以低温花生粕为原料,采用醇洗法制备花生浓缩蛋白,研究了乙醇溶液体积分数、浸洗温度、浸洗次数及固液比对产品中蛋白质含量的影响.通过正交实验确定的最佳工艺条件为:乙醇溶液体积分数60%,浸洗温度50℃,固液比1∶8,浸洗次数5次(每次30 min).在该条件下制备的产品中粗蛋白含量为68.15%(N×6.25,干基),氮溶解指数(NSI)为32.72%.

The alcohol leaching process was employed to prepare peanut protein concentrate from low temperature peanut meal. The influence factors such as ethanol concentration, extraction times, extraction temperature,ratio of solid to liquid were also studied. The optimum conditions were obtained by orthogonal test as follows： ethanol concentration 60%, extraction times 5 （ once 30 min）, extraction temperature 50℃, ratio of solid to liquid 1 ： 8. Under these conditions, the content of protein in the peanut protein concentrate was 68...
