    Abstract: This invention concerns the extraction of the water solubles of the dahlia tuber which contains aroma and flavor bodies and the concentration, drying, and roasting of these extracts to produce additional flavor bodies. The roasted and ground flavorsome beverage powders so produced can be used to make palatable beverages in hot or cold milk or water. Furthermore the above beverage powders can be blended in concentrations of 1 to 99% with the flavor powders of coffee, tea or cocoa to produce flavor powders that complement each other when used to make water or milk beverages.
