Collagen peptides with controllable molecular weight range were prepared by using enzymatic hydrolysis coupled with membrane separation. The effects of enzyme type, molecular weight and volume of filtration on the enzymolysis?membrane separation process was investigated. The results showed that the molecular weight of the permeated liquid treated with 3 kDa ultrafiltration membrane was mainly distributed in 4.0, 1.6 and 0.6 kDa, share ratio were 13.7%, 34.8% and 51.4%. The molecular weight of the permeated liquid treated with 8 kDa ultrafiltration membrane was mainly distributed in 8.3, 4.0, 1.6 and 0.6 kDa, share ratio were 14.5%, 22.7%, 37.7% and 25.1%. It was found that the protein conversion rate was increased by 15% compared with the traditional enzymatic hydrolysis process, thus, enzymatic degradation coupled membrane separation is possible strategy for preparation of uniform molecular weight collagen peptide.
