The objective of this study was to access the effects of sensory and physical properties of Beandaeduk on 7 different combination methods (three were combined with mung bean and different proportions of water; four were combined with mung bean and various cereals with constant water), and 3 storage periods (0, 1 and 3 weeks at $-18^{\circ}C$). This experiment was consisted of sensory evaluation I (appearance, texture, taste, flavor and overall preference), II (color, moisture, volume, hardness, elasticity, viscosity and ratio materials, off-flavor and oder) and physical analysis of each sample, and questionaire survey of Beandaeduk. In sensory evaluation I except flavor, significant differences (p<0.05) were found among different combination methods of sample. Also significant differences (p<0.05) were found in sample for storage periods, except appearance. In sensory evaluation II, only moisture and oder of samples were significantly different (p<0.05) for storage periods, and there were significant differences (p<0.05) in samples among different combination methods, except elasicity. Stepwise regression for storage periods in sensory I showed that texture and taste were important factors in overall preference of sample. In the questionaire survey, preference and adding materials of Beandaeduk were different according to province. Half of respondents preferred to get instant Beandaeduk and instant mung bean powder.

The purpose of this study was to compare and analyze the importance and satisfaction of consumer selective attributes by home meal replacement (HMR) types using local ingredients. This study was conducted from December 4 to December 8, 2020. A total of 380 responses organized according to preferred types of HMR (100 for Ready to Eat (RTE), 92 for Ready to Heat (RTH), 88 for Ready to Cook (RTC), 100 for Ready to Prepared (RTP) were used for the final analysis. Statistical analysis was conducted by descriptive analysis, paired t-test, and importance-satisfaction analysis by HMR type. Findings of this study showed significant differences in consumer selective attributes by HMR type. RTE and RTC need to improve quality while RTH needs to improve quality and packaging. Notable selective attributes were quality, packaging, and information. They were located in different quadrants of each HMR type. All other attributes appeared in the same quadrant. Further research is needed to determine differences in quality, packaging, and information for each HMR type. Results of this study provide basic data for developing products and marketing strategies for each type of HMR products using local ingredients.

Poultry meat is generally exposed to quality deterioration due to lipid oxidation during storage. Oxidative stability of meat can be increased by feed supplementation. Aim of the current study was to investigate the effect of dietary supplementation of fish waste derived bioactive peptides on antioxidant potential of broiler breast meat and physico-chemical characteristics and quality parameters of nuggets prepared from breast meat. 180 broiler birds (six groups of 30 birds) were purchased. Each group was given different concentrations of bioactive peptides i.e. 0, 50, 100, 150, 200, and 250 mg/kg feed. After completion of six weeks birds were slaughtered and breast meat was stored at -18℃ for six months. Nuggets were prepared and stored at -18℃ for 45 days. Meat samples were analyzed for antioxidant activity [total phenolic contents (TPC), DPPH^· scavenging activity, and ferric reducing antioxidant power] and lipid oxidation assay at regular intervals of 1, 2, 3, 4, 5, and 6 months while nuggets were analyzed for quality (pH, color, texture and water holding capacity) parameters after regular interval of 15 days. A significant (p<0.05) effect of feed supplementation was observed on antioxidant status such as TPC, DPPH^· scavenging activity, and FRAP of broiler breast meat. Dietary interventions of bioactive peptides significantly (p<0.05) delayed lipid oxidation of breast meat than control. All the quality parameters were also significantly affected due to dietary bioactive peptides and storage duration. Thus, dietary interventions of bioactive peptides can increase the antioxidant and shelf stability of broiler breast meat and nuggets.

