Description
Mingkai Bai and colleagues used a deep eutectic solvent to extract collagen peptides from sturgeon skin in a 2026 study. Sturgeon skin is a fish processing by-product rich in protein and collagen. Controlling peptide size matters because size shapes how products can be used.
They tested three solvents built on choline, and the oxalic acid version worked best, giving smaller peptides than the others. At tuned heat and mixing ratios, extraction reached near complete recovery of the available material. Longer treatment shifted output from mid sized peptides to very small ones, which shows size can be dialed in. A common alcohol recovered most peptides afterward. Computer simulation suggested how the solvent loosens the collagen helix. The authors call the route fast and potentially greener.
