用菜籽饼制取氨基酸水解液的试验研究

Preparation of Hydrolytic Agent of the Amino Acid From Rape Seed Pie

用菜籽饼作原料 ,以酸水解的方法制取氨基酸水解液的试验条件确定为 :容器加热温度 110～ 12 0℃ ;反应物温度 10 4～ 10 8℃ ;盐酸浓度 9%～ 11% ;反应时间 18～ 2 0h ;盐酸容量 (mL)与菜籽粉质量 (g)的比值约3∶1,氨基酸水解液的 pH调节至 5。氨基酸水解液的氨基酸含量可达 12 %～ 13% ,水解率可高达 10 0 %。

A hydrolytic agent of amino acid is prepared from rape seed pie.in which the experimental acid-hydrolyzing condition is as follows:Container 10～120 ℃, temperature of reactants 104～108 ℃,concentration of HCl 9%～11%reating time 18～20 h,ratio of HCl volume(mL) and seed-pie weight(g)3∶1 and the pH value of amino-acid hydroligtic agent 5.100% hydrolysis can achieved when amino-acid concentration in hydrolytic solution at 12%～13%.
