how are collagen peptides made？

At a high level, it’s a three-step journey: extraction, hydrolysis, and drying. We start with collagen-rich raw materials (like bovine hides or fish skin). First, we use a mild thermal treatment to extract the raw collagen, which essentially gives us gelatin.

The magic happens during enzymatic hydrolysis. Gelatin has huge molecular chains, which makes it gel up when cold. We introduce specific food-grade enzymes to precisely cut those long protein chains into tiny pieces—typically under 5,000 Daltons. Finally, the liquid is filtered, purified, and spray-dried into the free-flowing, cold-water-soluble powder you see on the market. It’s pure biochemistry at scale.
