AI Technical Summary
Existing technologies lack gentle extraction methods to convert waste casings, a byproduct of the food industry, into active proteins, and fail to effectively remove endotoxins. This results in high costs, complex processes, and limited application forms for collagen-based biomaterials, making it difficult to meet the safety requirements of biomedical materials.
Collagen from edible animal casings is extracted using a mild enzymatic or acidic method. Endotoxins are removed by rinsing with surfactants and incubating with sucrose. Collagen fibers that can self-assemble under physiological conditions are then prepared and formed into a rapidly resolvable lyophilized powder for use in three-dimensional cell culture, surgical sutures, and tissue engineering scaffolds.
This technology enables the low-cost and efficient transformation of waste casings into multifunctional biomaterials that meet the performance and form requirements of different tissue engineering applications. It avoids the problems of high-temperature degradation and endotoxin residues associated with traditional methods, and provides flexible application forms and high-value-added products.
