What happens to the collagen?
Hydrolyzed means the manufacturer has cut the long protein chains in collagen into shorter pieces. A protein chain consists of amino acids joined end to end. Hydrolysis breaks some of the bonds between them, leaving shorter chains called peptides.
You may see three names for this ingredient. “Hydrolyzed collagen” describes what happened to the protein. “Collagen peptides” names the resulting pieces. “Collagen hydrolysate” is another name for the mixture. Manufacturers can use different enzymes and processing conditions, so two powders with the same ingredient name can contain different mixes of chain lengths.
Would it set a panna cotta?
Use the gelatin your recipe calls for. Gelatin also comes from collagen, but its chains are long enough to form a network that holds liquid as it cools. That network gives panna cotta its wobble. Plain collagen peptides have much shorter chains. Swap them for the gelatin and the cream will stay pourable.
Gelatine Manufacturers of Europe uses this difference in a lab test. After warming a sample in water and chilling it for six hours, the tester turns the tube upside down. The collagen peptide mixture flows out immediately. The gelatin holds together.
Where do the source and amount appear?
The ingredient line on a Sports Research unflavored powder reads “Hydrolyzed Bovine Collagen Peptides.” Bovine tells you the collagen came from cattle. The Supplement Facts panel supplies a separate detail, 11 g of those peptides per serving.
California Gold Nutrition also uses the word hydrolyzed on its marine powder. Its 200 g label lists 5 g of collagen peptides per serving and identifies fish in the allergen statement, specifically barramundi, red snapper or both. If you need to identify an allergen, read the ingredient and allergen wording on your own container.
Frequently asked questions
Does hydrolyzed mean the powder is all individual amino acids?
The powder contains peptides, each made of amino acids that are still joined together. A list of amino acids on the package can describe the building blocks of those chains.
Does the word hydrolyzed tell me what it will do for my skin?
It tells you how the ingredient was made. To evaluate a skin claim, look for human research that identifies the peptide mixture, the amount people took and the skin change researchers actually measured.
