Apa Itu Natural Astaxanthin Oleoresin 5/10% (Haematococcus Oil Resin)? Aplikasi, Dosis, Alternatif & Spesifikasi

Astaxanthin, chemically known as 3,3′-dihydroxy-4,4′-diketo-β, β′-carotene, is a naturally occurring ketocarotenoid and the highest-level product of carotenoid synthesis. Its chemical formula is C40H52O4, molecular weight is 596.84, CAS number is 472–61–7, and EINECS number is 207–922–7. The molecular structure of astaxanthin contains two β-ionone rings and eleven conjugated double bonds. It appears as a dark pink to dark purple solid and possesses unique lipophilic properties. Astaxanthin is widely found in nature, including in most crustaceans and salmonid fishes, the leaves, flowers, and fruits of plants, and the feathers of flamingos. The main sources of astaxanthin include Haematococcus pluvialis, Phaffia rhodozyma, and by-products from shrimp and crab processing. Astaxanthin exists in nature mainly in three stereoisomeric forms—left-handed (3S,3'S), right-handed (3R,3'R), and meso (3R,3'S). Among these, natural astaxanthin is predominantly the left-handed isomer, which possesses the highest biological activity and antioxidant capacity. In contrast, synthetic astaxanthin is a mixture of the three stereoisomers (approximately 25% left-handed, 25% right-handed, and 50% meso), exhibits very low antioxidant activity, and is fundamentally different from natural astaxanthin . As the strongest known natural antioxidant in nature, astaxanthin is known as the "King of Antioxidants," with antioxidant capacity far exceeding that of common antioxidants such as vitamin C, vitamin E, and β-carotene. Research has shown that natural astaxanthin's free radical scavenging capacity is 550 times that of vitamin E, with 2.3 times higher peak plasma concentration and 40% longer half-life than synthetic astaxanthin.

Astaxanthin is known as the "King of Antioxidants" and the "Super Antioxidant," occupying a rapidly rising core position in global dietary supplements, functional foods, cosmetics, and aquaculture feed. Its most prominent core advantages include the strongest known natural antioxidant capacity, multi-target synergistic anti-aging mechanisms, multiple health benefits, good safety, and continuously optimized production processes. 1 The strongest natural antioxidant capacity Astaxanthin is one of the strongest known natural antioxidants in nature. Research has shown that natural astaxanthin's free radical scavenging capacity is 550 times that of vitamin E, 6,000 times that of vitamin C, 40 times that of β-carotene, and approximately 20–30 times that of coenzyme Q10 [11†L20-L21]. Its unique molecular structure—two β-ionone rings and eleven conjugated double bonds—endows it with exceptional singlet oxygen quenching capacity and free radical scavenging activity, enabling it to protect both the interior and exterior of cell membranes from oxidative damage. 2 Multi-dimensional synergistic anti-aging mechanism Traditional research held that the anti-aging effect of astaxanthin mainly relies on its direct antioxidant mechanism. However, a 2025 systematic review published in the Journal of Future Foods points out that astaxanthin's core anti-aging effect is achieved through a multi-dimensional collaborative biological mechanism network that goes beyond direct antioxidation. Key mechanisms underlying its anti-aging potential include enhancing mitochondrial function and biogenesis to counteract age-related energy decline, regulating key epigenetic modifications associated with the aging process, maintaining extracellular matrix homeostasis crucial for tissue integrity during aging, and modulating gut microbiome homeostasis, increasingly recognized as a key player in healthy aging. Collectively, these interlinked mechanisms form a comprehensive protective network through which astaxanthin effectively mitigates senescence across multiple tissues and organs susceptible to age-related decline. 3 Multiple health benefits Based on its multi-dimensional bioactivity, the potential health benefits of astaxanthin include: potent antioxidant and anti-inflammatory effects, improved exercise endurance and muscle function, improved skin condition (anti-photoaging, whitening, repair), support for cardiovascular health, vision protection (anti-cataract, anti-macular degeneration), enhanced immunity, and promotion of neurological health. Human clinical studies have confirmed that daily supplementation of 4–12 mg of Haematococcus pluvialis-derived astaxanthin for 10–16 weeks produces significant anti-UV skin health benefits. 4 Excellent safety and bioavailability Astaxanthin is a natural component found in many foods and has received FDA GRAS certification in the United States, allowing its use as a safe dietary supplement and food ingredient. Within the recommended dosage range (4–24 mg per day), astaxanthin has shown good tolerability, with no reports of serious adverse reactions. In recent years, the application of novel delivery technologies such as nanoencapsulation, microencapsulation, and liposomes has significantly improved the oral bioavailability of astaxanthin, addressing the bottleneck of poor absorption traditionally associated with the high lipophilicity of astaxanthin. The addition of advanced extraction processes such as supercritical CO2 extraction can also improve yield, purity, and cost-effectiveness, thus enhancing market competitiveness. 5 Continuous iteration and upgrading of production processes Astaxanthin production processes have evolved from chemical synthesis and traditional microalgae extraction to synthetic biology-driven microbial fermentation. Professor Chen’s team at Nanjing Tech University implanted the full synthetic pathway for left-handed astaxanthin from Haematococcus pluvialis into the genome of Yarrowia lipolytica, integrating membrane engineering, promoter engineering, scaffold protein fusion expression, and directed evolution of enzymes to overcome bottlenecks in yeast-based astaxanthin synthesis [9†L9-L10]. Fermentation requires only 5 days, with stable yields above 2.0 g/L, and the product contains up to 3% astaxanthin. Over 1,000 mu of Haematococcus pluvialis cultivation base, with pure astaxanthin annual production capacity expected to exceed 17.68 tons, accounting for over 40% of the global market share. ZEAL Biotech has completed a 3,000-ton-per-year astaxanthin project using the Phaffia rhodozyma fermentation route, achieving high yield and low cost.
