Abstract: Producing good quality lipid-soluble tea polyphenols (LTP) was the research focus at home and abroad. Tea polyphenols’ modification by solvent, emulsion and molecular modification were reviewed in this paper. The advantages and disadvantages among these three methods were compared. The antioxidant properties of liphophilic tea polyphenols and its mechanism were introduced. Its antioxidant properties in different antioxidant systems were compared. And the application of LTP as antioxidants was forecasted. At the same time, the developing direction of LTP production was proposed.

Key words: lipid-soluble tea polyphenols, modification, antioxidant
