Product Description

Antarctic Krill Powder is a natural marine ingredient produced from Antarctic krill (Euphausia superba) following krill oil extraction, processed through a drying technology. This defatted krill meal retains the valuable nutritional profile of krill while offering a concentrated source of marine protein, phospholipid-bound omega-3 fatty acids, and natural antioxidants.

The powder presents a distinctive brick-red to reddish-brown color with a characteristic seafood aroma, reflecting its natural astaxanthin content and marine origin. It is a free-flowing, easy-to-handle ingredient suitable for inclusion in aquatic feed and pet food formulations.

Quick Details

Key Nutritional Components

Marine Protein — Antarctic krill powder provides a highly digestible protein source with a well-balanced amino acid profile reflecting the requirements of aquatic species. A large proportion of the protein consists of short peptides, enhancing bioavailability.
 

Phospholipid-Bound Omega-3 Fatty Acids — The lipids in krill meal are characterized by a high phospholipid content (approximately 40%–45%). Omega-3 fatty acids (EPA and DHA) in phospholipid form demonstrate superior bioavailability compared to triglyceride-bound omega-3 from fish oil, with studies showing up to 42% greater effectiveness in raising omega-3 index levels.
 

Natural Astaxanthin — Krill powder contains naturally occurring astaxanthin, a powerful antioxidant carotenoid that provides the distinctive red-orange pigmentation and contributes to product stability by protecting vulnerable fatty acids from oxidation.
 

Additional Nutrients — The ingredient also contains choline (in phosphatidylcholine form), beta-carotene, trace minerals, and naturally occurring feed attractants including trimethylamine oxide (TMAO), free amino acids, and nucleotides.

The Main Application for Antarctic Krill Powder in Bulk?

1. Aquaculture Feed

Antarctic krill powder is widely used in aquatic feed formulations as a functional ingredient that enhances both palatability and nutritional value:
1) Feed Attractant — Natural compounds including TMAO, free amino acids, and nucleotides stimulate feeding behavior and improve feed uptake, particularly in diets where fish meal has been partially replaced with plant proteins.
2) Growth Performance — Research demonstrates that krill meal inclusion in salmon diets significantly increases weight gain, specific growth rate (SGR), and protein efficiency ratio (PER).
3) Stress Resistance — Krill meal supports improved survival and stress tolerance in fish and shrimp under challenging conditions such as salinity changes or temperature fluctuations.
4) Fillet Quality — Inclusion in functional feeds supports improved fillet quality and overall fish health.

Recommended Inclusion Levels:
Shrimp feed: 2%–5%
Fish feed: 3%–10% (depending on species and formulation targets)

2. Pet Food
Krill powder is a premium ingredient for functional pet food and supplement formulations, valued for its nutrient density and palatability:
1) Omega-3 Source — The phospholipid-bound EPA and DHA in krill are more bioavailable than fish oil omega-3, supporting cognition, mobility, healthy aging, and immune function in cats and dogs.
2) Skin and Coat Health — Natural astaxanthin and omega-3 fatty acids support healthy skin condition and coat shine.
3) Palatability — The natural seafood aroma and flavor make krill powder highly palatable for pets, useful in both meal formulations and supplement applications.

Recommended Inclusion Levels:
Pet food: 1%–5% (dry matter basis)
Supplements: 0.1–2.5 g per day for a 20 kg dog
