月见草籽粕分离蛋白的制备

Study on preparation of protein isolation from primrose meal

以月见草冷榨浸出粕为材料,初步探索碱提酸沉法制备月见草籽粕分离蛋白的工艺条件及其功能特性。通过正交实验得到提取的最佳工艺条件为:pH12,温度45℃,提取3次,料液比分别1:12、1:10、1:8;调pH6.0、3.8二次沉淀,喷雾干燥后产品的粗蛋白含量达75.5%。

Based on primrose meal,the process conditions and functional properties of protein isolated was prepared on alkali-extraction and acid-isolation.Through orthogonal tests,the best conditions of extraction were：the pH 12,the temperature 45℃,the times of extraction 3,the proportion of the material to liquid 1：12,1：10,1：8 respectively and protein deposited at pH6.0,pH3.8.In the product gained through spray drying process the content were 75.5%.
