Krill peptide features excellent water solubility, acid and alkali resistance, and heat stability. It maintains stable physicochemical properties under simulated gastrointestinal environments, making it suitable for the development of various food dosage forms:

Solid beverages: Boasting good solubility, it can be used alone or compounded with other peptides, vitamins and minerals to formulate solid beverages. The industry recommended dosage is 3–5 g/day, subject to adjustment based on product positioning and national regulatory requirements.

Hard capsule formulations: The peptide powder has favorable flow properties, suitable for hard capsule filling. It is ideal for premium dietary supplements and can also be combined with krill oil softgels to create a “peptide + oil” bundle package.

Oral liquids: It exhibits strong stability in aqueous solutions for oral liquid development. It can be formulated with fruit juice and honey to modify flavor and mask inherent seafood taste.

Functional gummies and baked foods: Its heat resistance fits the processing of gummies, energy bars, biscuits and other products. Containing astaxanthin, the finished products show a light red hue, which is the natural color of the raw material.

Raw material for special dietary foods: With balanced amino acids and high digestibility, it can serve as a protein ingredient for sports nutrition foods, elderly nutritional foods and other special dietary foods.
