摘 要：
以罗非鱼皮胶原多肽(TSP-I)为配位体,采用水合体系法与硫酸锌螯合,制备可用于补锌剂的多肽螯合锌产品。以响应面法优化罗非鱼皮胶原多肽螯合锌工艺。结果表明:最佳螯合工艺条件为:反应温度60℃、pH5.3、TSP-I与硫酸锌摩尔比2:1、TSP-I浓度3.4g/100ml水、反应时间40min。在此条件下螯合率理论值为92.57%,验证实际螯合率为92.17%。

摘 要：
The water-bath heating method was used to prepare zinc-tilapia skin collagen polypeptide chelate used as zinc supplement,and the response surface methodology(RSM) was used to determine the optimum chelation conditions for chelation ratio.It was found that under the conditions of water-bath temperature 60 ℃,pH 5.3,molar ratio of TSP-I to zinc sulfate 2:1,concentration of TSP-I 3.4 g/100 ml and chelation time 40 min,the theoretical chelation ratio is 92.57% and the practical one is 92.17%.
