Soybean is very important for vegetarians and vegans because of its high protein content and
abundance of vitamins, minerals, and fiber. Soybean-based foods contain an array of biologically
active compounds that can confer important health benefits such as antioxidant effects. Bioactive
peptides have been defined as specific protein fragments that have a positive impact on body
functions and conditions and may ultimately influence health. Main purpose of this research is to
optimize favourable conditions such as water, enzyme/substrate, pH, temperature, hydrolizing time
to hydrolize bioactive peptides from soybean by enzyme so that the highest protein recovery can be
achieved. From that we can choose the optimal extraction procedure. Finally, we manufacture the
hydrolized soybean powder, degree of hydrolization, molecular size of hydrolized bioactive peptides
with biochemical and microbial characteristics to ensure the best nutrion and safety for human
consumption.
