Gelatin, usually produced from animal collagen by hydrolysis, purification, drying and other processes, is a multifunctional food additive widely used in the food industry and medicine. This article will introduce the many uses of gelatin film and show how it is widely used in our daily lives.
Firstly, its use in the food industry. Gelatin is ideal for making sweets such as fudge, jelly and marshmallows. It can provide the necessary gel structure to give the confection good elasticity and stability. In dairy products such as yogurt and puddings, gelatin can act as a stabilizer, helping the product to maintain a consistent texture and extend its shelf life. In meat products, gelatin film can increase the gelatin of meat products, improving their taste and stability, and is often used in the production of aspic, ham and sausages. In bakery products, gelatin can be used as a thickening agent to maintain the moisture and structure of cakes and desserts.
Secondly, it is used in the medical field. Gelatin is one of the main ingredients in the manufacture of pharmaceutical capsules. It is able to form a hard shell, protect the drug ingredients from the environment, and dissolve and release the drug in the appropriate environment in the body. In blood products, gelatin can be used as a stabilizer to help maintain the stability of blood products and extend their shelf life.
Finally, gelatin is also used in cosmetics as an ingredient in face masks and other skin care products to provide moisturising and nourishing effects. In traditional photography, gelatin was once used as a base material for film, although this use is now less common. Gelatin film can also be used to make edible packaging film, which has good gas resistance and biodegradability.
