浸出法脱蚕蛹油脂和蚕蛹蛋白的提取

【摘要】 该文探讨了蚕蛹脱脂和蛋白质提取的方法 ,确定了浸出提取法的最佳工艺路线及方案 :溶剂为石油醚浸出的时间为 6小时 ;蚕蛹和溶剂质量比 1:1.2 ;蚕蛹的脱脂温度为 80℃。一次浸出后残油率为 10 .2 3% ,脱脂后蚕蛹再进行除臭和漂白 ,脱臭后的蚕蛹再进行蛋白质的提取 ,最终制得的蛋白粉含蛋白质为 91%。重金属含量符合国家食品标准。更多还原

【Abstract】 In this paper, the method of degreasing and extracting silkworm pupas was discussed. The optimum conditions of extraction technology and the best program were assessed as follows: the dissolvent is petroleum ether, time is six hours, the ratio of silkworm pupas and dissolvents is 1:1.2, the temperature of degreasing is 80℃, the residuum content of the first leaching-out is 10.23%. The de-odor and bleaching can be made after de-fat, then protein could be extracted from the defatted silkworm pupas, and at the end the protein powder is made. The protein content is 91%,the heavy metal content accords with national standard of food.更多还原
