maltitol is sugar substitute in food products labeled as "sugar-free" or "low-sugar." It's derived from maltose through hydrogenation and has a similar sweetness to sucrose (table sugar) but with fewer calories and a lower glycemic index. In food production, maltitol serves as a bulking agent, sweetener, and humectant, providing sweetness, texture, and moisture retention to products like candies, chocolates, baked goods, and sugar-free desserts
