Soybean seed, sprouts and tofu were evaluated for differences in BBI quantity. There are differences in BBI present in mature seed of different varieties of soybean as well as in sprouted soybean.

Understanding dosage amount and frequency will be important in order to select for optimum concentrations of BBI future varieties.
