Horse meat is a low-fat and high-protein food with more essential amino acids and less fat than other meat, but the horse meat has not been popularized in Korea due to stereotypes about horse meat. In this study, a comparative analysis of horse meat and beef was conducted using electronic nose device and gas chromatography, and as a result, there was no significant difference in the scent. However, the oleic acid content of beef is significantly higher than that of horse meat(p<0.05). Therefore, the possibility of popularizing horse meat processed products in the domestic meat processing market is expected to be sufficient.

According to the statistics of the Ministry of Environment, the amount of food waste generated in Korea is 15,903 tons, which accounts for about 30% of the daily household waste. Food waste in Korea is on the rise, and various odors, greenhouse gases, and leachate generated in the process of discharging, transporting, and processing are emerging as social problems. Accordingly, there is a need for a method for recycling food waste. Therefore, this study was carried out to establish an appropriate limiting dose by manufacturing fertilizer mixed with food waste powder and treating it on tomatoes to investigate the growth and yield of crops. The experiment was carried out with continuous cultivation in 2021 (1st year) and 2022 (2nd year), and the treatment groups were set to No Treatment (NT), Chemical Fertilizer (CF), Mixed Fertilizer (MF), and Mixed Fertilizer×2 (MF×2). As a result of the 1st year growth survey, shoot and root length did not show a significant difference between the treatment groups, and the fresh weight showed a significant difference between the MF and MF×2. As a result of the 2nd year growth survey, there was no significant difference in shoot length, root length, and dry weight between the treatment groups, and the fresh weight of the CF was significantly greater than that of the MF×2. The yield of 1st year, MF×2 increased significantly compared to other treatment groups. In the case of 2nd year, CF, and MF×2 show significantly high values compared to NT. Judging from these results, continuous cultivation using food waste powder mixed fertilizer did not have a significant effect on crop growth and yield. However, it is considered that several studies including continuous cultivation experiments are needed to accurately set the appropriate application amount and limit the application amount of the mixed fertilizer for food waste.

The present study collected 18 kinds of commercially circulated liquid Sansuyu (Corni fructus) in pouch form and conducted comparative analysis on markings and physicochemical characteristics in order to utilize this information as a base material for the development of Sansuyu liquid products. The most abundant valid substance was morroniside, followed by loganin and cornin, in that order. Total concentration of valid substances in Cornus fruit products produced in the Gurye region was 168.50 mg/100 g, which was significantly higher than the overall average of 130.89 mg/100 g. There were seven (1st) and seven (2nd) kinds that contained more morroniside than the overall average, six (1st) and four (2nd) kinds with more loganin than the overall average, and eight (1st) and one (2nd) kinds with more cornin than the overall average. There were also five types in which no loganin was detected. There were significant differences in the valid substances of most products according to production period. Overall, these results show that processing method standardization research on extraction conditions is needed to produce liquid Sansuyu products of excellent quality.

The imported foods, which are imported and sold domestically, are on the rise every year, and the scale is expected to be larger, including processing the imported raw materials. However, the origin of raw materials is indicated when declaring cargo for finished products of agricultural products, but the standardization of inspection information management system for raw materials is insufficient. In addition, there is a growing concern about the presence of residual pesticides or radioactivity in raw materials or products, and customer want to know production history information when purchasing agrifoods. It manages the hazard analysis of imported agricultural products, but most of them are global issues such as microorganisms, residual pesticides, food additives, and allergy components, etc. Therefore, it is necessary to share among the logistics entities in the entire transportation process the related data. Additionally, to do this, it needs to design an architecture and standardize business model. In this paper, it defines the architecture and the work-flow that occurs between the business process for collecting, processing, and processing information for tracking the status of imported agricultural products by steps, and develops XML message with UBL and the extracted conceptual information model. It will be easy to exchange and share information among the logistics entities through the defined standard model and it will be possible to establish visibility, reliability, safety, and freshness system for transportation of agricultural products requiring real-time management.

