The results are as follows:Defatted wheat germ was micronized useing both hammer mill and colloid mill to increase the extraction rate of protein, followed by alkali extraction and ultrafiltration, respectively. A quadratic mathematical model was statistically constructed by using of Box-Behnken central composite design and response surface methodology. Under the optimized processing parameters of 23μm particle sizes, pH 9.5 and 51℃, a maximum extraction rate, 68.6%, was achieved, which is 30.63% higher than that of non- micronized wheat germ (passing through 80 mesh sieve).

首先采用锤式粉碎与胶体粉碎相结合的方法对脱脂麦胚进行微细化处理，然后利用碱提、超滤浓缩法提取制备麦胚蛋白，并通过Box-Behnken中心组合设计及响应面分析建立预测麦胚蛋白提取率的二次多项数学模型，优化蛋白质的提取工艺，在麦胚粒度为23μm、pH值9.5、提取温度51℃的条件下，经微细化处理的蛋白提取率为68.6％，比未经微细化处理的(过80目筛)提高30.63％。2。
