Preparation and application of cowhide composite extract

The invention relates to the technical field of cowhide resource utilization, in particular to preparation and application of a cowhide composite extract. The preparation of the cowhide composite extract comprises the steps of degreasing and deodorization, cowhide slurry preparation, modified solution preparation, extraction and separation; a collagen solution in the extraction process and a collagen solution after extraction are correspondingly treated by adopting the modified solution and genipin, and the mechanical properties, thermal stability and biocompatibility of collagen substances inthe cowhide composite extract are effectively improved. The invention further provides application of the cowhide composite extract to the preparation of facial masks. The cowhide composite extract is mixed with microcrystalline cellulose and a plant extract to prepare the facial masks; the prepared facial masks can quickly penetrate into the skin deeply, nutrition is provided, the dermal cell structure is more compact,
