Marine animal derived
Marine collagen peptide, fish skin
Gadus morhua and farmed Oreochromis niloticus — Hydrolyzed Collagen
The default Run below is Brittany, France, 4.83 kgCO2e/kg gross, Category C. Published values for this ingredient span 3.10 to 11.40 kgCO2e/kg, which is why a number without its production parameters is not worth forwarding.
Species record
- Species
- Gadus morhua and farmed Oreochromis niloticus
- INCI name
- Hydrolyzed Collagen
- Group
- Marine animal derived
- Harvest methods
- Processing co-product, fish skin. Enzymatic hydrolysis and spray drying
- Conservation status
- Species-dependent. Atlantic cod stocks are managed by quota and assessed per region.
- Typical uses
- Supplements, functional food, cosmetic ingestibles.
- Declared unit
- One kilogram of spray-dried hydrolysed marine collagen peptide.
- Typical gross range
- 3.10 to 11.40 kgCO2e/kg, Category C
- Default sourcing region
- Brittany, France, Route distance, Roscoff to Rotterdam gate
- Allocation decides this number. The default applies economic allocation to the skin, which is the common industry choice, and charges 6.4 kg of raw skin per kg of finished peptide.
- Limitation. Under mass allocation the figure is materially higher. The Report states both.
- No biogenic uptake is reported for an animal-derived ingredient.
