Preparation of Yak Bone Peptide and Antioxidant Activity by Enzymatic Method
In order to study the extraction rate and antioxidant activity of yak bone peptide,the effects of dif-ferent proteases on the extraction rate and antioxidant activity of yak bone peptide in vitro were analyzed.The re-sults showed that different proteases had certain effects on the extraction rate and antioxidant activity of yak bones.The extraction rate of alkaline protease yak bone peptide was 14.67 mg/mL,and the DPPH free radical scavenging rate was(73.19±2.18)％,The clearance rate of·OH was(64.35±3.25)％,and the reducing power was 0.192±0.045,which were significantly higher than those of other proteases(P＜0.05).Therefore,the prepara-tion of yak bone peptide by alkaline protease has the advantages of high extraction rate and good antioxidant activi-ty,which provides a data reference for the development of functional products of yak bone peptide.
