从羽毛中提取复合氨基酸

The optimum condition of extracting the complex aminoacid from feather

用H2SO4水解羽毛提取复合氨基酸,研究了H2SO4的浓度、用量、反应温度、反应时间等因素对羽毛水解反应的影响,确定了H2SO4水解羽毛提取氨基酸的最佳工艺条件:H2SO4浓度为35%,羽毛∶H2SO4为1∶1.8(w/w),反应温度110℃,反应时间为8h,羽毛水解氨基酸的产率可达85%以上。

The process of hydrolyzing and extracting with sulfuric acid the complex amino acids are extracted from feather. Factors such as the effects of concentration of H2SO4, the quantity of H2SO4, the reaction temperature and time are all studied. The optimum technological conditions for hydrolyzing and extracting the complex amino acid are specified. The concentration of H2SO4 was 35%, feather∶sulfuric acid for 1∶1.8(mass ratio), the reaction temperature 110 ℃,the reaction time 8 h. Given these conditions, the complex amino acid yield 85%.
