standardize ingredients used by school foodservices. This study analyzed the current notation of ingredients in used by used in school foodservices through the NEIS system employed by school foodservices of elementary schools through high schools in South Korea. Specifically, this study suggests systemized standardization of ingredient classification and quality attributes of at school foodservices by applying a case study analysis. The findings from the case analysis of the Electronic Procurement System operator are as follows. Classifications for ingredients of the NEIS system used by school food services consisted of included food group, food name, detailed food name, and description. Classification was not clearly divided between the classification scheme and the attribute system. Therefore, food group, food name, and product information of each food should be categorized as the classification scheme, whereas the detailed food name (excluding product information) and description should be standardized as the attribute system, which is composed of required attributes, recommended attributes, and other attributes. This study suggests that system standardization should be carried out in the field of school foodservices, as advancements between distributors and school food service providers could affect food ingredient quality. Thus, standardization can influence purchase and distribution in many ways.

This study examined the understanding and use of information on nutrition labels based on one serving size among female consumers above the age of 20 in Seoul area. According to the survey, 69.9% of respondents were aware of the current system of nutrition labeling based on one serving size, and 51.8% of the respondents expressed their dissatisfaction with the system because the nutrition labels were difficult to understand or appeared unreliable. The nutrition label literacy of the consumers varied with respect to different packaging units. The respondents were likely to be less accurate in calculating the expected caloric intake when only portions of a multi-serving package were used. Initially 69.0% of respondents reported that they had read the nutrition label before purchasing a product but 91.9% of respondents said that they would check the label after learning how to read the label properly. It is very important to make consumers aware that the labels are very reliable sources of nutrition information. A public education campaign on the use of nutrition labels should focus on developing the consumers' ability and skills in using the label information when choosing foods.

In the present study, we conducted in-depth interviews with school dieticians and nutrition teachers to determine the local foods they were aware of and their experiences with local foods. We also aimed to obtain more detailed measures for local food vitalization and suggestions for improvements. In-depth interviews were performed with 8 school dieticians and nutrition teachers, who stated that local food vitalization was needed for school food services, because it could be a foundation for securing safefood products, student healthi mprovements, environmental protection, and the establishment of a general consumption market. However, they were aware of a higher number of disadvantages than advantages in school situations and indicated the deterioration of the quality of food products as the biggest disadvantage. The most-suggested measurement items for local food vitalization in schools included improvement of the food distribution system, expansion of education, information sharing, prevention of monopolies, improvement of food-product quality, and mass production. In addition, it was suggested that school dieticians and nutrition teachers should invest efforts in the development of excellent recipes and varied diets utilizing local foods. Therefore, system supplementation is urgently required in order for school food service officials, and consumers, to efficiently introduce and vitalize local foods. It is also necessary to foster an environment that encourages trust-based relationships with producers to maximize the effect of system supplementation. This would be the foundation for improving the health of students, improving food-service quality, nutrition management, and vitalization of the regional economy in the future, and will positively affect students' food consumption patterns even after they become adults.

The purpose of this study is to investigate current nutrition labeling status, levels of recognition and patterns of consumption of domestically processed meat products. The survey results show that 47.4% of products (81 out of 171) were labeled with nutrition information. Where general product labeling and nutrition labeling were provided, it was read by 84.9% and 66.8% of the survey subjects, respectively. The most common reasons for not reading product labeling were 'hard to understand it' (46.2%) and 'not concerned' (30.8%). This was attributed to respondents finding it 'useless' (39.3%) and 'hard to understand the nutrition contents' (32.8%). As for the positive effect of enforcing a nutrition labeling system, 62% of respondents affirmed 'ease of selecting products which are good for health'. The reading of general product labeling showed a significant positive correlation (p<0.01) with the reading of nutrition labeling. The amount the nutrition labeling was read showed a negative correlation (p<0.05) with comprehension of the information on the nutrition labeling contained. Therefore, providing more information on the nutrition labeling for the consumers of processed meat products and also educating them more comprehensively about the nutrition, which would ultimately help them improve their dietary life, is needed.

BACKGROUND/OBJECTIVES: The objective of this study was to investigate food allergens and prevalence rates of food allergies, followed by comparison of consumer attitudes and preferences regarding food allergy labeling by diagnosis of food allergies. SUBJECTS/METHODS: A total of 543 individuals living in Seoul and Gyeonggi area participated in the survey from October 15 to 22 in 2013. RESULTS: The results show that the prevalence of doctor-diagnosed food allergies was 17.5%, whereas 6.4% of respondents self-reported food allergies. The most common allergens of doctor-diagnosed and self-reported food allergy respondents were peaches (30.3%) and eggs (33.3%), respectively, followed by peanuts, cow's milk, and crab. Regarding consumer attitudes toward food labeling, checking food allergens as an item was only significantly different between allergic and non-allergic respondents among all five items (P < 0.001). All respondents reported that all six items (bold font, font color, box frame, warning statement, front label, and addition of potential allergens) were necessary for an improved food allergen labeling system. PLSR analysis determined that the doctor-diagnosed group and checking of food allergens were positively correlated, whereas the non-allergy group was more concerned with checking product brands. CONCLUSIONS: An effective food labeling system is very important for health protection of allergic consumers. Additionally, government agencies must develop policies regarding prevalence of food allergies in Korea. Based on this information, the food industry and government agencies should provide clear and accurate food labeling practices for consumers.
