Are corn fiber tea bags harmful and toxic to humans, and are corn fiber tea filter bags safe?
01.Tea bags on the market can be divided into round, square, double-capsule W-shaped and pyramid-shaped according to different shapes; according to different materials, they can be divided into nylon, silk, non-woven fabric, pure wood pulp filter paper, and corn fiber. When it comes to corn fiber tea bags, many people are particularly concerned about its safety. So, are corn fiber tea bags harmful and toxic to humans?
What is corn fiber? It is a synthetic fiber, also known as polylactic acid fiber. PLA fiber is made of corn, wheat and other starches as raw materials, which are converted into lactic acid by fermentation, and then polymerized and spun. From this point of view alone, tea bags made of corn fiber have no toxic ingredients.
02.However, in the production process of different manufacturers, it is difficult to say whether other chemical ingredients will be mixed in the raw materials, which will cause the corn fiber tea bags to release toxic and harmful substances when exposed to hot water. Therefore, when purchasing corn fiber tea bags, we must pay attention to distinguish the true from the false.
Generally speaking, corn fiber tea bags are easily torn. After being burned, corn fiber tea bags also feel like they are burning hay, which is particularly flammable and has a botanical aroma. If the tea bag is difficult to tear, the color is black when burned, and the taste is unpleasant, then the material is probably not pure corn fiber.
For tea lovers who like to drink tea bags, they must choose the best ones for the choice of tea bags. But no matter what kind of tea bag, nylon, non-woven fabric or corn fiber, the key factors to test its quality lie in five aspects: whether it is strong or not, whether it is resistant to high temperature and can be quickly brewed after brewing. Moist, no extravasation of tea powder, and no peculiar smell.
In addition, when brewing tea bags, pay attention that the brewing time should not be too long, it needs to be controlled within 3 to 5 minutes, and the tea bags should be taken out in time before drinking. During this time, about 80~90% of the effective substances in the tea can be precipitated, so it is meaningless to soak for a long time, and the taste will be bad.
03.In short, corn fiber itself is safe. As for whether corn fiber tea bags are safe or not, whether they are harmful to the human body or not depends on whether they are officially produced. In this regard, it can be easily distinguished by hand tearing and burning. But no matter what kind of tea bag it is, be careful not to soak it for too long when drinking it.
