1-Deoxy-D-glucitol is primarily used in the food industry as a low-calorie sweetener and sugar substitute. It is valued for its ability to provide sweetness without contributing significantly to caloric intake, making it suitable for diabetic and weight-management products. Additionally, it is employed in the production of sugar-free chewing gums, candies, and baked goods due to its stability under high temperatures and non-cariogenic properties, which help prevent tooth decay. In the pharmaceutical sector, it serves as an excipient in tablet formulations, aiding in the stabilization and enhancement of drug delivery systems. Its humectant properties also make it useful in cosmetics and personal care products, where it helps retain moisture and improve skin hydration.
