General description

Bixin is a carotenoid and the principal colouring component of Annatto food colouring (E160b), which has a long history of use in the food industry for the colouring of a wide range of food commodities.
Bixin is a methyl ester of a dibasic fatty acid. On treating with alkali, it is hydrolyzed to form water soluble norbixin. It is obtained in pure form from annatto seeds. Bixin is a carotenoid and estimated as yolk and skin pigmenter.

Bixin, also known as annatto, is a seed-specific pigment widely used in foods and cosmetics since pre-Columbian times. We show that three genes from Bixa orellana, native to tropical America, govern bixin biosynthesis. These genes code for lycopene cleavage dioxygenase

The most abundant water soluble natural food colors are betacyanins and anthocyanins. Similarly, lycopene, bixin, beta-carotene, and chlorophyll are water insoluble colors. Pure betanin, bixin, lycopene, chlorophyll, beta-carotene, and cyanidin-3-O-glucoside were isolated from Beta vulgaris, Bixa orellana,Lycopersicum esculentum, Spinacia oleracea

Singlet molecular oxygen (1O2) has been shown to be generated in biological systems and is capable of damaging proteins, lipids and DNA. The ability of some biological antioxidants to quench 1O2 was studied by using singlet oxygen generated by the
