Abstract

|
|
|
Soybeans were soaked in water for 3 hrs and germinated at 25℃ for 5 days followed by hot water extraction and boilding for 30 min. The prepared soymilk was analyzed for chemical composition, phytic acid and soluble minerals. Germination resulted in a slow decrease in total solids while protein recovery increased to a maximum of 92.5% after 2 days. Carbohydrate content was reduced to 65% by the 5th day of germination. The intial phytic acid content in soymilk of 1.26 g recovered from 100 g dry soybean was decreased by 41.3% while inorganic phosphorus increased more than four times from 31.3 ㎎ to 135.0 ㎎. Total soluble minerals was also steadily increased.
