Synthetic astaxanthin has many hazards

Using chemical means synthesized astaxanthin will inevitably introduced impurities chemical substances, such as non-natural byproducts generated during the synthesis, etc., will reduce the security of its bioavailability. 

Using chemical means synthesized astaxanthin will inevitably introduced impurities chemical substances, such as non-natural byproducts generated during the synthesis, etc., will reduce the security of its bioavailability. With the rise of natural astaxanthin, the management of the world to chemical synthetic astaxanthin is more and more strict. Currently, the chemical synthesis of astaxanthin (also known as astacin) has been banned from entering the health food market. Astaxanthin suppliers produce astaxanthin generally tend to develop the natural astaxanthin biological sources.

Astaxanthin is a red pigment widespread in organism, although astaxanthin is not commonly used in everyday life, but astaxanthin exists in many kinds of foods. Most crustaceans such as shrimp, lobster, crab and so on show up red color were caused by astaxanthin accumulation, in some fish such as salmon’s color is also the result of astaxanthin accumulating, the well-known ornamental fish red golden, discus, Flower Horn and blood parrot, the bright color scales also the result of the accumulation of astaxanthin. Astaxanthin is showing red color, when it is combined with a variety of light-absorbing protein, it can show a green, yellow, blue, and brown color. Now it has been proved that the crustaceans showing red when cooked is due to the nature of the protein changed, as well as caused by astaxanthin chromophore release. Black, red, blue and green are the result of astaxanthin and protein and chitin composite.

At present, the ornamental fish feed production enterprise technology sector is not comprehensive and in-depth understanding of astacin, there are existing some erroneous understanding, even do not know astaxanthin have isomers, error equivalent natural astaxanthin to synthetic astaxanthin, some enterprises do not know the difference between free and esterified astaxanthin, what’s more, is existing errors in environmental protection, safety awareness.

People have just a little knowledge about the pharmaceutical and chemical were know that, a lot of substance in nature are existing isomers, their formula are the same, but their spatial structure different, different spatial structure will mainly affect the physiological functions and distribution in animal tissues. Astaxanthin has stereoisomers and geometric isomers.

Currently, the production of astaxanthin (also known as super vitamin) mainly have artificially synthesized and obtained from organisms two ways. The main source of natural astaxanthin have two ways: the waste of aquatic products (prawns, crabs and other crustaceans), Phaffia yeast and microalgae (pluvialis algae). Synthetic astaxanthin is more difficult, compared to the natural astaxanthin, they are significant difference in the structure, physiological functions, application effects, etc.

In structure, natural astaxanthin is mainly the levoduction conformation, and the synthetic astaxanthin is a mixture of three kinds of configurations, and mainly are the racemic. In addition, synthetic astaxanthin in animal body can not be translated into the native conformation. In terms of physiological function, the stability and antioxidant activity of natural astaxanthin is significantly higher than synthetic astaxanthin. In the application effect, natural astaxanthin’s biological absorption effect and coloring effect is also superior to the synthetic astaxanthin, and entirely no side effects, can be widely used in aquaculture, poultry farming, human food and health supplementsHealth Fitness Articles, cosmetic raw material and human drugs and beasts medicines.
