What is manjakani extract powder?
Manjakani is the common name for the galls that form on the twigs of Quercus infectoria, an oak native to West Asia and long traded and used across the Malay world. The galls are naturally rich in tannins, which gives manjakani its characteristic astringency. Bionutricia’s manjakani extract powder is a 100:1 extract of the oak gall, concentrated and dried into a stable, free-flowing brown powder that dissolves fully in water and is standardized to 65–70% tannic acid, giving formulators a consistent, easy-to-handle raw material in place of variable raw galls.
What is it used for in formulation?
It is used as a bulk raw ingredient across several categories: herbal supplement premixes and sachet blends produced by brand owners, traditional-herbal teas and instant drink powders, functional and energy beverages, and other functional-food formats. Manjakani has a long heritage of traditional use in Malay and wider Asian herbal preparations, which supports its positioning in heritage-botanical and traditional-wellness products. The powder is fully water-soluble and typically dosed at 250–750 mg per serving, adjusted to the target format.
