Food processing is the transformation of raw ingredients, by physical or chemical means into food, or of food into other forms. Food processing combines raw food ingredients to produce marketable food products that can be easily prepared and served by the consumer. Food processing typically involves activities such as mincing and macerating, liquefaction, emulsification, cooking (such as boiling, broiling, frying, or grilling), pickling and preservation, canning or jarring (primary-processing such as dicing or slicing, freezing or drying when leading to secondary products are also included).
