以双低油菜籽脱脂粕为原料,采用硫酸高温短时酸解法制备天然复合氨基酸粉,通过正交试验确定最佳工艺参数为:酸解温度130℃,时间2h,硫酸浓度6mol/L,液固比3:1.并对氨基酸液的粗制品采用CaCO3中和、减压蒸发浓缩、冷冻干燥等方法进行精制.经本工艺生产的氨基酸产品色泽为橙红色,香气正常,无异味,鲜咸适口,产品得率为38.70%,氨基氮含量为5.13%,总氮含量为8.28%,总水解度为87.50%.

Using the defatted and desquamated rapeseed meal as material, a kind of nature mixed amino acids was prepared by hydrolyzing the material with sulfuric acid under higher temperature for short time. The result of orthogonal experiment indicated that the optimum reaction conditions were as followed： reaction temperature 130℃, reaction time 2h, concentration of sulfuricacid 6mol/L, with the rate of liquid and solid 3 ： 1. After neutralizing by CaCO3, concentrating and freezing dryness ,the yield of nature mixtured amino acids was 38.70%. The am...
