中文摘要: 以长白山榛仁分离蛋白为原料,用碱性蛋白酶Alcalase水解制备榛仁蛋白水解物,通过对水解过程中的加酶量、pH、温度和底物浓度等因素进行单因素和响应面试验,优化得出榛仁蛋白水解物的最佳水解工艺为:加酶量10 000 U/g,pH8.5,温度53.5℃,底物浓度2.0%,水解时间150 min,在此条件下制备的榛仁蛋白水解物的水解度达39.72%。
中文关键词: 长白山榛仁  蛋白水解物  响应面
Abstract:This paper took Changbai Mountain hazelnut protein isolated as raw material,prepared the hazelnut protein hydrolysates using the Alcalase,through the single factor and response surface experiment of the Alcalase volume,pH,temperature and substrate concentration,the optimal hydrolysis conditions were determined as:Alcalase volume 10 000 U/g,pH 8.5,temperature 53.5℃,substrate concentration 2.0%,hydrolysis time 150 min,the degree of hydrolysis of hazelnut protein hydrolysates reached 39.72%.
