Astaxanthin Bulk Powder

What is Astaxanthin Bulk Powder?

Astaxanthin Bulk Powder is a keto carotenoid with a chemical structure: four isoprenes linked by a conjugated double bond and two isoprenes linked at each end in a six-membered ring. Astaxanthin has three optical isomers. The difference between the three optical isomers is in the stereoisomer of all-trans astaxanthin. 

Racemic astaxanthin powder bulk had the lowest antioxidant activity, D-Astaxanthin had the strongest free radical scavenging ability, and L-Astaxanthin had a stronger inhibitory effect on lipid peroxidation and immune activity. In addition to its antioxidant activity, astaxanthin also has anti-inflammatory and anti-diabetic properties. 

Furthermore, bulk astaxanthin powder is the only carotenoid that can penetrate the blood-brain and blood-retina barriers and have positive effects on the central nervous system and brain function. Therefore, astaxanthin is widely used in food, healthcare, cosmetics, and feed additives.

Is astaxanthin bulk powder safe?

Astaxanthin has been deemed safe by the U.S. Food and Drug Administration and the European Commission, and a range of health benefits from astaxanthin is now widely available and commercially promoted.

Bioavailability of Astaxanthin:

The human body cannot synthesize astaxanthin on its own and needs to be obtained from the diet. Difficult to absorb due to severe influence of dietary components. bulk astaxanthin powder can be absorbed when consumed with oily substances. Astaxanthin that enters the body with food binds to bile acids, phospholipids, and lipases in the small intestine and is released from food. After ingestion, astaxanthin enters the skin and brain, where it accumulates in the liver.

Applications of Astaxanthin Bulk Powder in Aquaculture:

Astaxanthin has long been added to fish feeds as a natural pigment. Used to farm salmon, snapper, and some ornamental fish. In recent years, more and more studies have found that astaxanthin has positive effects on weight gain and immune response in aquatic animals. Its application range is extended to crustaceans and some commercial fish. Carotenoids are closely related to a large number of physiological functions of plants and animals. The color of most aquatic animals and animal tissues is attributed to the presence of various carotenoids. As the main carotenoid in aquatic animal tissues, it has pigmentation, antioxidant and anti-stress effects.

1. Effects on the coloring function of aquatic animals

Adding astaxanthin powder bulk to feed can improve the coloring ability of fish and crustaceans and the astaxanthin in tissues

element concentration.

2. The effect of vegans on the antioxidant function of aquatic animals

Astaxanthin reacts with fat to form astaxanthin esters. It can effectively inhibit the chemical reaction of intracellular oxygen free radicals and unsaturated fatty acids. Therefore, the oxidative damage and inflammatory reaction of DNA can be reduced, and the immune response of the body can be improved. At the same time, it is easy to penetrate the biofilm with minimal damage to the membrane, so that the biofilm and fatty acids can be protected from lipid peroxidation.

3. Has the ability to resist stress and disease in aquatic animals

What are the preparations of astaxanthin?

1. Fat-soluble preparations

At present, the basic dosage forms of astaxanthin as a nutritional product are "oil suspension" and "oleoresin". "Oil suspension" refers to the suspension of astaxanthin in edible oil to form a suspension system. The content of astaxanthin in the suspension is generally 20% to 30%. "Oleoresin" means the extract of astaxanthin after it has been extracted and evaporated to remove the solvent.

2. Inclusion of complex

Scholars at home and abroad have carried out many studies on improving the water solubility and stability of astaxanthin, among which the addition of stabilizers is mainly used to form inclusion complexes.

3. Microcapsules

Microencapsulation technology refers to the use of natural or synthetic polymer materials to encapsulate dispersed solid, liquid, or gas materials in a tiny airtight capsule. The process of encapsulation is called microencapsulation, and the tiny particles formed are called microcapsules.

4. Nanoformulations

Astaxanthin is delivered by nano-formulations such as nano-emulsion composite systems, nanoparticles, self-emulsifying carriers, and nano-self-emulsifying carriers.
