Solidification method of edible collagen casing

The invention provides a curing method of an edible collagen casing, and relates to the technical field of collagen casing processing. Pigskin and animal tendons are mainly adopted as main materials of the edible collagen casing, the main materials are treated through boiling, alkali washing, enzymolysis, acid mixing and freeze-dried powder crushing, then propylene glycol alginate, pectin, xanthan gum, beta-cyclodextrin, glycerin and mannitol are added as auxiliary materials in an auxiliary mode to serve as auxiliary materials, and after mixing, extrusion and variable-temperature drying are conducted to obtain the casing. The invention overcomes the defects of the prior art, effectively ensures the thermal shrinkage of the collagen casing, enhances the tensile strength of the collagen casing, comprehensively enhances the cooking effect of the sausage filled with the casing, and enhances the quality of the whole casing. 本发明提供一种可食用胶原肠衣的固化方法，涉及胶原肠衣加工技术领域。所述可食用胶原肠衣主要采用猪皮和动物蹄筋为主料，通过煮制、碱洗、酶解、酸混后冻干粉碎来处理主料，后辅助添加藻酸丙二醇
