Formalin is actually a name of a chemical substance consisting of a mixture of formaldehyde, methanol and water. Because it is widely used as a preservative of dead bodies. But lately often misused as a food preservative. For example, if we combine this formalin into a material such as fish meat, the formalin will be absorbed by the meat of fish with ease, then formalin will remove cells from the fish meat and replace it with a more rigid formaldehyde.
The result will be preserved meat or fish did survive for a long time, besides that the fish meat will not rot, because formaldehyde was capable of killing microbes or germs which are usually small role in the process of decay. Let us imagine if the meat was preserved with formalin before we eat, sad, of course very dangerous.
Meanwhile, when used to preserve corpses, obviously very helpful, because it was fast decaying corpse, using formalin, then the body can survive long enough. preserved corpse so what? In some cases the bodies are required to be tested like anatomy lab that uses the body as lab materials.
Because the durable power was incredible then misused as a food preservative, but the government has issued laws that prohibit the use of formalin in food. But in fact there are still many foods market using formalin circulating freely.
