How is formaldehyde produced

Formaldehyde is a substance that many people are very worried about, because this substance is very harmful to people's bodies. Rooms with excessive formaldehyde levels cannot be lived in, otherwise formaldehyde poisoning may occur, which will cause unnecessary trouble. Therefore, it is best to find a way to remove formaldehyde to prevent such a situation from happening.

Formaldehyde, which is harmful to the human body, can be said to be everywhere in our lives. The items involved include furniture, wooden floors; children's clothing, wrinkle-free shirts; instant noodles, rice noodles; blistered squid, sea cucumbers, beef tripe, shrimps; and even cars. It is not difficult to see that formaldehyde is present in all of the four most important things in our lives: clothing, food, housing and transportation. The ubiquitous formaldehyde makes people worried. Formaldehyde in Textiles

3.1 Formaldehyde is mainly used in fiber products as a dyeing auxiliary and a resin finishing agent to improve the anti-wrinkle and anti-shrinkage effects. Formaldehyde can make the color of textiles bright and colorful, maintain the durability of printing and dyeing, and make cotton fabrics wrinkle-proof, shrink-proof and flame-retardant. Therefore, formaldehyde is widely used in the textile industry. Pure cotton textiles are the most commonly used printing and dyeing auxiliaries. Most of the "pure cotton wrinkle-free" clothing or ironing shirts on the market use formaldehyde-containing auxiliaries and may release formaldehyde when worn. The formaldehyde in children's clothing mainly comes from dyes and auxiliary products that keep the colors of children's clothing bright and beautiful, as well as adhesives used in clothing printing. Therefore, brightly colored and printed clothing generally has higher formaldehyde content, while solid-colored clothing and children's clothing without prints have lower formaldehyde content. These garments containing formaldehyde will release formaldehyde during storage and wearing, especially the formaldehyde released from children's clothing and underwear, which is the most harmful.

Formaldehyde is an additive that the state explicitly prohibits from use in food and must not be detected in food, but formaldehyde has been detected in many foods to varying degrees. ⑴Existing in water-soaked food. Since formaldehyde can keep the surface color of water-soaked food bright, it can increase toughness and crispness, improve taste, and also serve as a preservative. If it is used to soak seafood, it can fix the shape of seafood and maintain the color of fish. Therefore, formaldehyde has been widely used by illegal vendors to soak various aquatic products. The water-soaked foods on the market that have been found to have formaldehyde mainly include: duck feet, beef tripe, shrimp, sea cucumber, fish maw, pomfret, octopus, cuttlefish, hairtail, squid head, tendon, jellyfish, snail meat, cuttlefish, etc. Among them, the formaldehyde content in shrimp, sea cucumber and squid is relatively high. ⑵Found in pasta, mushrooms or soy products. Formaldehyde can whiten foods and change color, so it is often used by unscrupulous vendors for fumigation or directly added to pasta, mushrooms or soy products. When unscrupulous vendors use "bleaching blocks" to fumigate relevant foods to whiten them, formaldehyde may also remain in the food. Foods in which formaldehyde has been detected include: shiitake mushrooms, flower mushrooms, rice noodles, vermicelli, bean curd sticks, etc.
