Structural, functional and antioxidant properties of Lentinus edodes protein hydrolysates prepared by five enzymes.

The purpose of this study was to investigate structural, functional and antioxidant properties of Lentinus edodes protein hydrolysates (LEPHs) by alcalase, protamex, trypsin, papain and neutrase. Structural and functional properties were determined using gel electrophoresis, Fourier transform infrared spectroscopy, laser scattering, fluorescence spectroscopy, emulsifying properties etc. Antioxidant activities were detected by Fe chelating, hydroxyl and DPPH radical scavenging assays.
