Optimization of drink formula of chrysanthemum and medlar using D-optimal mixture design and its antioxidant activity

优化了菊花枸杞饮料的配方并测定了饮料的抗氧化能力。D-最优混料设计实验结果表明:菊花枸杞饮料的最佳配方为30%菊花提取液、51%枸杞提取液和19%绵白糖溶液。在此条件下,饮料感官评定最大值达到86.20。菊花枸杞饮料浓度为100%时,可清除67.97%的DPPH自由基和51.15%的羟自由基,具有较强的抗氧化活性。本饮料颜色淡黄色,酸甜适中,口感润滑,具有浓郁的菊花和枸杞香味,是一种绿色、营养、健康的保健饮品。

Drink formula of chrysanthemum and medlar was optimized and its antioxidant activity was determined. By D-optimal mixture design,the best drink formula of chrysanthemum and medlar was..30% of chrysanthemum extract,51% of medlar extract and 19% of soft sugar solution. In this condition,the maximum value of sensory evaluation of drink was 86.20. At concentration of 100%,the drink could eliminated 67.97% DPPH radicals and 51.15% hydroxyl radicals and showed strong antioxidant activity. This drink was yellow,sweet and sour moderate,taste lubrication,with rich chrysanthemum and medlar fragrance. Thus,this drink would be a green, nutritive and healthy functional beverage.
