Enzymatic hydrolysis of protein is an effective way to prepare active peptides.However,the reaction kinetics is so complicated and the hydrolysates distribution is so diverse that it is difficult to quantitatively explain many theoretical problems such as mechanism or dynamics of hydrolysis.In this presentaion two model systems,i.e.peptic digestion of bovine hemoglobin (system Ⅰ) and pancreatic digestion of bovine casein (system Ⅱ) were systematically investigated by a combination of chromatographic,mass spectrometric and spectroscopic analyses.
