摘　　要：本文以降低赤霞珠葡萄酒的酸度为目的,探究赤霞珠葡萄酒以乳酸菌剂结合碳酸钾降酸工艺对葡萄酒中总酸含量以及感官品质的影响。经单因素实验和正交实验确定混合降酸最佳工艺条件:碳酸钾与乳酸菌剂总质量浓度1.5 g/L、碳酸钾与乳酸菌剂混合比例100∶1 g/g、反应时间7 d、反应温度26℃,在此条件下,赤霞珠葡萄酒的总酸含量为3.2054 g/kg,感官评分为88.7分。该研究为赤霞珠葡萄酒乳酸菌剂结合碳酸钾混合降酸提供理论依据。In order to reduce the acidity of Cabernet Sauvignon wine,the effects of lactic acid bacteria combined with potassium carbonate on the total acid content and sensory quality of Cabernet Sauvignon wine were studied.The optimal process conditions of mixed acid reduction were determined by single factor experiment and orthogonal experiment:The concentration of potassium carbonate and Lactobacillus was 1.5 g/L,the mixing ratio of potassium carbonate and Lactobacillus was 100∶1 g/g,the reaction time was 7 d and the reaction temperature was 26℃.Under these conditions,the total acid content of Cabernet Sauvignon wine was 3.2054 g/kg and the sensory score was 88.7 points.This study provides a theoretical basis for the deacidification of Cabernet Sauvignon wine by combining lactic acid bacteria with potassium carbonate.
