Vitamin K (phylloquinone) is an essential cofactor in the synthesis of active blood-clotting factors II, VII, IX and X. Deficiency of vitamin K leads to inadequate activity of these factors, resulting in bleeding. In this study, we investigated vitamin K1 content of agricultural products that are widely and specifically grown in Korea including 9 leaves and vegetables, 16 fruits, and 11 cereals and specialty crops. Vitamin K1 analysis of the agro-samples was by a validated, modified, reversed phase-HPLC method with fluorescence detection after post-column derivatization. The vitamin K1 content ranged from 1.83 to 682.73 μg/100 g in leaves and vegetables, 0.17 to 28.22 μg/100 g in fruits, and ND to 279 μg/100 g in cereals and specialty crops. Among the 36 samples, high content of vitamin K1 were found in Gugija (Lycium chinense Miller) leaves (average 682.73 μg/100 g) and Hansan ramie leaves (average 423.12 μg/100 g); however, mushroom, amaranth and Chinese artichoke showed no detectable levels. The results of ourstudy provide reliable vitamin K1 content of Korean grown agricultural products that expand nutritional information and food composition database.

This paper analyzed what factors affect increased import from ASEAN agricultural products. This study uses multi-countries gravity model approach with a dataset of agricultural import for the period of 2004 - 2014 and several explanatory variables, and then estimate it using the random-effect panel Tobit.

The results were confirmed with liquid chromatography tandem mass spectrometry (LC-MS/MS). After homogenization, samples were hydrolyzed by direct alkali saponification. Thereafter, fat-soluble components were extracted with n-hexane containing 0.01% butylated hydroxytoluene (BHT). Vitamin D contents in cereals were found to be in the range of 1.882~4.856 μg/100 g. Juda's ear and oak mushroom contained high amounts of vitamin D, at 363.85 and 199.42 μg/100 g of edible portion, respectively.

This study was conducted to develop the domestic production of a controlled atmosphere (CA) storage system, including nitrogen generator and carbon dioxide eliminator using selective gas separation membrane and operating program. Generally, the gas composition inside general cold stores constantly changes due to the metabolic activity of the respiring vegetables and fruits and leakage of gases through doors and walls. However, the CA container developed by our research team is able to control of the level of oxygen and carbon dioxide inside the reefer, making it simple and effective in operation. The efficiency of the nitrogen generator to replace oxygen with nitrogen inside the CA container was approximately 1.33% per hour. The change in oxygen concentration inside the CA container during the operation refrigerator almost did not show any difference for 8 days. Therefore, CA storage container should be a promising approach to maintaining the high quality of agricultural products during storage.

The purpose of the study is to determine how consumers perceive certification marks for agricultural products. The study examined three agricultural product certifications, such as the certification of environment-friendly agricultural products, Good Agricultural Procuts (GAP) certification mark, and United States Department of Agriculture (USDA) certification mark. A survey was utilized for data collection from adults over the age of 19 in November, 2013. A total of 390 questionnaires were distributed, and 300 of those were obtained for an analysis of the study. The results were as follows. First, consumers' awareness of, image of, and credibility on the agricultural products with the certification marks were not significantly different among the three certification marks except consumers’ awareness. Second, consumers’ purchase intentions for and willingness to pay for the agricultural products with the certification marks were not significantly different among the three certification marks. Third, these variables were not significantly different between buying group and non-buying group except consumers’ awareness. Lastly, buying group and non-buying group were significantly different only in gender and marital status. The findings offer implications to the food and food service industry regarding consumers’ purchase of certified agricultural products. Further, the study enforces the roles of food industry for environment.

The purpose of this study was to investigate the relationships among recognition, preference, and purchasing characteristics for Changnyeong onions and garlic as well as festival satisfaction among participants at agricultural product festivals in the Changnyeong region. Results showed that festival satisfaction of ‘place of festival’ was highest while ‘convenience facility & event contents’ earned the lowest scores. Most subjects (90.5%) had purchased Changnyeong agricultural and processed products. A major purchasing type was fresh agricultural products (66.7%). The pathways to recognize Changnyeong agricultural products were mostly ‘promotion by related institutions’ (22.0%), ‘family · relatives’ (20.8%), ‘mass media’ (16.6%), and ‘festivals and events’ (16.1%). The most considered factors for purchasing regional products were ‘geographical origin’ and ‘ingredients’. Changnyeong onion showed higher scores for recognition and preference and rate of purchase experience and intention than for garlic. The correlation coefficients of recognition and preference for onion and galic were 0.603 (p<0.001) and 0.598 (p<0.001), respectively. The explanation power (R2) of related variables for purchase of Changnyeong onions was 0.258. The regression coefficients (β) for ‘recognition’, ‘preference’ and ‘convenient facility & event contents’ were positive, whereas the regression coefficient for ‘price’ was negative. Recognition, preference, and convenient facility & event contents with garlic purchase showed a positive relationship (R2=0.253). The most effective promotion method to increase sales of Changnyeong agricultural products was ‘local festivals and events’ (27.8%).
