中文摘要: 对纯碱法提取鸡皮明胶进行研究,以碱浓度、浸碱时间、提胶温度、提胶时间为单因素,以提取率为响应值。鸡皮明胶碱法制备的最佳工艺条件为:碱浓度0.07 mol/L、浸碱时间30.00 h、提胶温度65.00℃、提胶时间2.00 h。此最佳条件下所得明胶的提取率为(12.03±0.47)%。
中文关键词: 鸡皮  碱法  明胶  提取率
Abstract:To prepare of gelatin from chicken skin,effects of NaOH concentration,NaOH treatment time,extraction temperature and extraction time on extraction rate of gelatin were investigated.The optimum conditions were obtained through an response surface design:the concentration of sodium hydroxide was 0.07 mol/L,the sodium hydroxide treatment time 30.00 h,the extraction temperature 65.00℃,and the extraction time 2.00 h.Under these optimal conditions the yield of gelatin was(12.03±0.47)%.
