This can be particularly important in applications where the powder needs to be stored for long periods or exposed to humid conditions, as the presence of CMC can help to maintain the quality and functionality of the product.

In powder processing, CMC can also be used as a thickener and stabilizer in various formulations. Its ability to form a viscous solution makes it ideal for suspending and dispersing other ingredients in the powder, improving the overall consistency and texture of the final product. This can be particularly useful in applications where a smooth and uniform texture is desired, such as in powdered beverages or instant soups.

Furthermore, CMC can also act as a film-forming agent in powder processing, creating a protective barrier around the particles that helps to prevent them from clumping together or sticking to the packaging. This can be particularly important in applications where the powder needs to be reconstituted with water or other liquids, as the presence of CMC can help to maintain the integrity and appearance of the product.

Overall, the benefits of using CMC in spray-drying and powder processing are numerous. From improving flow properties and enhancing stability to acting as a binder and thickener, CMC can play a crucial role in enhancing the quality and functionality of the final product. Its versatility and effectiveness make it a valuable ingredient in a wide range of applications, making it a popular choice for manufacturers looking to improve the performance of their powders.
