FIELD: food industry.
SUBSTANCE: invention relates to technology used to produce coffee substitutes. Method provides for preparation of recipe components, extraction of red tea by liquid nitrogen with corresponding miscella separation, yacon cutting, drying in microwave field 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 and frying, barley, oat and rye grains frying, mixing of yacon, barley, oat and rye grains in mass ratio 3:6:3:8, 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: method makes it possible to produce new flavoured coffee drink from non-traditional raw materials according to wasteless technology.
