Description：
Orange powder, 0.1% water solution is yellow, odorless. Soluble in water, glycerin and propylene glycol, slightly soluble in ethanol, insoluble in oil and fat. 21 when the solubility is: 11. 8% (water), 3% (50% ethanol). Heat resistance, acid resistance, light resistance and salt tolerance were good for citric acid and tartaric acid is stable, but the oxidation resistance is poor. In case of alkali red, restore fading. Maximum absorption wavelength of 428nm + 2nm. Rat by mouth LD50 than ADI0, 2000mg/kg ~ 7.5mg/kg (FAO/WHO, 1994).
