Canthaxanthin, also known as β-carrot-4,4-dione, etc., is one of the five main carotenoids (lutein, astaxanthin, zeaxanthin, cantharidin, carotene). Deep purple crystal or crystalline powder, melting point about 210°C (decomposition), should be stored in a light-shielding container filled with inert gas, soluble in chloroform (10%), slightly soluble in vegetable oil (0.005%), acetone (0.03%) , Insoluble in water, ethanol, propylene glycol. The vegetables and fruits we usually eat contain this substance to varying degrees. Canthaxanthin has a similar antioxidant effect to other carotenoid compounds, and also has good coloring ability. Canthaxanthin has been widely used in the fields of food, nutrition, cosmetics and feed additives, and it plays a huge role.
Canthaxanthin naturally occurs in common soft-shelled turtles, fish, algae and insects, and is an important carotenoid, which is a functional coloring factor. Canthaxanthin is a coloring agent added to the feed. The main ingredients are canthaxanthin, corn starch, yellow dextrin, sucrose, ethoxyquinoline, ascorbyl palm fat, etc. It is mainly used for the coloring of egg yolk, edible poultry, frog fish and crustaceans. It is widely used in the feed industry and is suitable for adding to various batches, premixes, powders, granules and extruded materials.
Benefits of canthaxanthin
First, the color tone after coloring is not affected by the pH value, and it is also quite stable to sunlight and is not easy to fade.
Second, it can change the skin and fat of poultry. It is a chemically synthesized pigment, and the active ingredient is canthaxanthin. It is mainly added to poultry feed to increase the color and brightness of skin, feet, ketone bodies and eggs.
Third, canthaxanthin can also be used as an antioxidant to protect cells in animals from free radiation.
Canthaxanthin's advantages
Canthaxanthin plays a very good role in livestock and poultry farming:
1. Fluidity: The active ingredient canthaxanthin in canthaxanthin is evenly distributed in the starch-coated gelatin and carbohydrates, and becomes spherical or beaded small particles. This production process ensures the stability and excellent flowability of canthaxanthin.
2. Stability: canthaxanthin provides double protection for the active substance canthaxanthin to achieve the best stability, stabilizes canthaxanthin with antioxidants, and coats it in starch-coated gelatin. The high quality of canthaxanthin enhances the ability of canthaxanthin to resist external adverse factors and withstand harsh processing conditions.
3. Easy to mix: canthaxanthin can be easily mixed in poultry feed and distributed evenly. Cantharidin products have less dust, which is easy to operate and reduces environmental pollution.
