What is Chinese Yam / Shan Yao extract powder?
Chinese Yam (Dioscorea polystachya) is a climbing tuber crop long valued in East-Asian cuisine and traditional food practice, where the tuber — Shan Yao — is used in soups, tonics and congee. Bionutricia's Shan Yao extract powder is a 100:1 concentrate of the tuber, spray-dried into a stable, fine, free-flowing off-white powder using green-biotechnology extraction. For formulators this means a consistent, easy-to-transport, water-soluble raw material — simple to dose and store — in place of variable fresh-tuber inputs.
What is it used for in formulation?
It is used as a phytonutrient raw ingredient in health supplements and in beverages, chocolates, desserts and energy drinks, dosed at 200–500 mg or on a quantum-satis basis. As a water-soluble concentrate it disperses easily into both powder and liquid systems. Brand owners and manufacturers formulate it into their chosen finished format — capsules, tablets, sachets, functional beverages or food — while Bionutricia supplies the bulk ingredient for B2B formulation.
