Due to the continuous expansion of the demand for casings, the supply of natural casings is far from meeting the needs of the market, so collagen casings came into being. Collagen casings are casings made of collagen extracted from animal raw materials such as cow split hides. The source of raw materials is rich and stable, the cost is low, industrialized production, and the net profit rate of the industry has reached more than 40%. Its properties are very close to natural sausage casings, with edibility, good water vapor permeability, heat shrinkage and adhesion to meat stuffing. At the same time, the collagen casing is tasteless, safe, smokeable and colorable, the size of the casing is uniform, and the specification can be freely determined. It is suitable for making enema products that need to be smoked and dried, and has a very large market prospect.

 

The production technology of collagen casings originated from Johnson & Johnson, the founder of collagen casings in the United States. Its wet production technology is at the leading level in the world. This technology has been monopolized by the inventors for a long time. Now, Johnson & Johnson chooses us as his only partner in the world, and in March 2012, Beijing Qiushi Agricultural Development Co. Ltd. Nitta Gelatin Co., Ltd. The hotel signed the "Biological Protein Casing Project", and the company obtained the exclusive right to use the leading technology of collagen casings in the country through exclusive authorization, which created the situation that China's wet-laid casing products have changed from imports to exports.

 

         The implementation of this project has created a precedent for the bio-collagen casing industry of China's wet-process production technology, filled the domestic technology gap and product gap, can lead the casing industry to develop towards standardization, scale, and internationalization, and is conducive to the in-depth development of casing products , It is conducive to promoting the upgrading of casing industry, promoting the employment of migrant workers, helping farmers and herdsmen to become rich, increasing the scale of export earnings, and improving domestic and international market competitiveness.
