The ingredient: target specification
Quick answer
We are developing a marine collagen ingredient from the skeleton of wild-caught North Atlantic cod, in two formats: hydrolysed collagen peptides and native (undenatured) Type II. The figures below are development targets, not a certificate of analysis.
Updated
Two formats from one skeleton
Fish skeleton contains bone, which is rich in Type I collagen, and cartilage, which contains Type II. We use the same raw material for two ingredients with different doses and uses.
| Format | What it is | Typical use | Status |
|---|---|---|---|
| Hydrolysed collagen peptides | Collagen cut by enzymes into short peptides, target 0.5 to 2 kDa | Gram-dose formats: powders, sticks, drinks, gummies | Lab trials, pilot mid 2027 |
| Native Type II powder | Type II collagen kept in its natural, undenatured form by a low-temperature process | Milligram-dose formats: capsules, tablets | In development |
| Bone mineral fraction | Calcium and phosphorus recovered when the bone is demineralised | Mineral co-ingredient | In evaluation |
Target specification: hydrolysed peptides
| Raw material | Skeleton (backbones and frames) of wild-caught Atlantic cod, Gadus morhua |
|---|---|
| Catch area | Northwest Atlantic, FAO area 21, landed in Greenland |
| Production | Denmark |
| Collagen types | Type I and Type II, to be confirmed per batch by analysis |
| Protein | Over 90% (target) |
| Peptide size | 0.5 to 2 kDa (target) |
| Appearance | White powder (target) |
| Taste and odour | Neutral (target) |
| Solubility | Cold-water soluble, clear solution (target) |
| Animal source | Fish only, no bovine or porcine material |
| Allergen | Fish: EU and UK allergen labelling applies |
| Dietary fit | Pescatarian; halal and kosher certification planned |
| Documents for commercial lots | Specification, certificate of analysis per lot, microbiology and contaminant results (planned) |
Mineral fraction and collagen mineral blend
Demineralisation dissolves the bone mineral, which is mostly calcium and phosphorus. We plan to purify it as a separate sidestream fraction rather than discard it. It can be supplied three ways: collagen peptides alone, the mineral fraction alone, or a collagen mineral blend from one source. Separate ingredients leave you free to set your own ratio in the formulation.
The mineral fraction is in development. Its soluble form, purity and contaminant specification will be set in our pilot trials, and the regulatory route for fish bone minerals is being confirmed.
How it is made, in brief
- Cleaning and pre-treatment to remove fat and non-collagen protein.
- Demineralisation to free the collagen from the bone mineral, which is kept as its own fraction.
- Enzymatic hydrolysis to the target peptide size (peptides only).
- Purification and filtration for a neutral taste, odour and colour.
- Drying to a fine powder.
Process parameters are being set in lab trials in Denmark and will be fixed in pilot trials planned for mid 2027. They may change.
