中华蚱蜢蛋白质的提取

Studies on the Protein Extracting Technology and Classifications of Acria cinerea

摘要:

对中华蚱蜢蛋白质进行了氨基酸组成分析、分类及提取工艺等方面的研究. 结果表明,中华蚱蜢蛋白质量分数56 84%,必需氨基酸质量分数 24 9%,具有很高的利用价值;各类型蛋白的提取率分别为水溶性蛋白43 4%,酸溶性蛋白 1 8%,碱溶性蛋白 1 9%,醇溶性蛋白 0 3%;提取水溶性蛋白较优的条件为固液比(g∶mL)1∶15,缓冲液 pH值 7 6,NaCl质量浓度 1 0 g/dL,提取时间4 h,提取率可为27 1%.
