Applications of Gellan Gum

(1).Eat gelatin. It is an important ingredient and additive in the food industry. It is often used as a gelling agent, stabilizer, emulsifier, thickener and clarifying agent in the production of meat products, cakes, ice cream, beer, juice, etc.

(2).Biofilm material. The most studied gelatin base film materials are mainly chitosan-gelatin blend film, gelatin-silk fibroin blend film, polylactic acid-gelatin blend film and polyvinyl alcohol-gelatin blend film, etc. These mixed materials are greatly improved. The physical and chemical properties of gelatin make the gelatin-based polymer film material more functional.

(3).Medical fiber. The blending of other composite materials with gelatin improves the mechanical properties of gelatin-based medical fiber materials. Tissue repair and replacement.

(4).Industrial gelatin. Used in the manufacture of fiber textiles, insulating materials, paper, holographic materials, etc.

Raw material finishing: sort different kinds of raw materials, such as cow leather and pig skin; Wet skin and dry skin shall be separated, and substandard skin shall be picked out for further treatment. The fur can be soaked in 5% lime milk or 0.5 ~ 1% vulcanization solution to remove the fur. The fat layer of fresh pig skin should be scraped off. Soak the dry skin in clean water.

Lime water pre immersion: put the finished leather raw materials into about 1% lime water for immersion for 1 ~ 2D, and then cut them into small pieces. Hydraulic decontamination: continuously add the skin and water into the hydraulic degreaser, and clean the fat and dirt by using the hydraulic impact and the mechanical action of high-speed hammer. Lime water impregnation: put the degreased skin into the impregnation tank and impregnate it with 2 ~ 4% lime water (specific gravity 1.015 ~ 1.035). The ratio of wet skin to water is 1:3 ~ 4, and the pH value is 12.0 ~ 12.5. The best temperature is 15 ºC, and the time is 15-90d. When the temperature is high, the concentration of lime water can be lower, and when the temperature is low, the concentration can increase. This process is called "hair skin"; It is one of the key processes in gelatin production. Washing and neutralization: after the skin block expands, take it out and wash it fully with water. After washing for many times, the final pH is 9.0 ~ 9.5. After washing, neutralize the remaining lime with acid, first add water to immerse the raw materials, and wash it with water under continuous stirring. Generally, it takes 8 ~ 12h to complete.

Glue boiling and concentration: first put hot water into the glue pot, and then pour in the raw materials. Be careful not to make the skin stick into a ball. At the same time, slowly raise the temperature to 55 ~ 65 ºC, and release the glue juice after hot soaking for 6 ~ 8h; Then add hot water into the pot to increase the water temperature by 5 ~ 100 ºC compared with the previous time, continue to boil the glue, and so on, for many times, and the temperature increases gradually each time, and the last time can be boiled. At about 600 ºC, the obtained thin glue juice is filtered by a plate and frame filter press with filter cotton, activated carbon or diatomite as filter aid, and the clear glue liquid is obtained.

The glue liquid is separated by a centrifuge to further remove impurities such as oil and grease. Then put the glue solution into the vacuum concentration tank and control the temperature to 65 ~ 700 ºC for evaporation and concentration. When the glue solution becomes thick, it can be changed to 60 ~ 650 ºC to continue vacuum concentration. Master the concentration of glue according to the quality of glue and the conditions of drying equipment. For example, when drying with cold and hot air air conditioning, the specific gravity of glue concentration is 1.050 ~ 1.080 (500 ºC), and the glue content is 23 ~ 33%. The gel is dried, concentrated by glue, and heated by adding a certain amount of hydrogen peroxide, sulfite or Paraben, which is both bleached and preservative. Drop the concentrated glue on the cold roll to form a thin glue strip, scrape it in the container and transport it to the drying bed for drying. When the hot and cold air is dried to gel at 10~12 C, the product is then crushed. It is also possible to obtain semi-circular spherical rubber particles after dropping the concentrated rubber liquid on the drum and drying.
