FIELD: food industry.
SUBSTANCE: method involves extraction of orange rind with liquid nitrogen with corresponding miscella separation, cutting, drying of yacon in a microwave field at preset process parametres and roasting it. Then apples are cut, dried in the microwave field at preset process parametres and dried up by convection. Black chokeberry is dried in microwave filed at preset process parametres and dried up by convection, yacon is mixed with apples and black chokeberry. After that the obtained mixture is impregnated by separated miscella with simultaneous pressure boost and pressure releases until the pressure equals the atmospheric pressure simultaneously freezing the mixture and cryomilling it in the medium of evolved nitrogen.
EFFECT: method enables to produce new flavoured coffee drink out of unconventional raw material according to nonwaste technology.
