Allura Red AC is a red azo dye that goes by several names, including FD&C Red 40. It is used as a food dye and has the E number E129. It is usually supplied as its red sodium salt, but can also be used as the calcium and potassium salts. These salts are soluble in water. In solution, its maximum absorbance lies at about 504 nm.

Fumaric acid or trans-butenedioic acid is the chemical compound with the formula HO2CCH=CHCO2H. It is produced in eukaryotic organisms from succinate in complex 2 of the electron transport chain via the enzyme succinate dehydrogenase. It is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid. In fumaric acid the carboxylic acid groups are trans (E) and in maleic acid they are cis (Z). Fumaric acid has a fruit-like taste. The salts and esters are known as fumarates. Fumarate can also refer to the C4H2O2−4 ion (in solution).

Adipic acid or hexanedioic acid is the organic compound with the formula (CH2)4(COOH)2. From an industrial perspective, it is the most important dicarboxylic acid: About 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon. Adipic acid otherwise rarely occurs in nature.

Acesulfame potassium ( AY-see-SUL-faym), also known as acesulfame K (K is the symbol for potassium) or Ace K, is a calorie-free sugar substitute (artificial sweetener) often marketed under the trade names Sunett and Sweet One. In the European Union, it is known under the E number (additive code) E950. It was discovered accidentally in 1967 by German chemist Karl Clauss at Hoechst AG (now Nutrinova). In chemical structure, acesulfame potassium is the potassium salt of 6-methyl-1,2,3-oxathiazine-4(3H)-one 2,2-dioxide. It is a white crystalline powder with molecular formula C4H4KNO4S and a molecular weight of 201.24 g/mol.

Aspartame (E951) is a low-calorie artificial sweetener composed of two amino acids.

It is used as a sugar substitute in thousands of "sugar-free" or "diet" products, such as carbonated soft drinks, chewing gum, yogurts, and tabletop sweeteners, to provide sweetness without the calories of sugar.

Despite being one of the most rigorously tested food additives, its safety remains controversial. While major regulatory bodies like the FDA and EFSA deem it safe for the general public, the IARC has classified it as "possibly carcinogenic to humans" (Group 2B). It must also be avoided by individuals with the genetic condition phenylketonuria (PKU).
