Abstract

Soy saponins are considered to be major bioactive components. In this study, ethanol extracts prepared from mature soybean and germinated seeds (0-4 days) were examined for saponin content. Results showed that concn. of saponin in extracts from mature and germinated soybeans were 2.8 and 6.1-8.9%, respectively. Saponin content increased 3.2x after germination. The concn. of soy sapogenol I, the predominant hydrolytic product of saponin, increased from 1.8 to 7.3% during the course of germination. Defatted soy flour, soy protein isolate and toasted flour were found to contain 2.3-3.5% saponin, suggesting that germinated soybean seeds are the richest source of saponins among soy products.
