The degradtion of condensed tannin to tannin oligomers or monomers with low molecular weight is of great significance for improving their bioavailability and realizing high value-added utilization. This article comprehensively summarizes the research progress of condensed tannins in the fields of microbial degradation (fungal, bacterial), chemical degradation (acid degradation, alkaline degradation, precious metal catalytic degradation and biological enzymolysis), resin catalytic degradation, etc. The problems and solutions are summarized, and the future development direction is prospected.

Key words: condensed tannin, degradation method, reduction, chemical activity
