FIELD: food industry.
SUBSTANCE: invention relates to technology of manufacturing coffee substitutes. Method involves preparing recipe ingredients, extracting tangerine peel with liquid nitrogen with corresponding miscella separation, cutting girasol-sunflower, drying and roasting it and roasting acorns. Girasol-sunflower is dried in microwave field till residual humidity about 20% at microwave field power providing warming of girasol-sunflower inside the bits till temperature 80-90°C during at least an hour. Girasol-sunflower and acorns are mixed in mass ratio 1:1. The obtained mixture is impregnated by separated miscella with simultaneous pressure boost. The pressure is released until it equals the atmospheric pressure along with mixture freezing. Then, the mixture is cryomilled in medium of evolved nitrogen.
EFFECT: method enables to produce new flavoured coffee drink out of unconventional raw material according to nonwaste technology.
