Process Description
Raw Material Preparation
Fresh Spirulina biomass or dried Spirulina powder is received, inspected, and prepared into a controlled slurry under hygienic conditions.
The preparation stage ensures:
- Uniform feed consistency
- Controlled pH
- Minimal oxidation
- Maximum protein preservation
Cell Disruption
Specialized mechanical cell disruption technology breaks the robust Spirulina cell walls, releasing intracellular proteins and valuable pigments.
Benefits include:
- High protein recovery
- Efficient phycocyanin release
- Reduced processing time
- Improved extraction efficiency
Aqueous Protein Extraction
The disrupted biomass undergoes controlled aqueous extraction using optimized pH and temperature conditions to preserve protein functionality and sensitive bioactive compounds.
Solid-Liquid Separation
The extracted slurry is clarified using decanters or centrifuges to efficiently separate insoluble biomass from the protein-rich liquid.
Membrane Filtration
Advanced ultrafiltration (UF) and microfiltration (MF) systems concentrate proteins while removing impurities and low-molecular-weight compounds.
Advantages include:
- Excellent protein purity
- Low-temperature processing
- Improved nutritional quality
- Reduced thermal degradation
Protein Concentration & Purification
The concentrated protein solution is further purified to achieve desired protein specifications for food and nutraceutical applications.
Optional downstream processing enables:
- Spirulina Protein Isolate
- Protein Concentrate
- Phycocyanin Fraction
- Chlorophyll Fraction
Drying
Depending on product requirements:
- Spray Drying for high-volume production
- Freeze Drying for premium bioactive retention
Both systems ensure:
- Excellent solubility
- Low moisture
- High shelf stability
- Superior product functionality
Quality Standardization
Finished products are analyzed for:
