Abstract: α-galactosidase can catalyze α-galactosis bond hydrolyzing,and decompose anti-nutrients α-galactose galactosides contained in feed and leguminous food,and improve nutrients. Some α-galactosidases have a transglycosylation action at high substrates concentrations,and it's proved to be used for the oligosaccharides synthesis and cyclodextrin modification based on this feature. Moreover,α-galactosidases also have applications in the pharmaceutical,thickening agent treatment and paper industry. The author reviewed the study and application situation of α-galactosidases,and the research direction and development trends of α-galactosidases were also summarized and evaluated.

Key words: α-galactosidase; characteristic; application; research progress
