不同茶饮产品的抗氧化能力分析及感官评价

Antioxidant activity and sensory evaluation of tea drinks

  • 摘要: 以总还原能力、DPPH·自由基清除率、·OH清除率、O2-·清除率作为指标,评价了不同茶饮产品的抗氧化能力,并按照《GB/T 23776-2009茶叶感官评审方法》的冲泡方法进行10种茶饮产品的感官评价,以讨论其在消费人群中的接受程度。结果表明,总还原能力由强到弱依次为绿毛峰>坨藏茶>竹叶青>昆仑雪菊>康砖>杭白菊>苦荞胚芽茶>干柠檬>苦荞全株茶>鲜柠檬;对DPPH·自由基清除率最高的为干柠檬,达到了93.58%,最低仅为30.13%(鲜柠檬);对·OH清除率最高的为干柠檬95.87%,最低的为苦荞全株茶17.64%;对O2-·清除率最高的为坨藏茶85.86%,最低的为苦荞全株茶9.08%。在感官评价中,对总分以及汤色、香气、滋味三种因子分别分析,竹叶青分值均最高。结果表明,利用不同抗氧化指标表明的抗氧化能力有所区别,总体而言,干柠檬、竹叶青2种茶饮产品表现出较高的抗氧化活性,而苦荞茶较低。此研究结果可为消费者提供对保健茶饮的消费参考。 

     

    Abstract: The antioxidant capacity of 10 kinds of tea drink products were compared with antioxidant indexes of total reducing ability,free radical scavenging activity of DPPH·,·OH,O2-·. Then their sensory evaluation with GB/T 23776-2009 methods were carried out in order to demonstrate their acceptance levels among consumers.The result showed that the total reducing ability arranged from the strongest to the weakest was:Lv maofeng Tea,Tibet tea,Zhuyeqing,Coreopsis tinctoria Nutt.,Kang Tea-brick,Chrysanthemum morifolium,Buckwheat Germ tea,dried Lemon,Buckwheat plants tea,and Fresh Lemon. Besides,the dried Lemon performed the highest free radicals scavenging activity of DPPH· 93.58%,while Fresh Lemon was the lowest at only 30.13%;the highest ·OH clearance was 95.87% of dried Lemon,whereas the lowest of Buckwheat Plant Tea's was only17.64%. On O2-· clearance,Tibet Tea showed the highest activity at 85.86%,The lowest was Buckwheat Plants Tea at 9.08%. The total score in sensory evaluation showed Zhuyeqing scores the highest in the analysis of three factors-color,aroma,and taste. In these results,the different antioxidant activity was indicated by different antioxidant indexes. Based on the trend,2 products,dried Lemon & Zhuyeqing showed higher antioxidant activity,and the buckwheat tea was lowest. All of results could be considered as a recommendation for consumers.
