Freeze-Dried Krill Superba for Bulk Buyers
Freeze-dried Antarctic krill (Euphausia superba) is used in ornamental fish diets primarily as a high-protein marine ingredient, natural carotenoid source and feeding stimulant. For bulk procurement, the relevant specifications are not simply krill species and appearance - buyers should verify crude protein, moisture, crude fat, ash, particle size, astaxanthin content or assay method, microbiological limits, water activity, packaging barrier performance and batch traceability.
For commercial aquarium operations and fish-food manufacturers, a practical purchasing specification is typically built around crude protein ≥60% on a declared analytical basis, low residual moisture, controlled particle size and packaging capable of limiting moisture uptake during storage. For a broader ornamental-feed portfolio, see freeze dried fish food supplier.
Protein ≥60%
Controlled Moisture
Particle Sizing
OEM Packaging
🔹 Crude Protein
Target ≥60% with analytical basis clearly stated on COA.
🔹 Moisture & Water Activity
Low residual moisture supported by aw measurement and barrier packaging.
🔹 Astaxanthin
Concentration and validated analytical method when color positioning is required.
🔹 Batch Traceability
Lot No. → raw material → processing batch → QC results → packaging batch → shipment.
Nutritional Profile & QC Specifications
Freeze-dried krill is hygroscopic - packaging is part of the ingredient specification, not just a branding decision.
Crude Protein ≥60%
Analytical basis must be stated on COA as-is vs. dry matter changes supplier comparison.
Moisture + Water Activity
A moisture percentage alone does not fully describe shelf stability. Assess aw, oxygen exposure and barrier packaging together.
Lipid & Oxidation Control
Peroxide value, anisidine value where applicable, sensory odor assessment and oxygen-barrier packaging.
Microbiology & Heavy Metals
Total plate count, yeast/mold, Salmonella, E. coli and heavy metals according to destination-market requirements.
Applications in Color Enhancement
Arowana, cichlids and koi are the primary ornamental groups where freeze-dried krill is used as a marine protein and natural carotenoid source. Large Arowana can take whole or coarse pieces, adult cichlids and koi perform well on medium-sized particles, and juvenile ornamental fish require a finer milled fraction. For fish-food brands, krill may also be incorporated as a controlled powder or granule in blended dry diets, where consistent milled fractions prevent segregation during mixing. Distributor repacking and OEM private-label programs should define particle-size distribution, net weight tolerance and moisture-barrier packaging before production. Across all applications, krill should be evaluated as one component of a pigmentation-oriented feeding program, not as a standalone color enhancer--pigment deposition also depends on species, genetics, dietary carotenoid concentration, digestibility, feeding duration, fish size, water quality and overall protein and lipid supply.

What to Audit Before Bulk Purchase
Freeze-Dried Euphausia superba should be purchased as a controlled marine ingredient, not simply as a dried crustacean product.
🔹 1. Raw-Material Identification
Supplier must identify biological source as Euphausia superba when Antarctic Krill Superba is specified. Declaration must be consistent across specification, invoice, COA, label and batch documentation.
🔹 2. Moisture & Water Activity
For long-distance distribution, assess moisture + aw + oxygen exposure + packaging barrier + storage temperature together - not moisture alone.
🔹 3. Microbiological Control
Total aerobic microbial count, yeast and mold, Salmonella, E. coli and other organisms specified by the buyer or destination regulations.
🔹 4. Oxidation Control
Peroxide value, anisidine value where applicable, sensory odor assessment and packaging oxygen-barrier specification. Acceptance limits agreed between buyer and supplier. For commercial quantities, see wholesale freeze dried krill superba.
