摘要
以粉末状活性炭为脱色剂,明胶复合酶解液在不同条件下进行了脱色研究。通过单因素试验和正交试验,确定最佳工艺条件为:活性炭用量为1.5%(w/w),pH为5.5,温度35℃,脱色时间为40min,胶原蛋白酶解液脱色效果明显,脱色率为86.21%,肽损失率为6.12%。
With the active carbon as deeoloriser, the glutin hydrolysate is deeolored in sorts of conditions： the quantity of active carbon used, pH, temperature and time. Through single factor and oahogonal experiment, the best condition is that：the quantity of active carbon used is 1.5% ,pH = 5.5,T = 35℃ ,t = 40 min. The deeoloared effget on the glutin hydrolysate is clear, the rate of deeolouring is 86.21% and the peptides lose rate is only 6.12%.
