This article describes the study of the dispersion parameters, molecular weight and determination of the calcium content of collagen hydrolyzate obtained from the swim bladder of northern fish. The novelty of the work lies in the analysis of various research methods, as well as the introduction of new sources into scientific circulation. This article uses a wide range of collagen hydrolyzate research methods: freeze drying, infrared - spectroscopy, dynamic light scattering, viscometry, gel - penetrating chromatography and titrimetry. The use of all these methods makes it possible to evaluate and supplement the physicochemical properties of a collagen hydrolyzate obtained from the swim bladder of northern species of fish. The article may be interesting and useful for chemists.
