摘　　要：通过单因素试验和正交试验对黑枸杞梨汁复合饮料进行工艺优化,并对复合饮料稳定剂进行筛选,同时测定了复合饮料的ABTS自由基清除率及各项指标。结果表明,黑枸杞梨汁复合饮料的最佳工艺配方的各组分用量为黑枸杞5 g/L,白砂糖21 g/L,柠檬汁6 g/L,梨汁45 g/L,感官评分为87.22分。此外,0.3%的果胶添加量为稳定剂,复合饮料稳定性良好。抗氧化试验结果表明,复合饮料具有较好的ABTS自由基清除效果,清除率达70.06%。黑枸杞梨汁复合饮料的总糖含量为86.73 mg/m L,可溶性固形物含量为10.7%。此工艺条件下的黑枸杞梨汁复合饮料风味独特,具有酥梨和柠檬清香,口感酸甜适宜,呈紫红色,组织状态均匀,为黑枸杞和砀山酥梨精深开发利用提供一定的理论依据。On the basis of single factor and orthogonal experiment,the technology of Lycium ruthenicum Murr.,pear juice compound beverage was optimized,and the stabilizer was screened and the ABTS free radical scavenging rate and various indexes of the compound beverage were determined.The results showed that the optimal formula of compound beverage were as follows:Lycium ruthenicum Murr.5 g/L,white granulated sugar 21 g/L,lemon juice 6 g/L,pear juice 45 g/L,and the sensory score was 87.22.The results of stabilizer screening test showed that the stability of compound beverage was good,when pectin was used as stabilizer and 0.3%was added.The results of antioxidant test showed that the compound beverage had a good scavenging effect on ABTS free radical,and the scavenging rate was 70.06%.The total sugar content and soluble solid content of compound beverage were 86.73 mg/ml and 10.7%,respectively.Under the optimal conditions,the compound beverage has unique flavor,purple red color,uniform texture,crisp pear and lemon fragrance,and suitable taste of sour and sweet.It provides a theoretical basis for the deep development and utilization of Lycium ruthenicum Murr.and Dangshan pear.
