Supercritical Fluid Separation & Conjugated Polyene Stabilization
Carotenoids represent a complex class of tetraterpenoid chromophores characterized by an extensive conjugated polyene chain comprising 9 to 11 conjugated carbon-carbon double bonds. This conjugated backbone is simultaneously responsible for their remarkable photoprotective and singlet oxygen quenching capacity (>1 × 10⁸ M⁻¹s⁻¹) and their heightened thermodynamic vulnerability toward photo-oxidation, thermal cis-trans isomerization, and radical-mediated auto-oxidation.
At Shaanxi Torzi Biotech, our extraction architecture relies on state-of-the-art Supercritical Carbon Dioxide (scCO2) separation accompanied by subcritical ethanol as an eco-certified entrainer. By running at mild operating temperatures between 38°C and 45°C under high-pressure parameters (28 to 35 MPa), our facility eliminates the structural thermal degradation common to atmospheric solvent distillation. This ensures that the native all-trans configuration—which exhibits the highest biological activity and crystalline stability—is preserved at ratios exceeding 92% of total active fractions.
To overcome the natural lipophilicity and poor aqueous solubility of raw carotenoids in Swedish functional beverage and dairy lines, our engineering plant utilizes spray-dried modified starch and gum acacia matrices to create Cold Water Dispersible (CWD) powders and oil suspension beadlets that retain stability across pH ranges of 2.8 to 7.5.
Every single batch produced in our 12,447 m² industrial complex undergoes multi-wavelength High-Performance Liquid Chromatography (HPLC-DAD) to differentiate trans-isomers from degradation cis-isomers (including 9-cis and 13-cis artifacts), establishing uncompromising batch-to-batch homogeneity for exacting Swedish and Nordic formulators.

Regional Application Ecosystem: Västerås & Mälardalen Life Science
Situated strategically along the Lake Mälaren economic axis near Stockholm and Uppsala, Västerås serves as a premier industrial and advanced process engineering gateway. Our carotenoid extract solutions integrate directly into Sweden’s distinct high-tech manufacturing, clean-label dairy, aquaculture, and dermal longevity sectors.
Nordic Climate Dermal Defense
Formulated into nutricosmetic capsules and topical serums designed to counteract the extreme lipid barrier erosion caused by sub-zero Nordic winters, indoor dry heating, and low-angle UV exposure across Scandinavia.
Clean-Label Functional Dairy & Oat
Direct replacement for synthetic azo-dyes and tartrazine in Swedish dairy, oat beverages, and plant yogurts, delivering homogenous, acid-stable beta-carotene hues (E160a) without sedimenting or ring formation.
Ophthalmic Blue-Light Formulations
In high-tech hubs like Västerås where software and electrical engineering drives the workforce, lutein and zeaxanthin (5:1 macular ratio) are deployed into softgels to buffer high-energy artificial blue light.
Sustainable Salmonid Nutrition
Natural microalgae-derived astaxanthin (from Haematococcus pluvialis) calibrated for sustainable Baltic and North Sea aquaculture feeds, elevating flesh pigmentation and antioxidant protection without synthetic chemicals.
Endurance Sports Mitochondria Support
Cross-country skiing and winter athletics demand rapid lactic acid buffering. Astaxanthin’s protection of mitochondrial inner membranes enables athletic brands in Sweden to formulate high-performance sports recovery blends.
Ready-To-Drink Functional Beverages
Our microencapsulated CWD carotenoid powders dissolve instantly in cold water without turbidity or phase-separation, perfectly matching automated high-speed canning operations across Swedish contract packagers.
Regulatory Rigor & Clean-Label Transformation in Sweden
The dietary supplement and functional food market across Sweden, governed strictly by the Swedish Food Agency (Livsmedelsverket) and the European Food Safety Authority (EFSA), is witnessing an irreversible migration away from petrochemical colorants toward certified non-GMO, naturally fermented or botanically derived carotenoids.
Under the overarching EU Green Deal and the Farm-to-Fork initiative, Nordic brand owners face intense consumer scrutiny concerning solvent residues (Regulation EC No 396/2005) and microbiological safety. Traditional synthetic beta-carotene synthesized from petroleum derivatives is increasingly replaced by fermentation-based carotenoids produced by Blakeslea trispora or algae-sourced matrices.
Furthermore, the rapid rise of Nordic "Beauty-from-Within" brands has catalyzed severe demand for multi-active nutricosmetics. Rather than standalone pigments, the prevailing formulation trend pairs microencapsulated astaxanthin with bioactive marine collagen peptides, vitamin C from acerola, and plant polyphenols to trigger synergistic collagen-fibril synthesis and photoprotection.

Frequently Asked Questions: Sourcing for Västerås & Sweden
Detailed answers addressing European regulatory criteria, analytical validation methods, logistics to Västmanland County, and customized OEM processing parameters.
What are typical freight times and Incoterms for delivery to Västerås?
We provide full DDP (Delivered Duty Paid), CIF, or DAP shipping options direct to production facilities or warehouses in Västerås. Air cargo shipments routed via Stockholm Arlanda Airport (ARN) typically clear customs and arrive within 5 to 7 business days. For containerized bulk lots (25 kg drums to multi-pallet volumes), ocean transport via Gothenburg or Stockholm Port averages 28 to 35 transit days, complete with temperature monitoring data loggers.
Are your carotenoid extracts compliant with EFSA Novel Food regulations?
Yes. Our natural beta-carotene from Blakeslea trispora is fully authorized under EU Commission Regulation No 231/2012 (food additive E160a(iii)). Our microalgae astaxanthin oleoresin from Haematococcus pluvialis adheres strictly to Novel Food Regulation (EU) 2017/2470 specifying safe intake thresholds up to 8 mg astaxanthin per day for adult food supplement formulations.
How do you validate trans- vs. cis- isomer purity in your laboratory?
Standard UV/Vis spectrophotometry often fails to differentiate active all-trans carotenoids from biologically inactive cis-isomers. We utilize specialized YMC C30 reversed-phase liquid chromatography columns on our HPLC-DAD systems. This method resolves all-trans, 9-cis, and 13-cis isomers with baseline chromatographic separation, ensuring every batch meets declared potency values.
What is the Minimum Order Quantity (MOQ) for pilot trials and custom specs?
For standard catalog powders including natural beta-carotene, lutein, and astaxanthin beadlets, our pilot-run MOQ begins at just 1 kg to facilitate laboratory bench-testing and trial scale formulation. For customized beadlet carrier formulations, private-label capsule manufacturing, or specialized particle size milling (<200 mesh), project MOQs start at 25 kg or 50,000 finished capsules.
How is stability maintained during cold winter distribution across Scandinavia?
Carotenoids in pure crystalline form can undergo crystallization failure or micro-fracturing under temperature cycling. Our Cold Water Dispersible (CWD) and double-microencapsulated beadlets incorporate natural tocopherols (Vitamin E) and sodium ascorbate into the wall material, providing a hermetic oxygen barrier that maintains 98%+ active retention over 24 months even under sub-zero storage.
What compliance documentation accompanies each commercial shipment?
Every lot dispatched to European destinations includes a comprehensive batch Certificate of Analysis (COA) specifying HPLC assay, moisture, tap density, residual solvents (via GC), heavy metals (via AAS), and full microbiology (Total Plate Count, Yeast/Mold, E. coli, Salmonella). Furthermore, we supply complete Technical Dossiers containing Allergen Declarations, Non-GMO statements, BSE/TSE-free certificates, and SDS sheets.
