In this study, chemical information on a total of 20 individual compounds was constructed to identify isoflavones from the previous reports related with used parts(seeds, leaves, stems, pods) and products of soybean(Glycine max L.). Through constructed library and UPLC-DAD-QToF/MS analysis, a total of 19 individual isoflavones including aglycones, glucosides, acetylglucosides and malonylglucosides as major compounds was identified and quantified from 14 selected soybean seeds. Among them, genistein 7-O-(2"-O-apiosyl)glucoside and genistein 7-O-(6"-O-apiosyl)glucoside(ambocin) were identified tentatively as novel compounds in soybean seeds. Besides, among malonylglucosides, glycitein 4'-O-(6"-O-malonyl)glucoside was estimated for the first time. Total isoflavone contents were distributed from 240.21 to 445.21(mg/100 g, dry matter) and 7-O-6"-O-malonylglucosides were composed of 77.8% on total isoflavone as well as genistein derivatives were confirmed as major class. It was considered importantly that the development of isoflavone-rich varieties was necessary to strengthen their effects such as anti-inflammation, anti-cancer and menopause mitigation. The qualitative and quantitative data presented precisely in this study could be help to select and breed isoflavone-rich varieties. Furthermore, their basic isoflavone profile is expected to be applied to estimate the change of isoflavone conjugates on bioavailability after soy food supplements.

This study suggests a gateway strategy for transporting agri-food exports to expand exports after examining the patterns of Korean agri-food exports by commodities and the role of export gateways. Korean agri-food exports have increased, but processed food exports have increased significantly compared to fresh agricultural products during the last 17 years. More importantly, Busan port is the main agri-food export hub in Korea. Under these circumstances, this paper examines the determinants of processed cereal-based food (HS 19) exports through Busan port using classification and regression tree (CART) analysis. As a result, the main factors that help to predict the real value of Korean exports are the GDP of the export destination countries, their distances from Korea and their GNI per capita. The destinations of Korean agri-food exports are finally classified into eight groups, which reveals the characteristics of clusters and provides useful insights for the strategies to expand agri-food exports.

Background: This study aimed to investigate the quality characteristics of Astragalus membranaceus Bunge leaf (AMBL) fermented with lactic acid bacteria and the applicability of its biologically active compounds. Methods and Results: An assessment of physicochemical properties such as pH, total acidity, free sugars, and isoflavonoid (calycosin-7-o-β-d-glucoside, ononin, calycosin, and formononetin) was conducted. Furthermore, the levels of antioxidant compounds, including polyphenols and flavonoids, and radical scavenging activities of the extracts using 2,2-Diphenyl-1-picryl-hydrazyl-hydrate and 2,2-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) were investigated. The calycosin content in the water extract of AMBL fermented with Leuconostoc mesenteroides increased by approximately twice as much as the control. Conclusions: These results indicate that L. mesenteroides can be used to improve biological activity through fermentation, and that AMBL can be used as a functional materials and edible resource in industrial areas.

This study explored a method to enhance the drying process usability of local mangoes by producing foam-mat dried powder under varying drying temperatures (50, 60, 70℃) and foam thicknesses (3, 6, 9 mm). The drying process period ranged from 60 to 390 minutes based on the set conditions, with higher temperatures and thinner foams accelerating drying. Powder chromaticity (L^*,(L^*, a^*, and b^*) demonstrated a declining trend with increasing drying temperature and foam thickness, exhibiting notable variance in chroma values. The water absorption index varied significantly, between 3.08 to 4.24, under different drying conditions, although the water solubility index remained consistent across foam-dried samples. Powder moisture content ranged from 2.53% to 3.83%, with hygroscopicity escalating with temperature and foam thickness. Vitamin C structure was compromised during the hot air drying process, especially at temperatures above 60℃. Electronic nose analysis distinguished foam-dried powder from freeze-dried powder; however, a thicker foam yielded a scent profile closer to that of freeze-dried powder. The findings provide fundamental data on mango foam drying, which is expected to improve processing and storage tech for local mangoes.

In this paper, using trade data of 57 HS 4 digit based agricultural and food(agro-food) products among 47 countries during 2005 to 2014, the international competitiveness and trade structure have been analyzed from the context of global networks employing the methods of social network analysis. Firstly, the differences in the network structure by agricultural products have been revealed. The number of disconnected groups was significantly lager in order of vegetables, fruits and processed foods. Secondly, the differences in the community structure by agricultural and food products have been also revealed. That is to say, for some commodities, the community structure has been changed dynamically, on the other hand, there are some agricultural products that have not changed its community structure despite the increasing trends of trade volume. Thirdly, even though the international competitiveness of Korea's agricultural products was still very limited in the sense that only 26 items have been included in the top3 network of 57 agricultural products, there has been possibilities of the increasing patterns of the competitiveness.

Deoduk (Codonopsis lanceolata) has a complex chemical composition that includes polyphenols, saponins, amino acids, and other unidentified compounds. The contents of tangshenoside and lobetyolin are considered as standard of quality evaluation of Deoduk. In this study, an ultra-performance liquid chromatography (UPLC) method was developed for the quantitative determination of the two marker constituents, tangshenoside and lobetyolin. The methods for determining the standards of quality were validated by measuring their linearity, specificity, limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy using UPLC. Reversed-phase UPLC analysis was conducted quantitatively to identify individual tangshenoside and lobetyolin in Deoduk extracted with 50% (v/v) aqueous ethanol. We used 21 samples to carry out quantitative analysis of tangshenoside and lobetyolin. Based on their dry weights, the levels of tangshenoside and lobetyolin were 0.36~3.54 mg/g, 0.24~1.29 mg/g, respectively. These results will be valuable as basic data for standardization of Korean Deoduk.

In this study, the effect of osmotic drying conditions of mangoes on hot air drying was investigated. Four different osmotic agents of 60 Brix, such as S60, SM10, HF80, and SG25, were prepared. Mango slabs were osmotically dried with the agents at a ratio of 1:4 (w/w) for up to 8 hours. SG25 showed the lowest weight reduction and moisture loss during the process. As a result of hot-air drying, all samples showed a high correlation with the Page model (0.9761~0.9997), and the required drying time of all samples that were osmotically dried was reduced compared to the non-osmotically dried group. After hot-air drying, the pH value increased according to the drying temperature. The L, a, and b values and the total polyphenol content also decreased. Through this study, the possibility of osmotic drying was confirmed to increase the efficiency of hot air drying of mangoes, which is expected to contribute to the industrial use of domestic mangoes.
