Differences between collagen peptides and gelatin
Collagen is the most abundant protein in composition of animals’ bodies. Collagen is an insoluble protein found in the bodies, while gelatin is a soluble protein that is processed from that collagen. However, collagen peptides are a low-molecular-weight soluble protein obtained by hydrolyzing gelatin with enzymes and, unlike gelatin, collagen peptides solution does not harden even when dissolved in water and cooled.
Gelatin
- Soluble protein
- Reversible sol-gel conversion
Collagen peptides production
After pretreatment of raw materials, hot water extract of collagen is hydrolyzed through an enzymatic process to adjust to the desired molecular weight. After that, collagen peptides are purified and processed into powder form by filtering, ion exchange process, sterilizing and drying.
Nutritional facts of Nippi’s collagen peptides
Collagen peptides are mostly composed of protein (collagen) and have little ash and lipids.

The type of collagen contained in nippi peptide series
There are different types of collagen, depending on the animal species and organs, and 28 types are currently confirmed. The type of collagen contained in nippi peptide series is type I, which is the most abundant in the body (predominantly in skin, bones, tendons, fish scales, and most connective tissue).
