植酸酶-木瓜蛋白酶协同改性对大豆分离蛋白冻融稳定性的影响
Effect of Phytase and Papain Hydrolysis on Freeze-thaw Stabilization of Soy Protein Isolate
摘要
Abstract
In order to prepare soy protein which is applied to the freeze-thaw environment,in this study soy protein isolate as raw material,the phytase-papain collaborative limited hydrolyze soy protein isolate (DH≤4%),the O/W emulsion was made of hydrolyzates by high pressure homogeneous,study different hydrolyzates emulsion after freezing-thawing treatment on the sample surface area of the average particle size,oiling yield,creaming index,flocculation degree and coalescence degree.The results showed that soy protein isolate by phytase-papain modified,the freeze-thaw stability of the emulsion was significantly (P<0.05) higher than the unmodified protein,freeze-thaw stability of the DH 4% emulsion improve the most significant.关键词
