FIELD: food industry.
SUBSTANCE: invention is related to coffee substitutes production technology, namely to technology of manufacturing instant powder for flavoured coffee beverages. Orange peels are extracted by liquid nitrogen with corresponding miscella separation. Yacon is prepared and cut. Prepared yacon is dried in microwave oven till residual humidity about 20% at microwave field power providing warming of yacon inside the bits till temperature 80 - 90°C during at least an hour. Yacon and acorns are fried. Hereafter they are loaded together into cryomill in mass ratio 1 : 1, mixed; obtained mixture is impregnated with separated miscella with simultaneous pressure boost till pressure level of nitrogen saturated vapours at impregnation temperature. It is followed by depressurisation till atmosphere pressure with simultaneous freezing of mixture and its cryomilling in medium of evolved nitrogen.
EFFECT: method allows to produce flavoured coffee beverage according to nonwaste technology.
