It is commonly incorporated into functional foods, such as yogurt, cereal bars, and beverages, to improve texture and provide a low-calorie sweetening effect. In the pharmaceutical industry, it serves as a prebiotic ingredient in formulations aimed at supporting gut microbiota balance and overall wellness. Additionally, it is utilized in cosmetics and skincare products for its moisturizing and skin-conditioning properties. Its ability to act as a stabilizer and fat replacer also makes it valuable in low-fat or sugar-free food formulations.
