Gelatin, Carmine, and Rennet Labeling in the U.S.

An Australian vegetarian planning an upcoming visit to the United States emailed The VRG in April 2015 about whether gelatin, rennet and carmine must be labeled on food packages. Various sources that she had consulted left her with questions so she turned to us for clarification.


A common gelling agent and thickener, gelatin is derived from the bones and skins of cows, pigs, or fish.When used as a food or beverage ingredient gelatin must appear on a food package’s label. Source (bovine, porcine or fish) does not have to be specified.

When used as an incidental additive or as a processing aid in insignificant amounts gelatin is exempt from food labeling requirements. This is the case when gelatin is used as a clarifying agent in wine, beer or juice or used as a carrier in juice or soft drinks (FDA, VRG 1, VRG 2).


A red-to-purple coloring pigment obtained from dried bodies of the female insect Coccus cacti, carmine (or cochineal) must be labeled in a packaged food or beverage product because it is a potential allergen (FDA).


An enzyme used in cheese production, rennet must be declared on a food label. It may appear simply as “enzymes.” Source (animal, plant or microbial) does not have to be stated (FDA).


The information provided above applies only to labeling of pre-packaged food and beverage products. In 2014, the FDA issued labeling requirements pertaining to restaurant foods which will go in effect on December 1, 2015. Nothing is stated about ingredient labeling of foods served at restaurants or at similar establishments (FDA).

According to this FDA document patrons may request information about restaurant food on an individual basis. Whenever there’s doubt about a specific food ingredient, we recommend that you visit the restaurant website or call and ask to speak to a manager.
