Abstract:

Pig bone collagen was hydrolyzed by papain to prepare polypeptides. The single-factor method combined with an orthogonal array design involving 9 experiments of four factors at three levels was employed for maximizing degree of hydrolysis (DH) of pig bone collagen. The optimized hydrolysis for 4 h with the enzyme dose of 600 U/g at pH 5 and 50 ℃ resulted in a DH as high as 16.87% and the molecular weights of products were mainly distributed between 1 kD and 3 kD, below 5 kD.

Key words: collagen, collagen polypeptide, papain
