Categories

Food additives can be divided into several groups, although there is some overlap because some additives exert more than one effect. For example, salt is both a preservative as well as a flavor.Erich Lück and Gert-Wolfhard von Rymon Lipinski "Foods, 3. Food Additives" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2002, Wiley-VCH, Weinheim. ;Acidulants :

; subchronic (at least 90 data) and chronic toxicity and carcinogenity; reproductive and developmental toxicity. Recent work has demonstrated that certain food additives such as carboxymethylcellulose may cause encroachment of microbes from the gastrointestinal tract into the protective mucus layer that lines the intestines. Additional preclinical work suggests that emulsifiers may disrupt the gut microbiome, cause or exacerbate inflammation, and increase intestinal permeability. Other food additives in processed foods, such as xanthan gum, have also been shown to influence the ecology of human gut microbiomes and may play a role in the divergence of gut microbiomes in industrialized societies as compared to pre-industrialized societies. Although still controversial, some scientists hypothesize that these changes to human gut microbiomes may be a contributing factor to the rise in chronic inflammatory diseases in industrialized populations.

Food Additive Approval in the United States

The United States Food and Drug Administration (FDA) defines a food additive as “any substance the intended use of which results or may reasonably be expected to result directly or indirectly in its becoming a component or otherwise affecting the characteristics of any food”. In order for a novel food additive to be approved in the U.S., a food additive approval petition (FAP) must be submitted to the FDA. The identity of the ingredient, the proposed use in the food system, the technical effect of the ingredient, a method of analysis for the ingredient in foods, information on the manufacturing process, and full safety reports must be defined in a FAP. For FDA approval of a FAP, the FDA evaluates the chemical composition of the ingredient, the quantities that would be typically consumed, acute and chronic health impacts, and other safety factors. The FDA reviews the petition prior to market approval of the additive.


Standardization of its derived products

ISO has published a series of standards regarding the topic and these standards are covered by ICS 67.220.
