Product Description

Antarctic Krill Peptide is a high-value marine ingredient derived from the enzymatic hydrolysis of Antarctic krill protein. Characterized by its low molecular weight (≤ 1000 Da), it offers superior water solubility and rapid absorption rates compared to intact proteins. This peptide is rich in essential amino acids with an ideal ratio for human nutrition, closely matching FAO/WHO recommended patterns. It exhibits notable bioactive properties, including antioxidant, anti-fatigue, and immune-supporting effects. The production process often includes advanced deodorization and defluorination technologies to ensure purity, safety, and a neutral taste profile, making it a versatile and potent ingredient for modern health formulations.

Product Uses

This ingredient is widely utilized in the nutraceutical and functional food industries. Key applications include marine peptide supplements, sports nutrition products (such as recovery drinks and protein bars), and metabolic health formulations. It is also incorporated into cardiovascular support supplements, immune-boosting formulas, and anti-fatigue dietary supplements. Due to its high solubility and stability, it can be easily integrated into various delivery systems, including powders, capsules, tablets, and liquid beverages.

Formulation Recommendation

Recommended usage level: 1.0% – 5.0% in finished products, depending on the desired potency and application type. As a water-soluble powder, it should be dissolved in the aqueous phase during formulation. It is compatible with most common food ingredients, including vitamins, minerals, and other protein sources. For enhanced stability and targeted delivery, it can be encapsulated using polysaccharide-based systems (e.g., chitosan/alginate nanoparticles). Synergistic effects may be observed when combined with other antioxidants or marine-derived lipids.
