Gelatin is a protein that is derived from the collagen found in animal skin, bones, and connective tissue. It is commonly used in food, pharmaceutical, and cosmetic industries due to its unique properties such as gelling, thickening, and stabilizing. Gelatin is a hydrophilic material, which means it can absorb and hold a large amount of water. When dissolved in hot water and cooled, gelatin forms a gel-like substance, which is commonly used in desserts, candies, and other food products. It is also commonly used in the pharmaceutical industry to make capsules, tablets, and other drug delivery systems. Additionally, gelatin is used in cosmetics such as face masks, hair care products, and nail polish removers due to its ability to form a film on the skin and hair. Gelatin is a versatile and useful ingredient that has many practical applications in various industries.
