摘　　要：以宁夏金沙麓鼎酒庄2019年份蛇龙珠干红葡萄酒为供试对象,设置不同剂量的蛋清粉进行下胶处理,测定下胶处理后葡萄酒样品的酒泥沉降速度、沉淀紧实度、沉淀高度、常规理化指标、色度、色调和热稳定性,并进行感官评价。结果表明:当蛋清粉下胶剂量≥0.06 g/L时,处理48 h后葡萄酒样品澄清度高、沉淀紧实;不同下胶剂量蛋清粉处理的蛇龙珠干红葡萄酒的干浸出物含量、色度值之间具有显著性差异,总酸含量较对照均有所降低;当下胶剂量为0.08 g/L时,葡萄酒样品浊度差最小,为4.41 NTU,感官品质最佳。综上可以确定,蛋清粉处理蛇龙珠干红葡萄酒以下胶剂量0.08 g/L、处理时间48 h为宜。The Cabernet Genischt wine of 2019 vintage from Jinsha Luding Winery in Ningxia was used as the test object,and different concentrations of egg white powder were used for gluing treatments,then the sedimentation rates,sedimentation compactedness,sedimentation heights,conventional physical and chemical indices,chroma,tone and thermal stability of wine samples were measured and sensory evaluation was carried out.The results showed that when the gluing doses of egg white powder were greater than or equal to 0.06 g/L,the wine samples presented high clarity and compact precipitation after 48 h treatment.The different gluing doses of egg white powder treatments showed significant differences on the dry extracts and chroma of Cabernet Gernischt dry red wine,and the total acid contents were decreased compared with the control.When the gluing dosage was 0.08 g/L,the turbidity difference of wine samples was the lowest(4.41 NTU),and the sensory quality was the best.To sum up,it could be determined that the gluing dose of 0.08 g/L and treatment time of 48 h for egg white powder treatments on Cabernet Gernischt dry red wine were suitable.
