Peptide collagen được sản xuất như thế nào?

To understand how it’s made, you have to look at where it starts. From a sourcing perspective, collagen peptides are entirely dependent on animal co-products. The major sources are bovine (cattle), porcine (pigs), marine (fish), and avian (chicken).

For B2B buyers, how it’s made matters less than what it’s made from. For instance, bovine collagen usually comes from the split leather industry, while marine collagen uses fish skins from processing plants. If you are exporting this stuff, your buyers will want to know the exact origin, whether it’s grass-fed certified, or if it carries Halal/Kosher status right from the slaughterhouse level.

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.
