FIELD: food industry.
SUBSTANCE: group of inventions relates to manufacturing technique of coffee substitutes. The methods envisage preparation of the recipe components, extraction of the vegetable raw material envisaged by the method versions with liquid nitrogen with separation of the corresponding miscella, oyster plant cutting, drying in microwave field at specified parametres of the process and frying. Barley grains, oat grains, acorns and nut kernels are fried. Oyster plant, barley grains, oat grains, acorns and nut kernels are mixed in ratio 3:7:3:4:3. Obtained mixture is impregnated by separated miscella performed with simultaneous pressure boost and depressurisation till atmosphere pressure with simultaneous freezing of mixture and its cryomilling in medium of evolved nitrogen. Mixture is cryomilled in medium of evolved nitrogen.
EFFECT: methods enable to obtain new flavoured coffee drink with improved organoleptic properties according to non-waste technology.
