废弃蛋白制备复合氨基酸液的工艺研究

Technology Study on Preparing Complex Amino Acids from Plant Spent Protein Resources

本文研究报道了以废弃植物蛋白资源-棉籽粕和菜籽粕为原料,采用酸水解法来制备复合氨基酸生产工艺,其工艺参数:HCl浓度4mol/L,固液比1:4(g/g),加压126℃反应9h。结果显示,利用该工艺棉籽粕与菜籽粕的水解度达到11.34%和13.96%,且可有效地降低或去除其中的毒性成分。

This paper reported the producessing technology on preparing complex amino acids from plant spent protein resources - cottonseed cake and rapeseed cake hydrolyzed by HCl, and the optimum parameters were： the HCl concentration 4mol/L, the ratio of cake to water is 1：4（g/g）, reacting 9h under 126℃ with added pressure. The results showed that the hydrolysis degree of cottonseed cake and rapeseed cake are up to 11.34% and 13.96% respectively, and the toxic components of cottonseed cake and rapeseed cake cou1ld be reduced or wiped off.
