Yam (Dioscorea opposita) is well known for its exceptional nutritional properties and health benefits. Alfa Chemistry's yam dietary fiber is derived from high-quality yam through a specialized process that includes pre-gelatinization, gelatinization, expansion, drying, and milling. This results in a highly soluble, fine brown powder with a mildly sweet taste, making it an excellent ingredient for functional foods, beverages, and dietary supplements.
