Abstract: The present invention discloses a method of preparing procollagen from freshwater fish. The method comprises the following steps: pressure treatment, physical crushing, mixing and emulsification, homogenization, refrigeration, cleaning, extraction, homogenization, inactivation, homogenization, and filtration. In the mixing and emulsification step, freshwater fish tissue containing collagen is mixed with a surfactant to remove endotoxins to below 0.25 EU/ml. The procollagen is extracted following the step of adding enzymes and an acid solution of pH 3 to 6 to the pretreated tissue. The pretreatment of freshwater fish tissue in this invention can effectively reduce the endotoxins to below 0.25 EU/ml. The extraction technique of this invention can extract and retain greater amounts of procollagen while increasing its denaturation temperature and preserving the intact, tightly twisted triple-helix bonds of type I procollagen.
