Gelatin (also Gelatine) is a protein product, manufactured by partial hydrolysis of collagen found in bones, hooves, connective tissues, and skin of animals.
When added to recipes it produces a gel. A similar product known as agar can be obtained from vegatable sources. Common examples of foods which contain gelatine are trifle, jelly, jam and aspic.
Gelatine is also used for pharmaceutical capsules.
R is amino acid polypeptide macromolecule. It is granular matter made of fresh cattle skin and pig skin. We can extract hydrolysis macromolecule animal protein from it, the purity is 98%. It has 18 kinds of amino acids too.
According to material, production method and quality, the gelatin products include edible gelatin, medicinal gelatin, Industrial gelatin, bone glue and photo gelatin, the low viscosity and low ash industrial gelatin for extraction of hydrolysis macromolecule animal protein, and the industrial gelatin for feedstuff additives.
Gelatin is a half transparent granule and power without any taste and odor. Its color is white or light yellow. Its MW is 10,000-70, 000, the high grade gelatin may be 100,000-150,000. The gelatin has low methionine and high glycin, proline and hydroxyproline.
Gelatin is hard to be dissolved in water, but it can absorb 5 -10 times water of its weight. It can be dissolved in warm water. It can form the gel after frozen. The MP is 24-28 centi degree. Its solubility is similar with freeze temperature. Affected by moisture, temperature and humidity, the gelatin may go bad easily.
Uses: gelatinizer, stabilizer, thickener, foamer, swelling agent
Application:meat, ice cream, frozen meat, salad, pudding, frosting, yolk juice, beer clarifier, cheese and dairy, sausage, cracker, cold drink, soft adhesive powder
Pharmaceutical gelatin is used for capsule, sugar coating, germ cultivation.
Used in photosensitive roll film.
Industrial gelatin is used in plating liquid, match, emery cloth, emerypaper, wood adhesion, book adhesion, dial and silk screen agent, it is also applied in dyeing, petroleum, leather, the extraction of hydrolyzed protein and beverage additives.
