About Gelatin 

Gelatin is a protein substance derived from collagen, a natural protein present in the tendons, ligaments, and tissues of mammals. It is produced by boiling the connective tissues, bones and skins of animals, usually cows and pigs. Gelatin's ability to form strong, transparent gels and flexible films that are easily digested, soluble in hot water, and capable of forming a positive binding action have made it a valuable commodity in food processing, pharmaceuticals, photography, and paper production.

Gelatin Wide Application

Culinary uses

Probably best known as a gelling agent in cooking, different types and grades of gelatin are used in a wide range of food and non-food products: Common examples of foods that contain gelatin are gelatin dessertstriflesaspicmarshmallowscandy corn, and confections such as Peepsgummy bearsfruit snacks, and jelly babies. Gelatin may be used as a stabilizer, thickener, or texturizer in foods such asyogurtcream cheese, and margarine; it is used, as well, in fat-reduced foods to simulate the mouthfeel of fat and to create volume without adding calories.

Gelatin is used for the clarification of juices, such as apple juice, and of vinegar. Isinglass, from the swim bladders of fish, is still used as a fining agent for wine and beer.[7] Beside hartshorn jelly, from deer antlers (hence the name "hartshorn"), isinglass was one of the oldest sources of gelatin.

Technical uses

  • Certain professional and theatrical lighting equipment use colour gels to change the beam color. These were historically made with gelatin, hence the term color gel.
  • Gelatin typically constitutes the shells of pharmaceutical capsules in order to make them easier to swallow. Hypromellose is a vegetarian-acceptable alternative to gelatin, but is more expensive to produce.
  • Animal glues such as hide glue are essentially unrefined gelatin.
  • It is used to hold silver halide crystals in an emulsion in virtually all photographic films and photographic papers. Despite some efforts, no suitable substitutes with the stability and low cost of gelatin have been found.
  • Used as a carrier, coating or separating agent for other substances; for example, it makes beta-carotene water-soluble thus imparting a yellow color to any soft drinks containing beta-carotene.
  • Gelatin is closely related to bone glue and is used as a binder in match heads and sandpaper.
  • Cosmetics may contain a non-gelling variant of gelatin under the name hydrolyzed collagen.
  • Gelatin was first used as an external surface sizing for paper in 1337 and continued as a dominant sizing agent of all European papers through the mid-19th century. In modern times it occasionally found in some glossy printing papers, artistic papers, playing cards, and it maintains the wrinkles in crêpe paper.

Skin/Hide/Bone Gelatin Production Methods

Step 1: The material that actually becomes gelatin is collagen. This is only found in high enough concentrations to be useful inside skin and bones. As a result, the first step in gelatin production is cleaning the starter materials in KODI Gelatin washing tanks. Any leftover debris, such as fat, hair or meat, is thoroughly scrubbed from the skin and bones. This reduces the chance of contaminants, which creates a purer product and easier extraction.

Step 2: This next part of gelatin production is where the methods begin to diverge in KODI Gelatin acid tanks or KODI Gelatin Alkaline tanks. The base material is soaked in a solution, which begins to break down the links between the collagen and other materials using one of three basic soaking methods: acidic, alkaline and enzymatic. Acidic methods for gelatin production typically take one to two days and work the best on hides. Alkaline methods can take weeks but will work on nearly any valid material. Lastly, enzymatic processes are somewhat new but work very fast and produce high purity in the few places equipped to use them.

Step 3: The rest of the gelatin production process is done fairly quickly. After the soaking in KODI Gelatin soaking tanks, the collagen is pulled from the base material using water. Alkaline water will pull the material faster, but will also damage the gelatin, so neutral or acidic water is generally used. Heat will also damage the collagen but will generally pull out more material, so washing is done in waves. The process starts with cold water but gradually gets warmer to get as much out as possible.

Step 4: The last step processes the collagen into full-fledged gelatin. This part of gelatin production varies wildly based on the previous steps, but it typically involves cold temperatures, filtration and air drying systems. Here we normally need to use KODI gelatin membrane filter, KODI gelatin belt dryer/ Band dryer. Different pH levels and ambient temperatures during soaking have a large impact on the solidity and quantity of the final product. KODI company will supply you a Turnkey skin/hide/bone gelatin production line and Gelatin machinery.
