description Product Description
Used extensively in the food industry as a sweetener and filler in baked goods, confectionery, and dairy products. It enhances texture and bulk in powdered foods like infant formula and protein supplements. In pharmaceuticals, it serves as an excipient in tablet and capsule formulations, improving stability and compressibility. Also utilized in microbiology as a nutrient in culture media for bacterial growth. Its low hygroscopic nature makes it ideal for dry powder inhalers in respiratory medications. Additionally, it is employed in the production of biodegradable plastics and as a carrier in animal feed.
