There are many insulated water bottle products in our life. High-quality insulated water bottle can keep the temperature of water for a long time without losing. Such performance is not suitable for tea making. Long-term high temperature environment will cause the loss of nutrients in tea.
According to the nutritionist, tea is rich in protein, fat, sugar, vitamins and minerals and other nutrients, including tea polyphenols, tannins, tea pigments and other medicinal effects, so tea is a natural health drink. Why not use higher temperature water to make tea, or insulated water bottle to make tea? In fact, the reason is very simple, because if tea is immersed in high temperature water for a long time, like warm decoction, tea polyphenols, tannins and other substances will precipitate, making the tea color strong, bitter and astringent. At the same time, high water temperature will also make the aromatic oil in tea volatilize quickly, reducing the fragrance of tea. In addition, vitamin C and other nutrients will be destroyed when the water temperature exceeds 80 C, which greatly reduces the health value.
Although the insulated water bottle has good heat preservation performance, stainless steel products are easy to be corroded by various acidic foods, so it is not suitable for soybean milk and so on. Each product has its advantages and disadvantages. We should be good at developing strengths and avoiding weaknesses, so that the harm of each product can be minimized.
