What’s Canthaxanthin Powder?
Canthaxanthin is a carotenoids that is used as a dye that makes carrots orange. It is found naturally in many foods like carapace, fish, algae and other organisms. It is related to the carotenoids that give vegetables and fruits their orange color. This is often used in the coloring of drinks, sauces, meat and other food, which can make egg yolks more bright red, animal meat ruddy. Canthaxanthin has a substantial commercial market in aquaculture, poultry production, and cosmetic and nutraceutical industries. Canthaxanthin as a feeding additive is an international practice.
Studies have found that only a small fraction of the Canthaxanthin in food is absorbed and most of it is excreted directly from the body, depending on the amount of fat in the food. In animals, the absorption rate is only 3 to 8 percent. In humans, the absorption rate is between 9 and 34%. Generally, the residual amount in animal meat is very low and will not have any effect on the human body.
Canthaxanthin is more used as a feed additive, which can be extracted naturally or synthesized artificially. Because synthetic is more economical than natural extraction. When used as a feed additive, it’s basically synthetic, as we supplied in Rainbow Feeding. By the effective control of the production process, Rainbow Feeding has enough trans canthaxanthin to guarantee well pigmentation effect. By precise synthesis process and purification processing, our product has high purity and fewer by-products, which greatly reduce the chance of competitive absorption, further ensuring the pigmentation effect. We have optimized the extraction process to increase carotenoid content. The temperature was optimized to maximize the extraction efficiency by reducing the solvent’s viscosity. In addition, extraction times were optimized to optimize the carotenoid content. The product can be added directly to the water where the small particles are absorbing water and releasing the active ingredient canthaxanthin. It can disperse in cold water and rapidly to form a fine dispersion of the active ingredient canthaxanthin.

Benefits of Canthaxanthin For Feeding
Adding color to food is its biggest use, and it has many more benefits. Canthaxanthin is used to reduce sensitivity to sunlight (photosensitivity) experienced by people who have a rare genetic disease called erythropoietic protoporphyria (EPP). In these people, sunlight can cause skin reactions such as rash, itch, and eczema. Canthaxanthin has been shown to prevent cancer in the eyes and canthaxanthin can also prevent vitiligo and other skin diseases.
Canthaxanthin is permitted in fresh eggs and animal feeds in many countries. In addition, it is permitted in fish feeds according to the JECFA (JECFA) recommendations. It is allowed in salmon, trout, and poultry feeds according to EU regulations. However, the amount in egg-laying hens’ feeds is lower than the limit for other poultry.
