| Source declaration |
Confirms the organism, production system, and source traceability. |
Spirulina or Arthrospira source, country of origin, cultivation method, and supplier declaration. |
| Phycocyanin level |
Important for blue-green pigment value and product differentiation. |
Phycocyanin percentage or marker data, test method, and COA result where available. |
| Chlorophyll and carotenoid profile |
Relevant to natural color contribution and formulation strategy. |
Chlorophyll, total carotenoids, beta-carotene, zeaxanthin, or pigment profile where available. |
| Protein level |
Spirulina is often evaluated as both pigment and protein-rich algae ingredient. |
Crude protein, amino acid profile, nitrogen method, and batch COA confirmation. |
| Color intensity |
Visual consistency affects premix appearance, finished feed color, and product positioning. |
Color description, color value, photo standard, or batch comparison data where available. |
| Particle size |
Affects blend uniformity, dusting, dosing, suspension, and finished feed appearance. |
Sieve analysis, particle size distribution, bulk density, and flowability data. |
| Moisture and water activity |
High moisture can affect caking, microbial quality, pigment stability, and shelf-life. |
Moisture limit, water activity where available, drying method, and storage conditions. |
| Microbiological quality |
Critical for feed safety, pet food, aquafeed, export markets, and customer approval. |
Total plate count, yeast and mold, Salmonella, E. coli, coliforms, and other requested parameters. |
| Heavy metals |
Algae products may require close review for environmental contaminants. |
Lead, arsenic, cadmium, mercury, and any buyer-specific heavy metal limits. |
| Microcystin and cyanotoxin controls |
Important for blue-green algae products and customer safety programs. |
Microcystin testing, cyanotoxin statement, cultivation control, and batch safety documentation. |
| Pesticides and contaminants |
Needed for import approval, customer audits, and sensitive formulations. |
Pesticide residue statement, PAH, dioxin, PCB, mycotoxin, and other contaminant data when required. |
| Regulatory suitability |
Permitted use, label wording, species claims, and organic or natural positioning vary by market. |
Feed-grade declaration, origin documents, registration support, and destination-market compliance documents. |
| Packaging |
Impacts moisture protection, pigment retention, odor control, and export logistics. |
Bag size, liner type, nitrogen flushing if available, carton or drum option, pallet configuration, and container loading details. |
