中文摘要: 该研究以辣木、蓝莓、番茄3种果蔬为原料生产复合果蔬饮料(Moringa oleifera blueberry tomato,MBT),通过单因素试验和正交试验优化配方,以超氧阴离子自由基清除试验及DPPH 自由基清除试验考察其体外抗氧化活性。结果表明,MBT 的最佳配方为:辣木叶汁添加量为50 %,蓝莓汁添加量为10 %,番茄汁添加量25 %,白砂糖添加量10 %,柠檬酸0.15 %;最佳稳定剂为羧甲基纤维素钠(carboxymethylcellulose sodium-Na,CMC-Na)与黄原胶的质量比值3∶1;DPPH 自由基清除率最高的是番茄汁93.59%,超氧阴离子自由基清除率最高为蓝莓汁84.53%。
Abstract:A compound fruit vegetable drink(MBT)was produced from three kinds of fruit and vegetable of Moringa oleifera,blueberry and tomato.The formula was optimized by single factor experiment and orthogonal experiment,and its antioxidant activity in vitro was investigated by superoxide anion free radical scavenging test and DPPH free radical scavenging test .The results showed that the optimal formula of MBT was:50 % of Moringa oleifera leaf juice,10%of blueberry juice,25%of tomato juice,10%of sugar and 0.15%of citric acid.The best stabilizer was the mass ratio of carboxy methylcellulose sodium-Na(CMC-Na)to xanthan gum 3∶1.The highest DPPH·clearance rate was 93.59 % of tomato juice,and the highest antioxidant anion free radical clearance rate was 84.53%of blueberry juice.
