Featured Marine & Plant Proteins
Direct from production lines to worldwide supply networks. High-purity, sustainably sourced proteins optimized for global food, bakery, and sports nutrition manufacturing.
Microalgae Cultivation & Protein Extraction in the Pacific Atolls
As global food chains seek sustainable, climate-resilient proteins, the Republic of Kiribati is emerging as a focal point for blue economy innovation. Spanning 3.5 million square kilometers of the central Pacific Ocean, Kiribati offers pristine marine environments untouched by heavy industrial runoff. This clean environment is vital for cultivating premium microalgae proteins, including Spirulina (Arthrospira platensis) and Chlorella.
The combination of intense, year-round equatorial sunlight and clean marine resources provides a natural advantage. Sunlight drives high phototrophic growth rates, leading to efficient CO2 fixation and nutrient conversion. Developing algae protein production in Kiribati utilizes these marine and solar assets, offering an alternative to terrestrial agriculture which often suffers from soil depletion and freshwater scarcity.
- Equatorial Solar Isolation: Over 3,000 hours of natural sunlight annually optimizes photosynthesis.
- Zero Terrestrial Runoff: No industrial agriculture pesticides or heavy metal pollution in local waters.
- Circular Blue Economy: Minimal freshwater footprints compared to soy or wheat proteins.
Global Sourcing Priorities
Commercial buyers from the EU, North America, and Asia Pacific require high-purity protein ingredients with complete traceability. For sports nutrition, dietary supplements, and plant-based foods, Algae Protein provides a balanced amino acid profile, high digestibility, and hypoallergenic properties.
Dongguan Tsrel Biology Co., Ltd. addresses these requirements by combining advanced processing facilities with reliable sourcing. By monitoring critical quality parameters from growth media to final packaging, we ensure consistent supply and high product purity.

Technical Roadmap: Downstream Isolation & Cultivation
How we refine raw microalgae biomass into functional protein isolates, ensuring high bioavailability and neutral sensory profiles.
Utilizing closed photobioreactors and clean open ponds monitored for pH, temperature, and nutrient concentration. Optical density measurements track growth stages to time harvesting at peak protein content.
Microalgae are harvested using continuous-flow centrifuges and membrane filtration systems. This step concentrates the biomass without chemical flocculants, maintaining the organic integrity of the product.
The microalgal cell wall is opened using high-pressure homogenization or food-grade enzymatic digestion. This process releases intracellular proteins, specifically phycobiliproteins and cytoplasmic isolates, into solution.
Proteins are separated from insoluble carbohydrates and lipids via isoelectric precipitation. The isolated fraction is spray-dried at low temperatures, resulting in a fine, dispersible powder with high emulsifying and foaming properties.

Frequently Asked Questions
Addressing critical points on certification, applications, supply chain stability, and quality control.
What certifications do your algae and vegetal protein products hold?
Our products are processed in certified facilities meeting ISO 9001, HACCP, GMP, Kosher, and Halal standards. We also offer organic-certified batches (USDA NOP & EU Organic) backed by third-party testing for export markets.
How does the shipping and supply chain work from Kiribati and China?
We combine our raw material cultivation networks in clean Pacific regions with our processing and export facilities in China. This structure allows us to offer both bulk raw ingredients and finished, high-purity protein formulations. Finished products are shipped worldwide via established sea and air freight networks.
What is the digestibility and amino acid profile of your algae protein?
Our microalgae proteins contain all nine essential amino acids, with a PDCAAS (Protein Digestibility-Corrected Amino Acid Score) comparable to whey and soy. Disruption of the cell walls ensures digestibilities exceeding 85% for human formulations.
Do you support OEM / ODM formulations?
Yes. Our R&D team creates customized protein powders, enzyme additions, and nutrient ratios tailored to specific target markets, functional requirements, or flavor profiles.
