摘要
采用酸法对鮰鱼皮中胶原蛋白进行提取,对提取胶原蛋白过程中酸的种类、酸的浓度、固液比、提取时间和提取温度对胶原蛋白提取率的影响进行研究。结果表明,酸法提取鮰鱼皮中胶原蛋白的最佳工艺为:0.5mol/L的醋酸作为浸提剂,采用1:50(m:V)的固液比,在15℃下提取72h,提取率最高为62.05%。同时,测定了鮰鱼皮中胶原蛋白的氨基酸组成。
The technology of extracted collagen from the skin of amiurus nebulosus was studied in the paper.The extraction technologies were studied,including the kind of acid,concentration of acid,immersion time and temperature.The optimal processing conditions were obtained by orthogonal experiments.The result showed skin of amiurus nebulosus was immersed in 0.5mol/L acetic acid（1：50,m：V）for 72hat 15 ℃,the ratio of the collagen extraction was 62.05%.Amino acid of collagen was determinated.
