原始语种摘要: Abstract(#br)As a residue of oil processing, research about Paeonia ostii cake has not been reported. We used six enzymes to hydrolyze the Paeonia ostii cake and obtained six enzymatic polypeptides. The enzymatic polypeptide yields of the six methods were between 10.0 and 25.0 % and average molecular weight was between 3.0 and 10.0 kDa. The average particle size of six enzymatic polypeptides was less than 1000.0 nm. The enzymatic hydrolysis method had a significant effect on the surface morphology of the enzymatic residues. The enzymatic polypeptide from alkaline protease method had better thermal stability and stronger infrared absorption. The eight essential amino acid contents of six enzymatic polypeptides from pepsin, papain, neutral protease, protemax, trypsase and alkaline protease...
