FIELD: food industry.
SUBSTANCE: invention relates to technology of manufacturing coffee substitutes. Method involves orange peel extraction with liquid nitrogen with separation of the corresponding miscella, preparation and cutting of yacon, its drying in microwave field till residual humidity about 20% at the microwave field power providing warming of yacon inside the bits to 80-90°C for at least an hour and frying and drying of peach refuse in microwave field till residual humidity about 20% at the microwave field power providing warming of peach refuse inside the mass to 80-90°C for at least an hour and continual drying till residual humidity about 5% by convective method, mixing yacon and peach refuse at mass ratio 3:2, 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 enables to produce new flavoured coffee drink out of unconventional raw material according to nonwaste technology.
