industrial grade sodium metabisulfite eat harmful?

Industrial-grade sodium metabisulfite is very common in life. It is a food additive. We often buy food and often see preservatives or preservatives. These contain this sodium metabisulfite, but we rarely open it. Sodium metabisulfite has Many functions can be used as preservatives, bleaching agents, etc. In life, it can keep food fresh and bleach things when used as a bleaching agent, so using these correctly is harmless to our human body, but eat some.

Generally speaking, sodium pyrosulfite will decompose sulfur dioxide in the air. Residues of this compound will strongly stimulate the respiratory tract and gastric mucosa of human body, causing cough and asthma. Moreover, sodium pyrosulfite is easily soluble in water, producing sulfurous acid, which will corrode intestinal tract. In addition, because sodium pyrosulfite is artificially synthesized and its purity is less than 100, there will be some heavy metal residues, such as lead and chromium, and long-term consumption may cause heavy metals to exceed the standard.

When industrial-grade sodium metabisulfite is used as a bleaching agent, it is only used for fumigation and cannot be used for bleaching direct contact objects such as soaking. Sodium metabisulfite can cause liver and kidney damage, even acute poisoning and even death. In daily life, buyers can make simple judgments from the color and smell of food. If they buy water chestnut, they can see if its skin color is too bright, if it is bright, if there is a pungent smell, you can smell it again (if it is a fruit, you can peel off the skin to smell it). If there is a pungent smell, it may be soaked with medicine. When used as bleaching agent for bamboo shoots, preserved beancurd, biscuits, vermicelli and vermicelli, the dosage of sodium metabisulfite is calculated based on the content of residual sulfur dioxide. The limit for vermicelli and vermicelli is 0.1g per kilogram.

Generally speaking, industrial grade sodium metabisulfite will directly cause cancer, but long-term consumption will affect our body and immune function, and may induce cancer.

Well, today's editor will not explain much. I hope you have a new understanding of sodium metabisulfite. In addition, when you come into contact with such chemicals, you must be careful to avoid causing harm to yourself. Okay, let's see you next time.
