摘　　要：构树在我国各地均有分布,具有易成活、繁殖快、适应环境能力强等特点。构树叶营养丰富,是潜在的优质蛋白质来源,经过提取提纯后能广泛用于食品加工行业,具有重大的经济价值。以构树叶粉为原料,研究了不同提取方法和参数下的粗叶蛋白含量和提取率,以粗蛋白提取率为指标,确定提取的最佳方式为酸热法提取叶蛋白,提取条件为pH值3、加热温度60℃、液料比30∶1。Broussonetia papyrifera which belonged to Moraceae. Broussonetia was full of protein and many kinds of nutrions, which mainly consisted in its leaf. The deep processing of leaf proteins had great application prospect and economic benefits. This paper, the different extraction methods and parameters of the leaves powder on the extraction yield and contents were discussed. With crude protein extraction for index, determined the optimal extracting technical parameter as follow ： pH value 3, the heating temperature 60℃, ratio of liquid to raw material 30 ： 1.
