Bulk Spirulina Powder | High-Protein & Phycocyanin Algae Base
Premium Plant-Based Superfood Matrix by Xi'an Tihealth
In the rapidly expanding plant-based nutrition and clean-label supplement sectors, formulators require microalgae ingredients that deliver high protein density without the risks of heavy metal contamination. Xi'an Tihealth provides an industrial-grade, ultra-pure Spirulina Powder (Arthrospira platensis) engineered from fully integrated, closed-loop cultivation systems.
Cultivated in pristine, unpolluted water sources and processed via an advanced low-temperature (≤40°C) spray-drying protocol, our Spirulina powder guarantees maximum preservation of its heat-sensitive bioactives. Standardized to deliver an exceptional ≥64.0% protein content (dry basis) and enriched with ≥13.0% Phycocyanin (C-PC), this 80-mesh ultra-fine dark green powder is the gold standard for fortifying vegan protein blends, functional smoothies, and clinical-grade super-green capsules. With heavy metal and microbial limits strictly exceeding EU/US import standards, it offers uncompromising safety and bio-availability.
1. Formulation Edge: Why Choose Our Cultivated Spirulina?
For R&D food technologists, sourcing microalgae often involves battling high microbial counts, fishy off-odors, and toxic heavy metal accumulation. Our integrated manufacturing eliminates these industrial bottlenecks:
- Low-Temperature Active Retention (≤40°C):
- Standard drum-drying (commonly 60-80°C) permanently degrades Phycocyanin and oxidizes essential fatty acids (GLA). Our cold spray-drying protocol ensures a nutrient loss rate of <5%, yielding a vivid dark-green powder with a remarkably mild, fresh-algae aroma rather than a pungent "fishy" smell.
- Ultra-Fine Dispersion (100% pass 80-Mesh):
- Generic Spirulina often leaves gritty residues and clumps in aqueous solutions. We employ cryogenic micronization to achieve an ultra-fine particle size (≤180 μm). This ensures rapid, homogeneous dispersion in cold liquids and flawless compressibility for tablet manufacturing.
- Full-Link Purity Control (Seed to Powder):
- Microalgae absorb heavy metals like a sponge. By completely isolating our cultivation ponds and utilizing triple-filtered water, our Lead (Pb) and Arsenic (As) levels test at less than half of strict national thresholds, guaranteeing pediatric and clinical-grade safety.

3. Primary Functional Mechanisms (R&D Perspective)
Replacing generic "superfood" claims with scientifically validated biological mechanisms, Spirulina acts as the core active ingredient in formulas targeting:
Vegan Protein & Amino Acid Synthesis
Spirulina is a complete protein source, containing all 9 essential amino acids in highly bioavailable proportions. Notably rich in Isoleucine, Leucine, and Valine (BCAAs), it provides the foundational building blocks required for muscle protein synthesis, making it indispensable for vegan sports nutrition and post-workout recovery blends.
Cellular Antioxidant Defense (Phycocyanin)
The intense blue-green pigment of Spirulina is driven by Phycocyanin (C-PC), an exceptionally potent free-radical scavenger. Clinical nutrition studies highlight Phycocyanin's ability to inhibit pro-inflammatory enzymes (such as COX-2) and protect cellular DNA and lipid membranes from environmental oxidative stress and radiation damage.
4. Targeted B2B Applications
- Dietary Supplements (Tablets & Capsules): The core raw material for standalone "Super Green" tablets. Our 80-mesh powder ensures excellent flowability and direct compressibility without requiring excessive binders.
- Functional Food & Beverages: Utilized in plant-based protein shakes, energy bars, and green smoothies to radically boost protein and vitamin B/K content while imparting a natural, vibrant green hue.
- Natural Food Colorant: Acts as a stable, clean-label carrier for extracting pure Phycocyanin, widely used to impart natural blue/green coloring to ice creams, candies, and premium dairy products.
- High-End Aquaculture Feed: A premium, highly digestible additive for aquaculture (shrimp/fish), utilized to replace synthetic fish meal, enhance survival rates, and naturally improve pigmentation.
5. Closed-Loop Cultivation & OEM Services
Xi'an Tihealth oversees the entire lifecycle of our Spirulina, guaranteeing absolute traceability from algae seed to final powder:
- Strain Cultivation & Harvesting:
- Premium Spirulina strains are grown in strictly monitored, high-alkaline raceway ponds. The mature algae slurry is harvested and subjected to centrifugal dehydration to remove excess water.
- Multi-Stage Purification:
- The biomass undergoes rigorous washing and filtration to strip away any environmental impurities or competing microorganisms.
- Cryo-Spray Drying & Milling:
- The pure slurry is instantly dried at low temperatures (≤40°C) to lock in the protein matrix. It is then ultra-finely milled (80-mesh) and passed through high-sensitivity metal detectors.
Contract Manufacturing (OEM/ODM) Capabilities
We provide full-service formulation for brands looking to launch finished Spirulina products. Our GMP-certified facility supports:
- Custom Dosage Forms: Direct compression into 500mg/1000mg tablets, encapsulation, or custom-blended powder sachets.
- Formulation Adjustments: Synergistic blending with Chlorella, Wheatgrass, or targeted extracts to boost specific polysaccharide/triterpenoid profiles.
- Compliance Support: Full documentation (COA, MSDS) provided, ensuring compliance with FDA, EU, and TGA regulations for swift market entry.
6. Secure Packaging & Global Logistics

7. Formulation & Technical FAQ
This is a strictly Food-Grade raw material. It is cultivated and processed in compliance with human consumption standards (GB/T 29659), holding an SC production license. While it can be utilized in high-end aquaculture, its primary applications are premium health supplements, nutritional drinks, and functional food additives.
2：Why is low-temperature spray drying (≤40°C) so important?
Spirulina contains highly heat-sensitive bioactives, most notably Phycocyanin and various vitamins. Standard industry drying at 60-80°C permanently denatures these proteins. Our ≤40°C protocol maximizes the retention of Phycocyanin (≥13%) with a nutrient loss rate of less than 5%, yielding a vastly superior nutritional profile and a fresher taste.
3：Does the 80-mesh powder clump in liquids?
No. Our 80-mesh ultra-fine milling (particle size ≤ 180 μm) ensures that the powder disperses rapidly in cold water without forming cohesive lumps. This fine granulation is critical for downstream efficiency, making it incredibly easy to process into direct-compression tablets, hard capsules, or seamless additions to RTD beverages.
4：What are the storage requirements to maintain potency?
Spirulina should be stored in a cool, dry environment, strictly away from direct UV light to prevent chlorophyll degradation. Our bulk packaging utilizes nitrogen-flushed aluminum foil bags or lined cardboard drums to prevent moisture ingress and oxidation. When stored properly, it maintains a stable shelf life of 24 months.
