# Microalgal carotenoids Microalgae-derived carotenoids — natural astaxanthin from Haematococcus pluvialis and beta-carotene from Dunaliella salina — produced as high-concentration oleoresins and supplement ingredients by dedicated cultivators in the USA, India, Austria, Iceland and Israel. Source: https://en.bioecon.ru/technology/microalgal-carotenoids/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: EU Novel Food & FDA DSHEA dietary-supplement rules | OECD: Marine bioeconomy | Regulator: FDA (USA), EFSA (EU), NMPA (China)] Microalgal carotenoids are the high-value pigments microalgae accumulate under stress — chiefly natural astaxanthin from *Haematococcus pluvialis* and natural beta-carotene from *Dunaliella salina*. Cyanotech runs a 96-acre cultivation farm on Hawaii's Kona Coast with more than 40 years of microalgae experience; Algalíf in Iceland markets the Astalíf™ oleoresin line at 5%, 10%, 15% and 20% astaxanthin, having launched the world's first 15% oleoresin and, in April 2026, the Astalíf™ 20 benchmark; BDI-BioLife Science produces ASTAFIT® astaxanthin "Made in Austria"; and Cyanotech's BioAstin® is sold at an industry-leading 12 mg of Hawaiian astaxanthin per serving. The value is the antioxidant potency and pigment purity of microalgae-grown carotenoids, sold as B2B oleoresins and finished supplements. The key directions of microalgal carotenoids are: 1. **Haematococcus astaxanthin (Haematococcus Astaxanthin):** two-stage cultivation of *Haematococcus pluvialis* (green growth → red cyst stress) yielding natural astaxanthin (Cyanotech BioAstin, BDI ASTAFIT, Algalíf Astalíf). 2. **Dunaliella beta-carotene (Dunaliella Beta-Carotene):** high-salinity open-pond cultivation of *Dunaliella salina* for natural beta-carotene (all-trans / 9-cis mix). 3. **High-concentration oleoresins (Astaxanthin Oleoresin):** supercritical-CO₂ extraction and standardization to 5–20% astaxanthin oleoresins (Algalíf Astalíf™ 5/10/15/20, world's first 15% and 20% benchmarks). 4. **Controlled microalgae cultivation (Microalgae Photobioreactor):** closed photobioreactor and raceway cultivation using Iceland geothermal energy and Hawaiian/Kona coastal conditions for reproducible carotenoid content. ### Sectoral value chain ``` [microalga strain (Haematococcus / Dunaliella)] ──> [green-cell cultivation] ──> [stress induction (astaxanthin)] │ (light / N-starvation) │ ▼ [5–20% oleoresin + supplement] <─── [supercritical CO₂ extraction] <─────┘ ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Strain & inoculum** | axenic *Haematococcus* / *Dunaliella* seed culture | **In:** master strain. **Out:** scaled inoculum. | | **Green-cell cultivation** | photobioreactor / raceway biomass build-up | **In:** inoculum, CO₂, sunlight. **Out:** green biomass. | | **Stress induction** | nitrogen starvation + high light drives cyst-stage astaxanthin | **In:** green biomass. **Out:** red cyst biomass. | | **Harvest & disruption** | dewatering and cell-wall disruption to release carotenoids | **In:** red biomass. **Out:** disrupted cell paste. | | **Extraction** | supercritical CO₂ extraction to crude oleoresin | **In:** cell paste. **Out:** astaxanthin oleoresin. | | **Formulation** | standardization to 5–20% oleoresin and finished supplements | **In:** oleoresin. **Out:** softgels, gummies, B2B ingredient. | Cross-cutting technologies of the sector: - **Two-stage Haematococcus cultivation (Two-Stage Haematococcus Cultivation):** separated green-growth and red-induction phases for high astaxanthin yield. - **Supercritical CO₂ extraction (Supercritical CO₂ Extraction):** solvent-free recovery of carotenoid oleoresin at food-grade purity. - **Geothermal / tropical cultivation siting (Geothermal / Tropical Siting):** Iceland geothermal energy (Algalíf) and Hawaiian coastal climate (Cyanotech) for low-cost controlled cultivation. --- ## US The United States anchors natural astaxanthin production through its long-established Hawaiian microalgae industry. ### Cyanotech Kona farm, Nutrex Hawaii, university microalgae research - **Cyanotech (Hawaii):** a world leader in microalgae-based nutrition, operating a 96-acre farm on Hawaii's Kona Coast with more than 40 years of cultivation experience; its BioAstin® Hawaiian Astaxanthin® is a leading natural astaxanthin brand, sold via its Nutrex Hawaii subsidiary (a 12 mg-per-serving gummy format launched in 2024) and quoted OTCQB:CYAN. - **University microalgae research:** US universities (e.g. UC San Diego, Arizona State) underpin the strain-engineering and physiology science base for Haematococcus astaxanthin accumulation. - **Dietary-supplement market:** the US DSHEA framework anchors the largest natural-astaxanthin supplement