Legally the term has been referred to as “any substancethe intended use of which results or may reasonably be expected to resultdirectly or indirectly in its becoming a component or otherwise affecting thecharacteristics of any food.” (FDA)Additives are useful in controlling such things as decomposition anddeterioration, nutritional losses, loss of functional properties and aestheticvalue, but may not be used to disguise poor quality. This is suggested by theworld book encyclopedia F volume 7 page 302 of 1991.Their use is due to subject to regulation in the 1958 Food AdditivesAmendment to the food, drug and cosmetic (FD&C) act (USA) with exceptionsfor prior sanctioned items and generally regarded as safe (GRAS) substances.Encyclopedia Britannica volume 17 of 1768 on page 448 gives nutrients,colorings, flavorings, flavor enhancers and antimicrobial preservatives asexamples of food additives.Flavor enhancersEncyclopedia Britannica volume 17 of 1768 on page 448 states that “flavorscan also be influenced by the addition of a flavor enhancer such asmonosodium glutamate, which intensifies perception of flavor.” Flavorenhancers do not give food a flavor but intensify flavors already in food butthey could themselves be tasteless.
