FIELD: food industry.
SUBSTANCE: invention relates to technology of manufacturing coffee substitutes. The method of production of an instant powder for producing a flavoured yacon-pomegranate beverage involves extracting allspice with liquid nitrogen with separation of corresponding miscella, preparing yacon and pomegranate peel, cutting and drying them in the microwave files until their residual humidity is about 20%, roasting yacon, drying up the pomegranate peel by convection until its residual humidity is about 5%. The yacon and pomegranate peel are mixed in the mass ratio 7:3 by loading them into the cryomiller shell, the obtained mixture is impregnated by separated miscella with simultaneous pressure boost in the shell to the value corresponding to nitrogen saturation vapour pressure at the impregnation temperature and the pressure is released until it equals the atmospheric pressure with simultaneous freezing of the mixture and cryomilling of in the medium of evolved nitrogen.
EFFECT: production of a flavoured coffee drink out of unconventional raw materials according to a nonwaste technology.
