FIELD: food industry.
SUBSTANCE: group of inventions relates to manufacturing technique of coffee substitutes. The methods provide for preparation of recipe components, extraction of flavoured vegetable raw material envisaged by the method versions by liquid nitrogen with separation of according miscella, cutting yacon, its drying in microwave field at specified parametres of the process and frying, barley grains, oat grains, acorns and soya frying, mixing of yacon, barley grains, oat grains, acorns and soya, impregnation of the produced mixture by separated miscella with simultaneous increase of pressure, pressure reduction down to atmospheric one with simultaneous freezing of mixture and its cryo-grinding in medium of released nitrogen.
EFFECT: methods make 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.
