Gelatine Powder Usage and Synthesis.

1.Edible gelatin. It is an important ingredient and additive in the food industry, often used as gelling agent, stabilizer, emulsifier, thickener and clarifier in the production of meat products, cakes, ice cream, beer, fruit juice and so on.

2. Biofilm materials. The most researched gelatin-based membrane materials at home and abroad are mainly chitosan-gelatin co-blended membrane, gelatin-silk pigment co-blended membrane, polylactic acid-gelatin co-blended membrane and polyvinyl alcohol-gelatin co-blended membrane, etc. These blended materials greatly improve the physicochemical properties of gelatin, so that the gelatin-based polymer membrane materials are more functional.

Gelatin is a hydrophilic chemical substance, useful in histochemistry, bacterial culture medium and optical microscope radiation autoradiography.

3. Medical fibers. Improve the mechanical properties of gelatin-based medical fibers by blending and spinning other composites with gelatin.

4. Tissue repair and replacement. Gelatin-based composites used as tissue engineering scaffold materials and signal molecule carriers is currently one of the research hotspots of biomaterials.

Gelatin solution after crosslinking to form a hydrogel, in which the water for the porogenic agent, freeze-dried to form a porous scaffold material, and can be changed by changing the freezing parameters to adjust the pore rate and pore size. Therefore, according to different tissue repair requirements, the design of ideal gelatin-based tissue engineering materials.

5. Industrial gelatin. Used in the manufacture of fiber textile, insulating materials, paper, holographic materials, etc.

Uses of Gelatine.

According to the functional properties of gelatin, its use can be divided into two categories. One type uses its colloidal protective ability as a dispersant and is used in the production of polyvinyl chloride, photographic materials, bacterial culture and pharmaceuticals, and foodstuffs (such as candies, ice cream, cod liver oil capsules, etc.).

The other class utilizes its bonding ability as binder, which is used in paper making, printing, textile, printing and dyeing and electroplating and other industrial sectors. According to the different uses, the quality requirements of gelatine are also different.

Gelatin in the tape, paper containers, paper tubes, bookbinding and other aspects of the use of adhesives, adhesive strength is the main value factors; and used in photography, food, medicine and other fields, the importance of product purity. China's national standard for food gelatin GB6783-86, the use of the scope and the maximum use of GB2760-86.

Gelatin is a hydrophilic colloid, has the role of protecting the colloid, can be used as a hydrophobic colloid stabilizer, emulsifier. It is an amphoteric electrolyte, which can coagulate the charged particles into blocks in water, thus it can be used as clarifying agent for wine and alcohol.

As a dispersant, binder, thickener, stabilizer, emulsifier, it is widely used in photographic materials, pharmaceuticals, food, papermaking, printing, textile, printing and dyeing, electroplating, cosmetics, bacterial culture and so on.

Thickener; Stabilizer; Clarifier; Foaming agent. Gelatin is a hydrophilic colloid, with the nature of the protective colloid, can be used as a stabilizer and emulsifier for hydrophobic colloids.

It is also amphoteric electrolyte, so it can coagulate charged particles into blocks in aqueous solution, and can be used as clarifying agent for wine and alcohol.

Preparation of Gelatine.

1. Alkali method: the animal's bone and skin, etc. with lime emulsion fully impregnated with hydrochloric acid, neutralized, washed, boiled at 60 ℃ ~ 70 ℃ gelatin, and then through the antiseptic, bleaching, freezing, planing, drying and get. The finished product is called "B-type gelatin" or "alkali gelatin".

2. Acid method: the raw material is acidified in cold sulfuric acid solution with pH value of 1~3 for 2~8h, rinsed and soaked in water for 24h, then boiled at 50℃~70℃ for 4~8h, then frozen, extruded and dried. Finished product called "A-type gelatin" or "acid gelatin".

3. Enzymatic method: use protease to enzymatically dissolve the raw material skin and then treat it with lime for 24h, then neutralize it, boil it, concentrate it, freeze it and dry it.

Product Method of Bulk Gelatine Powder.

Alkali method will be fully impregnated with lime emulsion, such as animal bones and skins, and then neutralized with hydrochloric acid, washed, boiled at 60 ~ 70 ℃ gelatine, and then through the antiseptic, bleaching, freezing, slicing, drying and obtained. The finished product is called "B-type gelatin", or "alkali gelatin". Acid raw materials in the pH value of 1 ~ 3 cold sulfuric acid acid acidification 2 ~ 8h, rinsing and immersion in water for 24h, boiling gelatin at 50 ~ 70 ℃ for 4 ~ 8h, and then frozen gelatin, extrusion, drying and become.

Finished product called "A-type gelatin", or "acid gelatin". The enzyme method uses protease to dissolve the raw material skin enzymatically and then treat it with lime for 24h, and then it is neutralized, boiled, concentrated, frozen and dried.
