Lycopene occurs as the major (85-90%) pigment (Fig. 1) in red tomatoes, Lycopersicum esculentum. The other pigments are ^-carotene (10-15%) with small quantities of about 10 other carotenoids. In spite of the fact that large quantities of lycopene are available in the waste from the tomato-processing industry, colorants containing lycopene were not commercially available. This was probably due to the belief that lycopene was susceptible to degradation by oxidation and light. But recently a combination of better manufacturing practices, and the development of a tomato cultivar particularly high in lycopene led to the commercialization of lycopene as a food colorant. Preparation of lycopene extracts from tomatoes is relatively simple, involving an alkali saponification and extraction with a mixture of solvents such as acetone and hexane. The acetone can be removed by washing with water and the hexane by vacuum treatment, leaving a relatively pure lycopene extract. The extract would, of course, contain the other carotenoids in the tomato. Commercialization probably was also helped by the health aspects because it may be an efficient in vivo radical scavenger. Lycopene preparations are being marketed as a neutraceutical and as a food colorant. Colorant preparations containing lycopene are currently not allowed in the United States.
