摘　　要：采用碱法水解脱铬革屑制备胶原水解产物 ,研究了影响胶原水解产物收获率的各种因素 ,得出的结论为 :碱法水解的最佳条件为CaO用量 4% (w/w)、反应时间lh、反应温度 60℃、水 -渣比 7,在此条件下 ,胶原水解产物的收获率为 5 5 .0 3 % ,分子量分布在 1 6.1 0kDal左右。Alkali was used to hydrolyse the dechromed shavings,and the factors that may affect the yield of collagen hydrolysate,such as the amount of CaO,temperature and time of hydrolysis reaction,were studied.The optimal hydrolysing conditions were:CaO 4 %(w/w),60℃,1h,ratio of water to dechromed shavings 7∶1.Under such conditions,the highest yield of collagen hydrolysate was up to 55.03%,molecular weight distribution of which was about 16.10 kDal.The physical and chemical properties of the collagen hydrolysate were also detected.
