The purpose of this study is to investigate changes of isoflavone and nutrients during germination of soybean varieties and to determine the optimal germination condition for soybean processing. After 5 days' germination, water content of the soybeans increased in the order of Poongsannamoolkong> Sinpaldal#2> Black#1> Jinpumkong. Ash content was higher in the order of Poongsannamoolkong> Sinpaldal#2> Jinpumkong> black#1 soybean. All varieties of the soybean samples increased in ash content during germination. Crude fat content was higher in the order of Poongsannamoolkong> Black#1> Jinpumkong> Shinpaldalkong. Crude protein content was higher in the order of Shinpaldalkong> Black#1> Jinpumkong> Poongsannamoolkong. Polypeptide subunits separated from the SDS-PAGE of the entire proteins were showing comparatively high level in the range of 2-16KD in Jinpumkong and 2-21KD in Poongsannamoolkong till the first day of germination, 2-25KD in Sinpaldal#2 till the second day, and 6-27KD in Black#l till the third day. Changes of total isoflavone contents during germination showed different patterns in soybean varieties: Jinpumkong and Black#1 had the highest total isoflavone content on the fourth day of germination, Poongsannamoolkong and Sinpaldal#2 on the first and the second day of germination, respectively.
