FIELD: food industry.
SUBSTANCE: invention relates to technology of manufacturing coffee substitutes. Method provides for extraction of green tea by liquid nitrogen with corresponding miscella separation, chicory preparation and cutting, its drying in microwave field till residual humidity about 20% at microwave field power providing warming of chicory inside the bits till temperature 80-90°. After that drying of tangerine refuses in microwave oven till residual humidity about 20% at microwave filed power providing warming inside the bits till temperature 80-90° is performed during at least an hour and drying till residual humidity about 5 % by convective method. Chicory and tangerine refuses are mixed in mass ratio 7:3, impregnation of obtained mixture by separated miscella is performed with simultaneous pressure boost and depressurisation till atmosphere pressure with simultaneous freezing of mixture and its cryomilling in medium of evolved nitrogen.
EFFECT: invention allows to obtain new coffee substitute with increased organoleptical properties according to nonwaste technology.
