The physicochemical properties of acid‐soluble collagen (ASC) from refiner discharge and the partially purified collagen (PPC) from both the refiner discharge and the fish skin were evaluated. Yield of collagen from refiner discharge was 34% higher in PPC than ASC. Mercury, lead, cadmium, and chromium contents of PPC from refiner discharge were not detected. There was no difference in the pattern of sodium dodecyl sulfate‐polyacrylamide gel electrophoresis (SDS‐PAGE) between ASC and PPC from refiner discharge. PPC from refiner discharge showed better functional properties than that from skin and was similar to ASC: whiteness, solubility, emulsifying activity, and cooking stability. Therefore, PPC from refiner discharge could be used as a new resource.
