Abstract: The effects of heat treatment on the molecular weight of the hydrolysis of soybean protein isolated at differenttemoratures for different time periods were studied with alcalase 2.709 as an example .The results showed that the degree ofhydrolysis of soybean protein could reach 20% after it was heated at 90℃ for 15min.On the condition oligo—peptide withmolecular weight between 200 D and 600 D could be prepared.

Key words: heat treatment, soybean protein, enzymatic hydrolysis, degree of hydrolysis
