It can be said that making tea in a vacuum insulated cup is a common way of brewing tea, because tea in a vacuum insulated cup can be brewed directly with boiling water regardless of the season.
Therefore, many people are concerned about whether the vacuum thermos can make tea, and whether it will harm the body after drinking tea in the vacuum thermos. Therefore, there are two opinions among the crowd. One is that you can use a vacuum thermos to make tea, and the other is that you cannot use a vacuum thermos to make tea, and they have their own reasons. Let's take a look at whether the vacuum insulated cup can make tea?
The vacuum insulated cup can make tea mainly from the perspective of the thermos cup itself, because the vacuum insulated cup is made of austenitic 304 stainless steel, which can be used in medical appliances or edible utensils, so there is no problem in making tea.
The vacuum insulated cup cannot make tea mainly from the perspective of tea, because the tea leaves will affect the nutrients of tea after soaking for a long time when the water temperature is very high. Because tea is rich in a variety of nutrients, such as a variety of vitamins, minerals, as well as tea polyphenols, caffeine, tannins and other components with pharmacological effects.
However, these nutrients are afraid of continuous high temperature. The tea leaves are soaked in high temperature water for a long time, and the color of the tea water is thick and the bitterness is aggravated. Aromatic substances will accelerate volatilization, the tea soup will lose its proper aroma, and the vacuum insulated cup will easily generate tea scale and be difficult to clean.
We have concluded from the network and the experience of manufacturers that it is possible to make tea in a vacuum insulated cup, but the following points must be done:
1. Choose austenitic 304 stainless steel vacuum flask;
2. The tea should not be soaked for too long, that is, the tea should be drunk in time after it is soaked, preferably within two hours;
3. After drinking the tea, clean the vacuum insulated cup in time to reduce the chance of tea scale production in the inner bladder of the vacuum insulated cup.
As long as these points are done, there is absolutely no problem in making tea with a vacuum thermos. One of the important points is to choose an austenitic 304 stainless steel vacuum flask.
