摘　　要：对采用CaO从含铬革屑中提取胶原水解物的条件进行了研究。通过比较不同CaO用量、反应时间和反应温度对胶原水解物提取率、灰分含量的影响,并对胶原水解物的铬含量进行了检测,确定了CaO从含铬革屑中提取胶原水解产物的最佳条件为:CaO用量6%(按含铬革屑质量计),反应温度61℃,反应时间1h。The reaction condition of extracting collagen hydrolysate from chrome shavings in presence of CaO was investiga- ted. The influence of reaction time, dosage of CaO and temperature on collagen extraction ratio, ash content were studied. And the chrome content of collagen hydrolysate was detected. The optimum condition of extracting collagen hydrolysate from chrome shavings is obtained as follows： CaO dosage is 6% on weight of chrome shavings, reaction temperature is 61℃, and reaction time is lh.
