摘　　要：α-半乳糖苷酶属外切糖苷酶类,普遍存在于动、植物及微生物中,在食品、饲料、医药、造纸等领域应用广泛。论述了α-半乳糖苷酶的催化机理、底物特异性方面的研究进展,并讨论了其在食品工业中的应用及发展前景。Alpha -galactosidase belongs to exoglycosidases, and widely exists in animals, plants and mi-croorganisms. It is widely used in many fields such as food, feed, pharmaceutical and papermaking. The progress in catalytic mechanism and substrate specificity of a - galactosidase is discussed. The applica- tion and development prospects in food processing are also reviewed.
