Lycopene is an organic compound classified as a tetraterpene and a carotene. Lycopene (from the Neo-Latin Lycopersicon, the name of a former tomato genus) is a bright red carotenoid hydrocarbon found in tomatoes and other red fruits and vegetables.

Lutein (; from Latin luteus meaning "yellow") is a xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants, and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll, an excited form of chlorophyll which is overproduced at high light levels during photosynthesis.

chemical compound

Tocopherols (; TCP) are a class of organic compounds comprising various methylated phenols, many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was named tocopherol, from Greek and , that is 'to carry a pregnancy', with the ending -ol signifying its status as a chemical alcohol.

thumb|The red color of beets comes from betalain pigments. Betalains are a class of red and yellow tyrosine-derived pigments found in plants of the order Caryophyllales, where they replace anthocyanin pigments. Betalains also occur in some higher order fungi. They are most often noticeable in the petals of flowers, but may color the fruits, leaves, stems, and roots of plants that contain them. They include pigments such as those found in beets.

'''tert-Butylhydroquinone (TBHQ, tertiary butylhydroquinone, tBHQ') is a synthetic aromatic organic compound which is a type of phenol. It is a derivative of hydroquinone, substituted with a tert''-butyl group.

chemical compound

Ethoxyquin (EMQ) is a quinoline-based antioxidant used as a food preservative in certain countries and originally to control scald on pears after harvest (under commercial names such as "Stop-Scald"). It is used as a preservative in some pet foods to slow the development of rancidity of fats. Ethoxyquin is also used in some spices to prevent color loss due to oxidation of the natural carotenoid pigments.

Anoxomer is a food additive with E number E323. It is a non-digestible polymeric antioxidant. It was designed to allow the introduction of established antioxidants in a non-absorbable manner in order to avoid potential health risk associated with their digestion.

Indicaxanthin is a type of betaxanthin, a plant pigment present in beets, in Mirabilis jalapa flowers, in cacti such as prickly pears (Opuntia sp.) or the red dragonfruit (Hylocereus costaricensis). It is a powerful antioxidant.
