Tea bags on the market can be divided into round, square, double bag W shape and pyramid shape according to different shapes; According to different materials, the tea mesh bags can be divided into nylon, silk, non-woven fabric, pure wood pulp filter paper, and corn fiber. When it comes to the corn fiber tea bag, many people are particularly concerned about its safety. So, is corn fiber tea bag harmful and toxic to people?
What is corn fiber? This is a synthetic fiber, also called polylactic acid fiber. PLA fiber is made of corn, wheat and other starches, which are fermented into lactic acid, then polymerized and spun. From this point of view, tea bags made of corn fiber are non-toxic.
However, it is difficult to say whether different manufacturers will adulterate other chemical ingredients in the raw materials during the production process, which will lead to the release of toxic and harmful substances from the PLA corn fiber tea bag when it encounters hot water. Therefore, when buying corn fiber tea bags, we must pay attention to distinguish the true from the false.Wish company supply the PLA Corn fiber certification which can show it is pla corn fiber and even EU certification.
Generally speaking, corn fiber pyramid tea bag can be easily torn. After burning, the biodegradable corn fiber tea bag will also make people feel like burning hay, which is particularly flammable and has a plant smell. If the tea bag is difficult to tear, and the color is black when it is burned, and the smell is unpleasant, then its material is probably not pure corn fiber.
For tea lovers who like to drink tea bags, they must choose the best tea bags. However, no matter what kind of tea bag is made of, whether it is nylon, non-woven fabric or corn fiber, the key factors to test its quality lie in five aspects: strong toughness, whether it can withstand high temperature, whether it can be quickly wetted after brewing, whether the tea powder does not leak out, and whether it has peculiar smell.
In addition, when brewing tea bags, it should be noted that the brewing time should not be too long, which should be controlled within 3~5 minutes, and the tea bags should be taken out in time before drinking. At this time, the effective substances in the tea can release about 80~90%, so it is meaningless to soak for a long time, and the taste will deteriorate.
