citrus red no. 2

Citrus Red No. 2 is a synthetic dye that is used to color the skin of oranges and grapefruits. It is a mixture of two compounds: 1-(2,5-dimethylphenylazo)-2-naphthol (Sudan Red 7B) and 1-(4-diethylamino-2-methylphenylazo)-2-naphthol. The dye is applied to the fruit about 2-3 weeks before harvest. The dye is absorbed into the fruit and gives it a more uniform color. It is also believed to help prevent the fruit from becoming overripe. Citrus Red No. 2 has been studied extensively for its safety. The FDA has determined that it is safe for use on oranges and grapefruits at the recommended levels. However, some studies have shown that the dye may be carcinogenic in animals. More research is needed to determine if Citrus Red No. 2 is carcinogenic in humans. The dye is used because it helps to make the fruit more attractive to consumers and also helps to extend the shelf life of the fruit.'
