不同辐照处理对普洱茶主要化学成分及感官品质的影响
Effects of Different Radiation Treatments on The Content of Chemical Components and Quality of Puer-Tea
【摘要】 设置不同含水量、不同辐照剂量的试验发现,除咖啡碱、儿茶素特别是脂型儿茶素含量有所下降外,普洱茶中其他品质成分如氨基酸、可溶性糖、茶多酚总量以及茶多酚的氧化产物,辐照后一般都有所增加;各含水量、辐照剂量以及二者的交互作用间都存在极显著差异,但水浸出物除不同剂量间存在极显著差异外,含水量及二者交互作用不显著;经过感官审评,辐照茶样的感官品质无不良变化。
【Abstract】 Through experiment with treatments of various dosages of radiation and different initial water contents in Puer-tea, it was found that contents of amino acid, tea polyphenols and the oxidation products of polyphenols were increased; oppositely, caffeine and catechins, particularly the compound catechins were decreased; In addition, the radiation treatments had no negative effect on the organoleptic quality of Puer-tea.
