【产品名称】：大米蛋白
【英文名】：Rice protein
【提取部位】：大米
【主要成分】：清蛋白、球蛋白、醇溶性蛋白和谷蛋白
【含量】：80%
【外观】: 白色粉末
【溶解性】：大米蛋白溶解性较低，主要因大米蛋白含75%~90%碱溶性谷蛋白，这些谷蛋白由许多大分子片断通过二硫键形成，彼此交联而凝聚，而溶于水的清蛋白仅占大米蛋白2%~5%。Samson Agboola等发现，在pH 4~7时，大米蛋白谷蛋白溶解性增长缓慢，而接近pH 9时，蛋白溶解性迅速增加；同时，改性会对大米蛋白溶解性产生一定影响。利用酸法脱酞氨对大米蛋白进行改性，能使其溶解性增加，溶解度最高可达96.6%。另外，王章存等对热变性大米蛋白研究发现，米蛋白经高温作用后溶解性较低，甚至凝固成为不溶性成分。

大米、米糟、米糠等原料都可用来制备大米蛋白，围绕大米蛋白开发和利用，研究者提出各种不同制备方法，主要有：溶剂提取、酶法提取、碱法提取、酸法提取、物理提取和复合提取法。 大米蛋白生物活性肽 ，营养补充剂，食品添加剂,可食用膜
