醇洗前处理对樟树籽仁分离蛋白产品 及其蛋白质结构的影响Effects of ethanol washing pretreatment on camphor seed kernel protein isolate and its protein structure
为解决樟树籽蛋白色泽深、纯度低的问题,将樟树籽脱壳、冷榨脱脂、粉碎后制得脱脂樟树籽仁粉,经不同体积分数乙醇前处理后,用碱溶酸沉法制备樟树籽仁分离蛋白(CPI)。对CPI的白度值、纯度、溶解度、分子质量和结构进行分析。结果表明:经55%~85%乙醇前处理,CPI色泽明显改善,其中经65%乙醇前处理后制备的CPI白度值由(0.70±0.02)%提高至(6.00±0.02)%;经95%乙醇前处理,CPI纯度由(60.61±0.35)%提高至(87.45±0.14)%;经85%乙醇前处理,CPI的溶解度由(81.87±0.15)%提高至(92.12±0.16)%,而经95%乙醇前处理后其溶解度下降至(...
