Yam polysaccharide is a bioactive carbohydrate fraction isolated from the tuber of Dioscorea opposita, a staple in traditional Chinese medicine and functional foods. Our extract is produced via hot water extraction and alcohol precipitation, retaining the natural polysaccharide profile. The resulting powder is standardized to a minimum 30% polysaccharide content (UV), ensuring consistent batch-to-batch quality for formulation use.
This product is supplied as a free-flowing, white to off-white powder that dissolves readily in hot water, making it suitable for liquid preparations, beverages, and solid dosage forms. It is intended for use in dietary supplements, functional foods, and nutraceutical R&D, where plant-derived polysaccharides are valued for their prebiotic and immunomodulatory properties.
