Storage conditions
Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Packaging is sealed. It should be stored separately from acids and edible chemicals. The storage area should be equipped with suitable materials to contain spills.
Stability
A carotenoid pigment. Dark purple crystal or crystalline powder. Melting point is about 210 ° C (decomposed). Unstable to oxygen and light. Store in a light-shielding container filled with an inert gas. Dissolved in chloroform (10%). Slightly soluble in vegetable oil (0.005%), acetone (0.03%). Insoluble in water, ethanol and propylene glycol. Stable industrial products are in the form of solutions dissolved in grease or organic solvents, or in the form of water-dispersible orange to red powder or granules. After coloring, the hue is not affected by pH, and it is quite stable to sunlight, and it is not easy to fade.
Natural products are found in certain mushrooms, crustaceans, fish, algae, eggs, blood, liver, etc.
