摘要:

采用Ca2+、Fe2+、Mg2+、K+、Al3+、Zn2+等6种不同金属离子含量的水冲泡冷溶性速溶绿茶,研究水中金属离子对速溶绿茶感官品质的影响。结果表明,不同离子水质对冷溶性速溶绿茶的溶解性及其感官品质差异显著,其中Ca2+、Fe2+、Al3+、Zn2+等金属离子影响较大。研究还初步提出了冷溶性速溶绿茶冲泡用水质指标。

关键词: 冷溶性速溶绿茶, 金属离子, 水质

Abstract:

Effects of metal ions on the sensory quality of instant green tea was investigated by dissolving instant green tea in water with certain concentration of 6 different metal ions, including Ca2+, Fe2+, Mg2+, K+, Al3+ and Zn2+. The results showed that the sensory quality of cold instant green tea is significantly affected by water quality and this effect is even more deep by Ca2+, Fe2+, Al3+ and Zn2+. This preliminary study proposed the quality indexes of water for dissolving cold soluble instant green tea.

Key words: cold soluble instant green tea, metal ion, water quality