Rice consumption in Korea is continuously decreasing; therefore, methods for reducing rice stocks are now being proposed. Increasing the consumption of rice and reduce these stocks will require that the rice processing industry be developed beyond simply using cooked rice as food. The Korean people's eating habits have also diversified recently, and the consumption of bread is increasing. Therefore, breeding a cultivar for rice flour is now necessary. Here, a line suitable for processing into rice flour was cultivated by deriving a mutant line by tissue culture of Ilpum. Mutant populations were investigated for major agricultural traits in the field, and grain characteristics and endosperm characteristics were investigated after harvest. Among the lines, line 29111 had similar agricultural characteristics to the background Ilpum, and excellent grain quality, and was selected for further analysis. The physicochemical properties that determine taste were similar or improved. However, unlike Ilpum, 29111 had a non-uniform starch structure and a characteristic powdery endosperm because large and male starch grains are evenly distributed. Therefore, 29111 was viewed as a breeding line suitable for processing and for excellent agricultural characteristics and taste. The added value can be increased by diversifying the uses of rice. The taste was improved and a method for breeding cultivars with grain characteristics for glutinous rice that would satisfy both producers and consumers was presented.

The nutritional components and antioxidative activities of jujube fruit and leaf were investigated and analyzed to provide basic data for functional food materialization and processing. The nitrogen-free extract contents of the fruit and leaf were 71.92% and 41.51%, respectively. The mineral components of the fruit and leaf were rich in Ca (72.14 and 3,252.09 mg/100 g), K (899.82 and 1,708.12 mg/100 g), and P (172.11 and 286.28 mg/100 g), respectively. The major free sugars of the fruit were glucose (13.01 %) and fructose (7.35%); and of the leaf, sucrose (3.94%) and fructose (0.75%). The ascorbic acid contents were higher in fruit (135.73 mg/100 g) than in the leaf (100.43 mg/100 g). The analysis of the component amino acid showed a relatively high ratio of glutamic acid, aspartic acid, proline, and essential amino acids of leucine, but a low methionine and cystine content. The ABTS and FRAP assays indicated that the butanol fraction of the leaf was a more potent radical scavenger and reducing agent than the other five solvent fractions. The butanol fraction of the leaf also presented inhibitory effects against lipid peroxidation in a dose-dependent manner. Therefore, this study verified that the butanol fraction of the leaf has strong antioxidative activities that are correlated with its high level of phenolics, particularly rutin and quercitrin. These phenolics of jujube leaf can be utilized as effective and safe functional food substances, i.e., natural antioxidants.

Effects of dynamic high-pressure (DHP) treatments on microbial stability, vitamin C concentration, color, sugar content, color, and pH of strawberry juice were studied and compared with those of the conventional thermal treatment. Freshly prepared strawberry juice was thermally treated at $110^{\circ}C$ for 1 min or treated by DHP at 205 MPa and 20, 50, 60, or $70^{\circ}C$. The thermal treatment and the DHP treatments, both with and without integration with heating at $70^{\circ}C$, reduced the number of indigenous aerobic microorganisms by >6 log CFU/mL. Vitamin C concentration, color, and sugar content were higher in the DHP-treated juice than in the thermally treated juice, regardless of integration with heating. Compared to the thermal treatment, DHP treatments resulted in longer color retention and higher sugar contents in strawberry juice stored at $4^{\circ}C$ for 63 days. These results have demonstrated the potential use of DHP as a novel method for pasteurizing strawberry juice.

The purpose of this study is to identify the guideline's contents for dietitians' knowledge, attitudes, and practices (KAP) for the sustainability management at school foodservice. The contents for the guideline were determined by the Delphi technique of two rounds. The Delphi panels of experts were consisted of sixteen school dietitians and fourteen professors of food and nutrition with more than 10 years of experiences by convenience sampling method. Based on the literature, knowledge, attitudes, and practices required for dieticians were classified into menu management, procurement, food production, facility and energy management, waste management, personnel management, and nutrition education. Data were analyzed using SPSS for Windows version 24 and EXCEL to calculate descriptive statistics, content validity ratio, degree of agreement, and degree of convergence. As a result of the second round, the validity scores of 'knows eco-friendly certification standards and labeling systems (4.53 point)' in the knowledge category, and 'tries to purchase local agricultural products (4.87 point)' in the attitude category were the highest. From that round in the practice category, the validity scores of 'plan menus for students' health', 'purchases eco-friendly food', and 'conserves energy in pre-processing and cooking process' were the highest with 4.73 point. Applying the criteria for securing the validity of the contents, the contents of 25 knowledge items, 20 attitude items and 30 practice items were confirmed. The findings of the study can be used to develop the guideline for dietitians required for the sustainability management.