market, driving finished-format innovation (softgels, gummies). --- ## CN China is a large and fast-growing producer of natural astaxanthin, but the two leading candidate firms could not be source-confirmed against a 2026 live source within the capped search, so this block is qualitative. ### Domestic Haematococcus cultivation, Yunnan and Hubei regions - **Domestic cultivation base:** Chinese producers cultivate *Haematococcus pluvialis* across inland regions (Yunnan, Hubei/Jingzhou) and are scaling natural-astaxanthin capacity for both nutraceutical and aquaculture-feed-pigment use. - **Regulatory frame:** dietary-supplement and feed-additive oversight sits with China's market-regulation and agriculture authorities, framing the domestic carotenoid ingredient trade. - **Caveat:** company-specific 2026 facts for Yunnan Alphy Biotech and Jingzhou-region producers returned only off-target or generic results in the capped search; this block intentionally carries no unconfirmed firm. --- ## EU Europe pairs an Austrian astaxanthin producer with an Icelandic leader to form the continent's dedicated natural-carotenoid supply base, extended by the French Solabia Group's Israeli desert-cultivation arm. ### BDI-BioLife Science Austria, Algalíf Iceland, Solabia-Algatech, EU Novel Food - **BDI-BioLife Science (Austria):** produces ASTAFIT® astaxanthin from *Haematococcus pluvialis* under its "Red Diamond®" seal of quality for astaxanthin "Made in Austria" (food and supplement lines); the parent BDI-BioEnergy International was acquired in 2024 by EOSS Industries, Kanzler Verfahrenstechnik and the Rieckermann Group. - **Algalíf (Iceland):** a global leader in sustainable natural astaxanthin cultivating under Iceland's geothermal energy; its Astalíf™ oleoresin runs at 5%, 10%, 15% and 20% astaxanthin, including the world's first 15% oleoresin and the April-2026 Astalíf™ 20 high-concentration benchmark. - **Solabia-Algatech (Kibbutz Ketura, Israel — Solabia Group, France):** cultivates *Haematococcus pluvialis* in closed photobioreactors under Arava desert sunlight for its AstaPure® astaxanthin line, sold as oleoresin, a 3% whole-algae powder and finished gummy formats, alongside BioGlena® *Euglena* beta-glucan. - **EU Novel Food & EFSA:** microalgae carotenoid ingredients in the EU are placed under the Novel Food framework and EFSA health-claim rules, shaping the European supplement ingredient market. --- ## Leading companies and research institutes | Company / Institute | Country | Key products / platforms | Tech features | Status 2026 | |:---|:---|:---|:---|:---| | **Cyanotech** | 🇺🇸 USA | *BioAstin® Hawaiian Astaxanthin®* | 96-acre Kona farm, OTCQB:CYAN, 40+ yrs | Commercial | | **Parry Nutraceuticals** | 🇮🇳 India | *organic spirulina & microalgae carotenoids* | EID Parry division, large-scale microalgae | Commercial | | **BDI-BioLife Science** | 🇦🇹 Austria | *ASTAFIT® / Red Diamond® astaxanthin* | Haematococcus, "Made in Austria" | Commercial | | **Algalíf** | 🇮🇸 Iceland | *Astalíf™ 5/10/15/20% oleoresin* | geothermal cultivation, world-first 15% & 20% | Commercial | | **Algatech** | 🇮🇱 Israel | *AstaPure® astaxanthin, BioGlena® beta-glucan* | Arava desert photobioreactors, Solabia Group | Commercial | --- ## Tech stack and innovations The stack pairs two-stage microalgae cultivation with solvent-free extraction and high-concentration oleoresin standardization. 1. **Two-stage Haematococcus cultivation (Two-Stage Haematococcus Cultivation):** - *Haematococcus pluvialis* is grown as green motile cells for biomass, then shifted to nitrogen-starvation and high light to induce the red resting cyst that accumulates astaxanthin. - Cyanotech (Hawaii), BDI-BioLife (Austria) and Algalíf (Iceland) each run their own controlled-cultivation geometry (open raceways, closed photobioreactors) for reproducible carotenoid content. 2. **Supercritical CO₂ extraction (Supercritical CO₂ Extraction):** - Harvested red biomass is dewatered, cell walls are disrupted, and carotenoids are recovered with supercritical CO₂ to a solvent-free food-grade oleoresin. - The output is a standardized astaxanthin oleoresin that downstream brands formulate into softgels and gummies (e.g. Cyanotech's 12 mg-per-serving BioAstin gummy). 3. **High-concentration oleoresin formulation (Astaxanthin Oleoresin):** - Algalíf's Astalíf™ line is standardized to 5%, 10%, 15% and 20% astaxanthin, setting successive concentration benchmarks (world's first 15% oleoresin; Astalíf™ 20 launched April 2026). --- ## Value chains and production pipelines ### Industrial pipeline of microalgal carotenoids (FDA DSHEA / EU Novel Food / ISO 22000) ``` ┌───────────────────────────┐ ┌───────────────────────────┐ │ 1.
