问:
开水,茶叶将是广泛的损害维多利亚荤做?
答:
很多人认为泡茶不应使用沸腾的理由是高温可以破坏维生素C的茶,特别是维生素C含量的水,绿茶,更不应比富人用沸水冲泡。其实,这xx是一种误解。
茶叶研究人员已在维生素C,稳定所做的个案研究,他们发现水在100℃水溶性维生素C为10分的83%遭到破坏。然而,沸水泡茶,也没有的维生素C很大的破坏,这是因为维生素C茶更难以分解,其相对稳定的根本原因在于茶含有的茶多酚,可以和铁离子,铜离子互动,从而抑制了维生素分解角因此,高温可损害xx维生素C,但茶和白水两种不同的条件下,这两者之间的巨大差距损害的程度,人们的误解,正因为这种差异的存在不容忽视。
另一方面用开水,泡茶,泡茶,双方的更大和更有效,其中传播,但也可在水中溶解提取茶更香(如咖啡和茶盐苯酚,比其他更物质),使更多的酒精和清新的茶味道。所以,合理的,科学的方法是在酝酿用沸水{dy}泡茶,冲泡5-10分钟的时间是这个茶叶质量适当时间(平均价值和营养价值,味道)较好。

Tea will be a substantial water damage dimension C do?
Question:
boiling water, tea will be extensive damage to the Victoria C do?
Answer:
a lot of people think that brewing tea should not use boiling water on the grounds that high temperatures could damage the tea vitamin c, vitamin c content in particular, green tea is even more inappropriate than the rich brew with boiling water. In fact, this is totally a misconception.
tea researchers had done in the stability of vitamin c, case studies, they found that the water soluble vitamin c at 100 ℃ for the 10-min are 83% destroyed. However, brewing tea with boiling water, and no significant destruction of vitamin c, this is because the vitamin c tea is more difficult to decompose, and its relatively stable underlying reason is that tea contains more polyphenols, they can and iron ions, copper ions interact, thereby inhibiting the decomposition of vitamin c. Therefore, high temperature can damage the natural vitamin c, but tea and Baishui two different conditions, there is a big gap between the extent of damage, people s misunderstanding is being ignored because of the existence of such differences.
the other hand, brewing tea with boiling water, making tea, the aroma of both greater and more effective dissemination of them, but also make tea in the water extract was dissolved more (such as coffee and tea more than salt phenol and other substances), so that the more alcohol and refreshing tea taste. Therefore, a reasonable and scientific methods when brewing is the first brew tea with boiling water, brewing time 5-10 minutes is appropriate at this time of the tea quality (mean value and the taste of nutritional value) was better.
Answer:
will. Therefore, with the 80-degree water for tea will not undermine the dimension C.
