摘要
以稻谷加工业副产物碎米为原料,采用超声波技术提取其可溶性蛋白质,研究了不同超声处理时间、超声功率、固液比对碎米蛋白质提取率的影响。结果表明:超声提取碎米蛋白的最优条件是超声处理时间32 min、超声功率495W、固液比1∶15;在该条件下,碎米蛋白的提取率可达90.47%。
In this paper, the effect of uhrasonication treating time, ultrasonication power and ratio of solid to liquid on the pro- tein extraction rate from cereal industry by - product broken rice was investigated. Results showed that the optimal extraction process parameters with ultrasound treatment were as follows： 32 min uhrasonication treating, 495 W ultrasonication power and solid/liquid ratio of 1：15. Under this optimal conditions, the broken rice protein extraction rate was 90.47%.
