Abstract:The main factors affecting the color change of kiwi wine during fermentation were studied by measuring chlorophyll，enzyme activity and phenolic acid content of the main color-forming substances in the fermentation system of kiwi wine，and statistical analysis of the correlation between the content of phenolic acid and color parameters.The results showed that the color change of kiwi wine during fermentation was very obvious due to the influence of various factors.The color difference value was negatively correlated with chlorophyll and polyphenol oxidase，and the correlation coefficient was-0.935 and-0.929 respectively，and reaching the significant level（p＜0.01）.Therefore，the color change of kiwi wine during fermentation was mainly affected by chlorophyll degradation and enzymatic browning.
