HPMC, also known as Hydroxypropyl Methylcellulose, is a type of cellulose ether that is commonly used as a thickener, emulsifier, and stabilizer in the food industry. It is derived from cellulose, which is a natural polymer found in plants, and is commonly used as an ingredient in a variety of food products, including dressings, sauces, ice cream, and baked goods.

In the food industry, HPMC is valued for its ability to improve the texture and stability of food products, as well as its ability to enhance the appearance and mouthfeel of these products. Additionally, HPMC is commonly used as a fat replacer in low-fat and reduced-calorie foods, as it can mimic the texture and mouthfeel of fat while providing fewer calories. HPMC is also considered to be a safe ingredient and is approved for use in food by various regulatory agencies, including the U.S. Food and Drug Administration (FDA).
