摘要
以生产玉米淀粉的副产品玉米蛋白粉为原料,分别利用直接提取法和蛋白酶水解提取法从玉米蛋白粉中提取玉米黄色素,采用均匀设计实验的方法对提取进行优化。最佳水解条件为:中性蛋白酶在底物质量分数5%、酶质量分数1.4%、pH值7.0、温度40℃条件下水解6 h。
The corn pigment is made from corn gluten meal which is product in a corn starch plant .This paper studies a technological route of how to prepare corn pigment from corn gluten meal by enzyme extraction .The optimun experimental condition is obtained by uniform design .The best hydrolisis condition is： Neutral proteinase under substrate quality score 5%, enzyme quality score 1.4%, pH value 7.0, temperature 40 ℃ conditions hydrolisis 6 h.
