What is Astaxanthin?
Astaxanthin is a natural keto-carotenoid and potent antioxidant widely used in nutrition, feed, and cosmetics. It is found in marine organisms such as salmon, shrimp, krill, crab, and especially in the microalgae Haematococcus pluvialis, the primary commercial source. Astaxanthin (CAS No. 472-61-7, molecular formula C₄₀H₅₂O₄, molecular weight 596.85) is also referred to as Algal Astaxanthin or Natural Astaxanthin. JaYoo Biotech supplies natural Astaxanthin extracted from Haematococcus pluvialis in 1%, 2%, 5%, and 10% specifications (UV method). The 1%, 2%, and 5% grades are deep red powders, while the 10% grade is a deep red oil. Natural Astaxanthin is poorly soluble in water but highly soluble in oils and organic solvents, supporting its high bioavailability in lipid-based formulations. Standard packaging is 20 kg per drum for global B2B distribution. As a leading Haematococcus pluvialis supplier in China, JaYoo Biotech provides high-quality Astaxanthin raw materials and offers OEM services for capsules, tablets, and customized supplement formulations for international brands and distributors.

Harvest the culture when optimal biomass and pigment concentration are achieved. - Dewatering
Remove excess water from the harvested slurry to concentrate biomass and enhance processing efficiency. - Primary Centrifugation
Centrifuge to separate microalgae cells from the culture medium, yielding concentrated biomass. - Purified Water Washing
Wash biomass with purified water to remove impurities and improve purity. - Secondary Centrifugation
Centrifuge a second time to further concentrate algae and enhance consistency. - Suspension with Pure Water
Resuspend biomass in purified water to facilitate filtration and ensure uniform processing. - Filtration
Filter to remove fine impurities and ensure consistent raw material quality before drying. - Spray Drying
Spray-dry the purified slurry to produce deep red Astaxanthin powder while preserving antioxidant activity. - Final Filtration
The dried powder undergoes final filtering to ensure uniform particle size and quality. - Inner Packaging
Seal Astaxanthin powder in protective inner packaging to prevent oxidation and moisture absorption. - Outer Packaging
Pack products in industrial bulk containers for transport and storage. - Product Quality Testing
Each batch is tested for Astaxanthin content, moisture, heavy metals, and microbiological safety to meet international standards. Identified products are stored in controlled warehouses before global shipment.
Astaxanthin Applications
Astaxanthin is a natural carotenoid with significant antioxidant activity and pigmentation properties, leading to its widespread use across various industries. In aquaculture, it is incorporated into feed for salmon, shrimp, and ornamental fish to enhance coloration and improve immune resistance. In poultry production, astaxanthin is used to produce orange-red egg yolks and to enhance egg nutritional value. Within the pet nutrition sector, astaxanthin is added to food and supplements to promote coat shine, eye health, and overall vitality in dogs, cats, and ornamental fish. The compound is also utilized in dietary supplements and functional foods as an antioxidant for daily health maintenance. Furthermore, astaxanthin is increasingly incorporated into cosmetics and skincare products for its antioxidative, skin-brightening, and UV-protective effects, as well as in the food industry as a natural colorant and functional ingredient. These diverse applications establish natural astaxanthin derived from Haematococcus pluvialis as a valuable ingredient for feed manufacturers, supplement brands, food producers, and cosmetic companies globally.
