FIELD: food industry.
SUBSTANCE: group of inventions relates to manufacturing technique of coffee substitutes. Methods provide for preparation of recipe components, extraction of the aromatic vegetable raw material envisaged by the method versions by liquid nitrogen with corresponding miscella separation, oyster plant cutting, drying in microwave field at preset process parametres and frying, barley grains, rye grains frying, mixing of oyster plant, barley grains, 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: methods make it possible to produce new flavoured coffee drink with improved organoleptic properties by means of its enrichment with extractive substances of miscella and their preservation.
