Hypromellose (hydroxypropyl methylcellulose or HPMC) is used as a food additive in various applications, primarily as a thickener, stabilizer, emulsifier, and film-forming agent. While not as common as in medicine or cosmetics, HPMC has several approved uses in the food industry. Here are some key applications of HPMC in food:

Thickening Agent: HPMC is used to thicken food products, providing viscosity and texture. It helps improve the mouthfeel and consistency of sauces, gravies, soups, dressings, and puddings.

1. Stabilizer and Emulsifier: HPMC stabilizes food products by preventing phase separation and maintaining uniformity. It can be used in dairy products like ice cream and yogurt to improve texture and prevent ice crystal formation. HPMC also serves as an emulsifier in salad dressings, mayonnaise, and other emulsified sauces.
2. Film-Forming Agent: HPMC forms a thin, flexible film when applied to the surface of food products. This film can provide a protective barrier, improve moisture retention, and extend the shelf life of certain food items, such as fresh fruits and vegetables.
3. Gluten-Free Baking: In gluten-free baking, HPMC can be used as a binder and structural enhancer to replace the gluten found in wheat flour. It helps improve the texture, elasticity, and crumb structure of gluten-free bread, cakes, and pastries.
4. Fat Replacement: HPMC can be used as a fat replacer in low-fat or reduced-fat food products to mimic the mouthfeel and texture provided by fats. It helps enhance the creaminess and viscosity of products like low-fat dairy desserts, spreads, and sauces.
5. Encapsulation of Flavor and Nutrients: HPMC can be used to encapsulate flavors, vitamins, and other sensitive ingredients, protecting them from degradation and improving their stability in food products.
6. Coating and Glazing: HPMC is used in food coatings and glazes to provide a glossy appearance, enhance texture, and improve adhesion to food surfaces. It is commonly used in confectionery products like candies, chocolates, and glazes for fruits and pastries.
7. Texturizer in Meat Products: In processed meat products like sausages and deli meats, HPMC can be used as a texturizer to improve binding, water retention, and slicing properties.

It’s important to note that the use of HPMC in food is subject to regulatory approval in each country or region. Food-grade HPMC must meet strict safety and quality standards to ensure its suitability for use in food products. As with any food additive, proper dosage and application are essential to maintain the safety and quality of the final food product.
