摘　　要：本文对从云南植物研究所获得的木瓜蛋白酶性质研究表明：该酶作用的最适温度为４０℃，最适ｐＨ值为５。应用试验发现：与１６６，１３９８蛋白酶相比，木瓜蛋白酶的脱毛能力较差；和胰酶相比，其软化效果良好，使裸皮粒面增白变细效果明显。因此，木瓜蛋白酶作为制革软化剂使用具有良好的应用前景。The properties of papain (Supplied by the Plant Resersch Institute of Yunnan) was studied in this paper.It shows that the optimum temperature and pH value of papain are 40℃,5.0 respectively.It was found that the unhairing ability of papain is poorer than that of protease 166,1398;and it's bating ability,however,is stronger than that of trypsin.The application of papain in leather-making is of great value.
