Natural Astaxanthin Powder

 

There are generally three biological sources of natural astaxanthin powder: waste from the aquatic product processing industry, Phaffia rhodozyma and Haematococcus pluvialis.

 

Among them, the astaxanthin content in the waste is low, and the extraction cost is high, making it unsuitable for large-scale production. The average astaxanthin content in natural Phaffia rhodozyma is only 0.40%. In contrast, the astaxanthin content in Haematococcus pluvialis is 1.5% to 3.0%, and it is the most commonly used extraction source.

 

Research shows that the accumulation rate and total production of astaxanthin in Haematococcus pluvialis is higher than that of other green algae, and the ratio of astaxanthin and its esters contained in Haematococcus pluvialis (about 70% of monoester, (25% diester and 5% monomer) is very similar to the ratio of aquaculture animals themselves.

 

This is an advantage that astaxanthin extracted through chemical synthesis and utilization of Phaffia rhodozyma and others does not have.

 

In addition, the structure of astaxanthin in Haematococcus pluvialis is mainly 3S-3'S, which is basically the same as the structure of astaxanthin in aquatic products such as salmon; while the structure of astaxanthin in Phaffia rhodozyma is 3R- 3 R type, Haematococcus pluvialis is also recognized as the best organism in nature to produce natural astaxanthin.

1. Chemical structure
In terms of structure, due to the optical rotation of the hydroxyl groups (-OH) at both ends, astaxanthin has three types: left-handed, racemic, and right-handed (3S-3'S, 3R-3'S, 3R-3'R).

 

There are three structural isomeric forms of astaxanthin, among which synthetic astaxanthin is a mixture of three structures of astaxanthin (25% left-handed, 25% right-handed, and about 50% racemic), which is rarely resistant to oxidative activity, but natural astaxanthin has a 100% left-handed (3S-3'S) structure, which has the strongest biological activity and good antioxidant properties.

 

2. Antioxidant properties:
The stability and antioxidant activity of synthetic astaxanthin are also lower than that of natural astaxanthin. Since the hydroxyl groups (-OH) at both ends of the astaxanthin molecule can be esterified, its stability is different. Natural astaxanthin powder is 90% The above esterified form exists and is therefore more stable.

 

Synthetic astaxanthin exists in a free state, so its stability is different. Synthetic astaxanthin must be embedded to be stable. Since synthetic astaxanthin has only about 1/4 of its left-handed structure, its antioxidant properties are only about 1/4 of natural astaxanthin.

 

3. Application effects
The biological absorption effect of synthetic astaxanthin is also worse than that of natural astaxanthin, and it cannot be converted into its natural configuration in the body. Its coloring ability and biological potency are much lower than that of natural astaxanthin powder of the same concentration.

 

4. Biosecurity
When using chemical means to synthesize astaxanthin, impurity chemicals will inevitably be introduced, such as non-natural by-products produced during the synthesis process, which will reduce its bioavailability safety. Therefore, it cannot be used in the human market.

 

 

1. Antioxidant properties
Astaxanthin is an excellent antioxidant. Its ability to quench the activity of reactive oxygen species in cells and scavenge cellular free radicals is more than 10 times higher than β-carotene and more than a hundred times stronger than vitamin E.

 

2. Enhance immunity
Natural astaxanthin powder can increase the number of immune cells and inhibit cytokine storm or inflammatory storm caused by excessive immune response, thereby enhancing the body's immunity.

 

3. Anti-aging
Ultraviolet radiation is an important cause of epidermal aging, and astaxanthin can effectively remove oxygen free radicals in cells and reduce the accumulation of senescent cells, protecting skin health and delaying skin aging.

 

 

4. Eye protection
The retina has high concentrations of polyunsaturated fatty acids and high concentrations of oxygen, and the central nervous system is rich in unsaturated fatty acids and iron, both of which are extremely susceptible to oxidative damage. Astaxanthin can cross the blood-brain barrier and quench damaging reactive oxygen species, thereby maintaining eye health.

 

5. Prevent cardiovascular disease
Research shows that the oxidation of low-density lipoprotein (LDL) is an important cause of arteriosclerosis, while high-density lipoprotein (HDL) in the blood has the opposite effect, which can prevent the occurrence of arteriosclerosis.

 

Studies have shown that natural astaxanthin powder can significantly increase HDL and lower LDL in the body. Therefore, it is speculated that astaxanthin can reduce the oxidation of apolipoprotein and can be used to prevent arteriosclerosis, coronary heart disease and ischemic brain damage.

 

6. Inhibit diabetic nephropathy
80% of people with diabetes will develop kidney damage within 5 years. Astaxanthin is the only substance discovered so far that can effectively prevent diabetic kidney damage. Astaxanthin mainly works by directly protecting the glomerular basement membrane and preventing the production of hyperglycemia. free radicals that damage the basement membrane.

 

It can also fight against free radicals in renal tubular epithelial cells, protect the normal transport of glucose and phosphorus in renal tubular cells, thereby preserving important substances such as ATP and sodium-potassium ATPase, ensuring that renal blood flow is not affected, and reducing the risk of proteinuria. produce.
