1, mountain spring effect, optimizing water quality
Mountain spring water is the most ideal water for making tea, which is rich in various trace minerals, with less chloride content and sweet water quality. At present, strong oxidizing chlorine dioxide is usually added to drinking water in cities for disinfection, and tap water will contain residues after chemical reaction (disinfection), which will cause damage to cells and tissues if ingested into human body.
When boiling water in an iron pan, chlorine dioxide reacts with iron, which is converted into nontoxic chloride ions and water, and iron is converted into ferrous ions, which are immersed in water, so that the boiled water has the effect of mountain spring water.
2, health care, iron and blood.
Ferrous ion is extremely beneficial to human body: firstly, it is a strong antioxidant, which can effectively remove free radicals (substances that destroy cells and tissues) in human body and maintain health. There are two sources of ferrous ions in iron pot boiling water:
(1) Chemical reaction between oxidized substances such as chlorine dioxide and iron.
(2) Natural dissolution of iron. Experiments show that the use of iron pot boiling water can release a large number of ferrous ions easily absorbed by human body, which can effectively supplement human needs and prevent anemia.
You'd better use these containers to make tea:
1. Ceramic cup: Because of its special materials and processing technology, ceramic cups hardly release harmful substances during use, so ceramic cups are the best choice for making tea.
2. Glass: Glass does not contain organic chemicals during the firing process. When people drink tea from a glass, they don't have to worry about chemicals being drunk into their stomachs. In addition, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the cup wall. Therefore, drinking tea with a glass is relatively healthy and safe.
3. Enamel Cup: The traditional enamel cup is made of thousands of degrees of high-temperature enamel, and it does not contain harmful substances such as lead, so it can be safely used.
Therefore, if you want to drink a cup of tea with strong fragrance, it is best to brew it with tea sets such as ceramic cups, glasses and enamel cups. The thermos cup is not completely impossible. You can soak the tea first, and then pour the tea soup into the thermos cup. On the one hand, it can keep warm for a long time, on the other hand, it can make up for the loss of nutrition.
In fact, it is not advisable to make tea in a thermos cup. Please pay attention to the correct container for making tea.
