Formaldehyde used to soak chicken feet does indeed pose certain risks to the human body, but that does not mean formaldehyde has no benefits. Let's now introduce the functions of formaldehyde.
Industrial dye
Formaldehyde has multiple properties and can be used for making adhesives, dyes, coatings, and more. Therefore, it is widely used in industry. For example, it is mainly used as a dyeing assistant and a resin finishing agent to improve wrinkle resistance and shrinkage prevention in textile products.
Sanitization
Due to its strong disinfectant properties, formaldehyde can also be widely used in livestock farming. For example, formaldehyde can be combined with potassium permanganate to fumigate livestock shelters or disinfect chicken eggs before incubation.
Preservation of corpses
In medicine, formaldehyde is usually defined as a water solution of formaldehyde with a concentration of 35% or above. It is a coagulant for proteins. Its effectiveness depends on the temperature and environment during use. When the water temperature is typically controlled at 23°C to 26°C, formaldehyde under such conditions has a preservative function and can be used to soak corpses.
Prevention and treatment of fish diseases
Formaldehyde can be used in aquaculture for the prevention and treatment of fish diseases and water quality improvement. It has significant therapeutic effects on bacterial, viral fish diseases, and parasites such as Ichthyophthirius multifiliis, Trichodina, and Gyrodactylus.
In the prevention and treatment of fish diseases, formaldehyde is mainly used to prevent and treat fish diseases caused by crustaceans and harmful swordtail copepods and water centipedes that affect fish fry and eggs.
