Abstract: The tea polyphenols from tea is a natural antioxidant and has good anti-oxidation stability. The influences of the ultra-violet light, temperature, CuCl2 and KClO3 on acid value of the tea seed oil with tea polyphenols addition were investigated. The results showed that acid values of tea seed oil added tea polyphenols decreased 22.8% and 12.06% compared with acid values of tea polyphenols added by ultraviolet light and heating 90 ℃ for 7 hours, respectively. The acid values of tea seed oil added tea polyphenols decreased 3.63% and 7.63% tea seed oil without tea polyphenols, added by 0.08 mol/L CuCl2 and KClO3 reaction 7 hours, respectively.

Key words: tea polyphenols, tea seed oil, antioxidant, acid value
