Abstract: The effects of ultraviolet irradiation,temperature,CuCl2 solution amount and air oxidation on peroxide values of the original kiwifruit juice and the one added with aloe extract were investigated. The experimental results showed that peroxide value of the kiwifruit juice added with aloe extract is 11.12 % lower than that of original kiwifruit juice under ultraviolet light at room temperature for 7 h. Heated at 100 ℃ for 7 h,the peroxide value of the kiwifruit juice added with aloe extract is 7.24 % lower than that of original kiwifruit juice. Oxidized by 0.1 mol/L CuCl2 solution and air for 7h,the peroxide values of the kiwifruit juice added with aloe extract are 23.01% and 7.74% lower than that of original kiwifruit juice,respectively. The hydroxyl free radical scavenging ability of the kiwifruit juice added 20 ml aloe extract is 6.19 times that of original kiwifruit juice.

Key words: aloe extract(AE), kiwifruit juice, antioxidation, peroxide value
