Summary:The invention discloses a method for producing ox collagen by means of tail-end gelatin of oxhide gelatin, and belongs to the field of oxhide processing. According to the method, through steps of ethyl alcohol pre-treatment, enzymolysis, enzyme removal and the like, the collagen is extracted, through ethyl alcohol, pre-treatment can be conducted on the tail-end gelatin easily, impurities in the tail-end gelatin are removed, the purity and the quality of the collagen are improved, enzymolysis time is shortened, by adjusting an enzymolysis sequence, the molecular weight of the collagen is controlled, collagen products with molecular weight between 3 KDa to 8 KDa can be prepared, and the molecular weight of the prepared collagen is centralized, and can account for more than 70% of total molecular weight of collagen; a whole preparation process can be completed in 15-20 h, so that compared with the prior art, the method for producing the ox collagen by means of the tail-end gelatin of theoxhide gelatin has the ad
