One can interpret the term "adulteration" in a variety of ways, such as removing certain valuable ingredients from a particular food product or mixing or substituting inferior components with superior ones. When a food product doesn't fulfil federal or state requirements, it's referred to as adulterated in legal terminology.
Adulteration can occur accidentally or purposely through the inclusion of a non-food item to increase the amount of food in its raw or prepared state, for preservation, or to improve its look.
Added to the list are any harmful or toxic ingredients that could make the dish unhealthy.
Examples include adding water to milk, adding animal carcasses to meat items that aren't intended for human consumption , or adding stones, gravel, sand, insects, or animal hairs to grain goods.
