| 摘 要： | 对不同水质调配的绿茶饮料储藏期间汤色、主要生化成分及感官品质的变化进行了研究。结果表明:储藏过程中绿茶饮料汤色亮度下降、汤色加深,儿茶素总量下降,茶多酚、咖啡碱的含量稳定。不同水质对绿茶饮料耐储藏特性的影响差异明显,蒸馏水、纯净水对绿茶饮料汤色、儿茶素、感官品质的影响较软化水、矿泉水与自来水的小。蒸馏水调配的绿茶饮料汤色偏浅,滋味苦涩欠鲜爽,纯净水与软化水比较适合用于茶饮料的生产加工。

| Abstract: | The change of the liquor color,main biochemical composition and sensory quality of green tea beverages during storage was studied.Results showed that tea liquor color brightness decreased,liquor color deepened,the total catechins decreased during the storage.The change of the liquor color,the total catechins and sensory quality of green tea beverages made by distilled water and pure water was far less than that made by soft water,mineral water and tap water.Green tea beverages made by distilled water had a lighter color,but astringent and less refreshing.Purified water and soft water were suitable for tea production and processing. |
