Astaxanthin Powder Usage and Synthesis.

Astaxanthin is currently widely used as a functional pigment in aquaculture, food, cosmetics and other fields, mainly used as a feed additive for fish, shrimp, crabs and other crustaceans, as well as poultry, to improve the reproductive capacity and survival rate of livestock and fish, to improve the health status, optimise the body colour and meat quality. Natural astaxanthin has been used as a food additive for food colouring, preservation and nutritional enhancement.

Studies have shown that astaxanthin helps to preserve the freshness of trout fillets.

In recent years, with the astaxanthin biological function research and pharmacological efficacy experiments continue to deepen, astaxanthin because of its cardiovascular disease, cancer, metabolic syndrome, diabetes, neurodegenerative diseases, ophthalmological diseases, skin diseases and other diseases of the prevention and treatment of the effect and by the scientific community has been a great deal of attention, indicating that astaxanthin in the field of pharmaceuticals, nutraceuticals and other areas of potential application of great value and broad prospects for development. It shows that astaxanthin has great potential application value and broad development prospect in the fields of medicine and health products.

Uses of Astaxanthin.

Natural astaxanthin, also known as astaxanthin, is an extremely valuable health raw material, which can be used to develop natural, healthy products for boosting immunity, antioxidant, anti-inflammatory, eye and brain health, and regulating blood lipids.

At present, it is mainly used as raw material for human advanced health food and medicine; feed additive for aquaculture (currently mainly salmon, trout and salmon) and poultry farming; and cosmetic additive.

It can significantly improve the immunity of the human body, and has significant anti-fatigue effects due to its ability to bind non-specifically to skeletal muscle, effectively removing free radicals generated by exercise in muscle cells and strengthening oxygen-demanding metabolism.

It is the only carotenoid that can pass the blood-brain barrier and has a real anti-aging effect. Effective antioxidant is the basis of all beauty activities, due to its super antioxidant effect.

Characteristic of Astaxanthin.

At present, the methods of preparing astaxanthin at home and abroad can be divided into two main categories: chemical synthesis and biosynthesis. The chemically synthesised astaxanthin is a mixture of three structures levulose: racemic: dextrose (1:2:1). Chemically synthesised astaxanthin is mainly used as an industrial dye, but is not permitted to be used in the field of food and medicine. Biosynthesised astaxanthin is allowed to be used in food and medicine.

Certain microalgae, fungi, bacteria and specific species of plants in nature have the ability to synthesise astaxanthin. Synthetic levulin astaxanthin accounts for more than 90 per cent of the total astaxanthin. Chemical synthesis of astaxanthin is divided into total synthesis method and semi-synthetic method.

The total synthesis method of astaxanthin uses chemical raw materials as raw materials and obtains astaxanthin through chemical synthesis reaction.

Semi-synthetic method is the use of carotenoids such as keratine, lutein and zeaxanthin as raw materials to prepare astaxanthin.

Product Method of Bulk Astaxanthin Powder.

Step 1, Fife yeast body wall-breaking: the use of dimethyl sulfoxide on the Fife yeast body wall-breaking, wall-breaking conditions: bacteria and dimethyl sulfoxide according to the mass volume ratio, that is, g / ml, the ratio of 1/2, at a temperature of 55 ° C, wall-breaking 5min;

Step 2, acetone crude extraction of astaxanthin: after breaking the wall with acetone according to the material-liquid ratio of 1:15 extraction, said material-liquid ratio for the body of fife yeast and acetone by mass volume ratio, that is, g / ml, extracted for 2 times, combined with the extraction solution, low-temperature rotary evaporation to remove the acetone, the residual components for dimethyl sulfoxide dissolved astaxanthin crude extract, the residual components that is astaxanthin a crude extract;

Step 3, degreasing and removal of low-polarity carotenoids: petroleum ether extraction of astaxanthin crude extract, the extraction ratio of astaxanthin crude extract: petroleum ether volume ratio of 1:2, the number of times the extraction is 2 times, discarding the upper layer of petroleum ether, collect the lower layer of the solution, the lower layer of the solution that is astaxanthin crude extract for the second time;

Step 4, remove dimethyl sulfoxide: astaxanthin second crude extract and pre-cooled to 4 ℃ saturated sodium chloride aqueous solution mixed by volume ratio 1:3.5, the mixture with ethyl acetate for extraction, the amount of ethyl acetate for astaxanthin second crude extract of 3 times the volume; collection of ethyl acetate phase, low-temperature rotary evaporation to dryness, the production of astaxanthin powder with high purity;

Step 5, crystallisation: the astaxanthin powder produced in step 4, add methylene chloride to dissolve, to dissolve the astaxanthin powder until the end, and then add methanol to the solution until the crystals precipitate until it is left to stand, methylene chloride naturally evaporates, so that the astaxanthin crystals precipitate; at 4 ℃, 9961 × g centrifugation conditions, centrifugation for 10min, collect the bottom of the crystals that is astaxanthin.
