FIELD: food industry.
SUBSTANCE: group of inventions is related to food industry, namely to coffee substitutes production. 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 oyster plant, its drying in microwave field at specified parametres of the process and frying, barley grains and soya frying, mixing of oyster plant, barley grains 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: inventions allow producing of flavoured coffee drink instant powder out of unconventional raw material according to nonwaste technology.
