Erythrosine

Description:

Erythrosine, also known as E127, is a synthetic red dye belonging to the xanthene class of compounds. It is primarily used as a food coloring agent, imparting a bright pink to red hue in various products, including candies, beverages, and baked goods. Erythrosine is soluble in water and exhibits a strong absorption in the visible spectrum, which contributes to its vibrant color. The chemical structure of erythrosine features a brominated xanthene backbone, which enhances its stability and color intensity. It is often used in conjunction with other colorants to achieve desired shades. While generally recognized as safe for consumption in regulated amounts, erythrosine has been subject to scrutiny regarding potential health effects, including concerns about hyperactivity in children and thyroid function due to its iodine content. Regulatory agencies, such as the FDA and EFSA, have established acceptable daily intake levels to ensure consumer safety. Overall, erythrosine is a widely utilized color additive in the food industry, valued for its vivid coloration and stability.

Erythrosine

CAS: 16423-68-0

Erythrosine is a fluorescent dye that is used in the detection of synchronous fluorescence and adsorption. It has been shown to be more sensitive than other methods, such as matrix effect or electrochemical impedance spectroscopy. Erythrosine has been shown to have genotoxic activity in hl-60 cells, as well as long-term toxicity. It also has analytical applications due to its ability to be used as a fluorescence probe for biological samples.
