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 grain, chestnuts and soya frying, mixing of oyster plant, barley grains, oat grain and rye grain, 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 and provide for improvement and preservation of organoleptic properties of drink due to its enrichment with extractive substances of miscella.
