明胶制作方法及工艺流程（Method and process for making gelatin） Method and process for making gelatin Gelatin process Gelatin is an animal skin, bone, white connective tissue contains collagen, purified and primary hydrolysis after processing of a product. Gelatin is light yellow to yellow, translucent, micro crystalline powder or flake, no special odor, no volatility. In general, gelatin contains less than 16% water. In dry environment, gelatin is relatively stable and easy to absorb moisture in the humid environment. It is decomposed and decomposed by bacteria. The gelatin becomes soft when it burns and expands until it is carbonized. It gives off a special angle to burn feathers or ammonia. Gelatin in cold water insoluble, but can absorb water and soft, and easily dissolved in hot water. Gelatin is difficult to dissolve in gasoline, ethanol, chloroform and other common organic solvents. But soluble in acetic acid, salicylic acid and benzene, two formic acid and other organic acids, but also soluble in urea, thiourea and potassium bromide, potassium iodide and other aqueous solutions. Gelatin is a kind of high molecular compound, its molecular weight is about Use of gelatin: They can be divided into photographic gelatin, edible gelatin and industrial gelatin according to their uses. It is widely used in food, medicine, chemical industry, textile, printing and dyeing, paper making, matches, hardware, furniture and sensitive materials. 1, the food industry: for mom, sugar, snacks, canned, ice cream, soda, Boudin and so on. 2 、 pharmaceutical industry: used for surgical dressings, modulation pills, ointment, capsule, pharmaceutical pills coating, cod liver oil pill skin. 3, the photosensitive material is used in the manufacturing of photographic film, X, film, printing paper, light amplification paper etc.. 4, the printing industry for photoengraving and high printing etc.. 5, the textile industry for silk, cotton, blanket, paper, leather products, textile products a
