Abstract

|
|
|
The presoaking conditions of soybeans in various solution for decreasing microbial contamination and improving germination were investigated. Soybeans were treated with presoaking solutions (sterilized water, 0.1% grape fruit extract, 0.1% vitamin B₁ derivate solution AS5 and vitagen) at 25℃, 35℃, 45℃ and 55℃ for 3~12 hr and germinate at 25℃, 95%RH for 3 days. Total bacterial count and coliform count of soybeans were 6.0×10? CFU/g and 3.0×10? CFU/g, respectively, and the most of presoaking treatments decreased the microbial contamination. The increase of presoaking time induces low germination ratio compared with unsoaked soybeans and the germination of soybeans was not detected at 55℃. The germination of soybeans was effected by presoaking solutions, temperature, and time. The optimal presoaking condition for decreasing microbial contamination and promoting initial germination was using grape fruit extract at 35℃ for 6 hr.
