Industrial gelatin is a protein that is hydrolyzed from the collagen portion of the connective or epidermal tissue of animals. It has many excellent physical and chemical properties, such as the formation of reversible gel, bonding, surface activity, etc., in the food industry is widely used as jelly, emulsifier, stabilizer, binder and clarifying agent and other industrial gelatin, a fine chemical, is a gelatin product divided according to the different uses of gelatin. In daily life, people divide gelatin into edible gelatin, medicinal gelatin, photographic gelatin, and industrial gelatin. For industrial gelatin, it is divided into skin glue, bone glue, hot sol powder, protein special glue, feed special glue, match special glue. Let's wait.

Industrial gelatin, is a light yellow or brown particles, no unpleasant odor, no visible impurities. Its molecular weight is 1-100,000, containing 18 kinds of amino acids, water and inorganic salt content of less than 16%, protein content of more than 82%, is an ideal protein source.

In April 2012, the Internet spread that there was industrial gelatin made of broken leather shoes in old yogurt and jelly, and even industrial gelatin in medical capsules, and a number of companies were punished.

First, it is used in the match manufacturing industry, mainly using the foaming property of colloids to form pores, combined with oxidants, fire agents and fillers, so that it instantly ignites. The second is as a bonding agent, using its high strength, elasticity and toughness, to produce emery cloth, sandpaper, adhesive wood, binding books and used in gift box assembly line, senior Musical Instruments, furniture industry. The third is electrolysis, which is added to the electrolyte to help generate smooth and dense anode precipitation and eliminate production losses. The fourth is used for textiles, which can form a film on the yarn bundle to increase the toughness, strength, smoothness and elasticity of the fiber and prevent breakage. Fifth, it is combined with bichromate to produce negative photosensitive corrosion resistant film. The sixth is to extract hydrolyzed protein and use it in additives.

In short, industrial gelatin is widely used in board, furniture, matches, feed, packaging, papermaking, textile, silk, printing and dyeing, printing, ceramics, petroleum, daily chemical, coating, metallurgy and other industries of various products, and in which the main thickening, stability, cohesion, blending, glazing, sizing, bonding, water fixing and other roles.