An ecological survey of early childhood nutrition was conducted from January 23 to February 18, to study the feeding method and weaning practice in Whaseong-gun, Kyonggi-do. This study covered a total of 283 children. Seventy three percent of the subjects had been breast-fed; 10% had been bottle-fed; others had been combination-fed before the introduction of supplementary foods. Only 26.9% of the subjects began to be fed supplementary food before the age of 6 months. The supplementary food used most frequently by the majority of children at the beginning of weaning was plain cooked rice; rarely special preparation, or different from the food eaten by the family. As for age of termination of breast feeding, 42.7% of the subjects were before 12 months; 32.8% were between 13 and 18 months of age; 24.5% were more than 19 months old. As for methods of stopping breast feeding, 44.5% of the subjects were naturally terminated while 38.5% were forced to terminate by the application of sticking plaster or medicines to the mother's nipples. The results indicate a need for nutrition and hygiene intervention to improve the weaning practice of rural area through the community nutrition education.

The purpose of this study was to compare dietary self-efficacy for sodium intake reduction and dietary behaviors by eating areas. Subjects (797 males and 767 females) were classified according to perceived dietary habit levels related to sodium intake (lowest: ${\leq}10$ (n=434), low: $11{\sim}{\leq}13$ (n=471), high: $14{\sim}{\leq}15$ (n=360), highest: $16{\leq}$ (n=299)) using an online survey with a sample that was geographically representative of the population. The highest group was significantly younger and had a higher student proportion than the lowest group. Dining contexts regarding home led to a significantly higher sodium intake in the highest group, but it was eating out for the lowest group. The highest group had a significantly lower intention to reduce sodium intake compared to the lowest group. In the home cooked meals, the highest group displayed a significantly lower cooking frequency, less effort with respect to a low sodium diet and cooking habits related to sodium intake as compared to the lowest group. Also, regarding eating out and food service, the highest group exhibited significantly lower efforts and dietary behaviors to reduce sodium intake than the lowest group. The dietary score for sodium reduction behavior in the highest group was significantly lower compared to the lowest group, for home cooked meals, eating out, as well as food service. Thus, dietary guidelines and nutrition education for the reduction of sodium intake by eating areas need to be developed and provided.

This study was conducted to explore the change in the market issues on HMR (Home Meal Replacements) using local foods after the COVID-19 outbreak. Online text data were collected from internet news, social media posts, and web documents before (from January 2016 to December 2019) and after (from January 2020 to November 2022) the COVID-19 outbreak. TF-IDF analysis showed that 'Trend', 'Market', 'Consumption', and 'Food service industry' were the major keywords before the COVID-19 outbreak, whereas 'Wanju-gun', 'Distribution', 'Development', and 'Meal-kit' were main keywords after the COVID-19 outbreak. The results of topic modeling analysis and categorization showed that after the COVID-19 outbreak, the 'Market' category included 'Non-face-to-face market' instead of 'Event,' and 'Delivery' instead of 'Distribution'. In the 'Product' category, 'Marketing' was included instead of 'Trend'. Additionally, in the 'Support' category, 'Start-up' and 'School food service' appeared as new topics after the COVID-19 outbreak. In conclusion, this study showed that meaningful change had occurred in market issues on HMR using local foods after the COVID-19 outbreak. Therefore, governments should take advantage of such market opportunity by implementing policy and programs to promote the development and marketing of HMR using local foods.

One noticeable thing about the recently opened 'Starfield Hanam' and 'Hyundai Department Store (Pangyo)' is consumer's interest and positive response to their hosted food brands ranging from restaurants, dessert cafes and coffee shops. Department store and shopping complex, so-called aggregation of lifestyle are making the most out of food brands as a differentiation strategy and consumer's interest on it act as a barometer for current consumption trend. Along with the high interest on food market, changes in lifestyle, such as increasing ratio of two or less households, advent of multiple communication channels as SNS, deluge of information and gradually developing individualism, are creating needs for convenient but high quality eating culture. This need contributed in transforming the product family which was once famous as 'Instant Food' into a 'Home Meal Replacement (HMR)'. Since local food companies are striving to keep pace with the trend and actively penetrating HMR market, regardless of long-term recession, the Korean domestic food market is steadily growing with a bright future.
