Standards of identity for food are mandatory requirements that are set by a governing body to determine what a food product must contain to be marketed under a certain name in allowable commerce. Mandatory standards, which differ from voluntary grades and standards applied to agricultural commodities, protect the consumer by ensuring a label accurately reflects what is inside (for example, that mayonnaise is not an imitation spread or that ice cream is not a similar but different frozen dessert). A US trade organization defines the term as follows:

A standard of identity sets out what ingredients a product must contain, which ingredients it may contain, and any requirements of manufacturing. For example, "whisky" is defined as "a potable alcoholic distillate obtained from a mash of cereal grain saccharified by diastase of malt or by other enzymes and fermented by the action of yeast". It may contain caramel and flavouring. No other ingredients are allowed. If someone were to produce a whisky containing a dye, they would not be permitted to call the product "whisky", since dye is not a permitted additive. Standards of identity are set out in the Food and Drug Regulations. They may be identified by the symbol " ''" following the product name in boldface type. As such, they are official common names for products and no other name can be substituted.

A 2014 lawsuit in the United States illustrated one usage of such regulations. When Hampton Creek implied in its advertising that mayonnaise being marketed by Unilever was not "real" mayonnaise, the latter sued Hampton for defamation and cited the definitions promulgated by the
