FIELD: food industry.
SUBSTANCE: invention relates to technology of manufacturing coffee substitutes. The method provides for preparing the ingredients, extracting peach refuse by liquid nitrogen with corresponding miscella separation, cutting and drying yacon in the microwave field at preset process parametres as well as roasting yacon, roasting barley, oat and rye grain, mixing the yacon, barley, oat and rye grain, impregnating the obtained mixture by separated miscella along with a simultaneous pressure boost and releasing the pressure until it equals the atmospheric pressure simultaneously freezing the mixture and cryomilling it in the medium of evolved nitrogen.
EFFECT: production of a new flavoured coffee drink out of unconventional raw materials according to nonwaste technology.
