cooking(redirected from Food preparation)
Also found in: Dictionary, Thesaurus, Encyclopedia.
The preparation of comestibles by heating. In meats, overcooking can result in the production of carcinogenic polycyclic amines; undercooking carries the risk of parasitic (e.g., Taenia solium, T saginatus) or bacterial (e.g., Escherichia coli 0157:H7, Salmonella spp) infections.
cooking[L. coquere, to cook]
CAUTION!Not all toxic substances are inactivated by heat. Most microorganisms and parasites are destroyed in the ordinary process of cooking when the food is heated to internal temperatures of 160°F to 175°F. Pork must be cooked completely throughout to kill the encysted larvae of Trichinella.
Protein: Soluble proteins become coagulated. Soluble substances: These, including heat-labile vitamins, are often inactivated by boiling, and even mineral substances and starches, although insoluble to a certain extent, may be altered in this process. Starch: The starch granules swell and are changed from insoluble (raw) starch to soluble starch capable of being converted into sugar during digestion and of being assimilated in the system.
