FIELD: food industry.
SUBSTANCE: invention relates to technology used to produce coffee substitutes. Method provides for extraction of lemon rind by liquid nitrogen with separation of according miscella, cutting of yacon, its drying in microwave field at specified parametres of the process and frying, apples cutting, drying in microwave field at specified parametres of the process and additional convective drying, black chokeberry drying in microwave field at specified parametres of the process and additional convective drying, mixing of yacon, apples and black chokeberry, impregnation of produced mix by separated miscella with simultaneous increase of pressure, pressure reduction down to atmospheric one with simultaneous freezing of mix and its cryo-grinding in medium of released nitrogen.
EFFECT: method makes it possible to produce new flavoured coffee drink from non-traditional raw materials according to wasteless technology.
