Abstract:The experiment made wild blueberry as the raw material to make into sweet blueberry wine and studied gelatin，bentonite，PVPP，chitosan four clarification agent on the effects of the sweet blueberry wine clarification.Then single factor experiment and orthogonal test was made on compound clarifying agent. The results showed that the compound clarifying agent and cold treatment could achieve effect of clarification. The best addition amount of bentonite and chitosan were 0.45 g/L and 0.25 g/L，clarified for three days under - 5 ℃，its luminousness could reach 98.40 %，the alcohol content was 17.0 % （vol） ，total sugar content more than 55 g/L and total acids content 6.8 g/L，The sweet blueberry wine showed bright ruby red colour，harmonious aroma and mellow taste.
