FIELD: food industry.
SUBSTANCE: invention is related to biotechnology, namely to technology of coffee substitutes production. Method provides for preparation of recipe components, extraction of tangerine peel by liquid nitrogen with corresponding miscella separation, yacon cutting, drying in microwave field at preset process parametres and frying, barley, oat and rye grains frying, mixing of yacon, barley, oat and rye grains, 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 with improved organoleptic properties by means of its enrichment with extractive substances of miscella and their preservation.
