Abstract：Chicken powder was used as raw material and hydrolyzed for 2,3,4,5,6,7,8,9,10 and 12 h with 6 mol/L HCl at 80,90 and 100℃.The suitable conditions for the preparation of short peptides by acid hydrolysis were selected,meanwhile,the molecular weight distribution of the hydrolysates under the conditions was also studied.The results showed that the nitrogen content of the experimental chicken was 14.36%.The optimum hydrolysis conditions were 90℃with 4 h reaction time,and the molecular weight distribution of the product was about 5.5 kDa when the hydrolysis degree was 50%.
