毒性A food color formerly approved for use in the United States and Europe. It was used primarily in jams and marmalades, maraschino cherries, pickles and relishes, etc. The LD50 in rats is 150 mg/kg, i.p., and 600 mg/kg, p.o. Erythrosine has a variety of actions in vitro due in large measure to its ability to affect biological membranes and lipophilic sites of enzymes. Such data have led to the hypothesis that erythrosine could be neurotoxic, but both clinical and preclinical data have suggested that erythrosine is not likely to be neurotoxic at doses that might be encountered. Two other toxicological issues have been raised with this food color. It has been suggested to be a potential, if weak, carcinogen, and it may also contribute to potential thyroid toxicity resulting from release of iodine.
