FIELD: food industry.
SUBSTANCE: invention refers to process of manufacture of coffee substitutes. The method consists in extracting lemon rind with liquid nitrogen, in separating corresponding miscella, in preparing, cutting and drying of yacon in field of SHF at specified parametres of the process to residual moisture contents 20%, in roasting yacon, in drying peach marc in field of SHF at specified parametres of the process to residual moisture content 20% and in convective finish drying it to residual moisture content 5%; in mixing yacon and peach marc, in soaking produced mixture with separated miscella at simultaneous pressure build-up, in pressure drop to atmospheric and in simultaneous freezing of mixture with cryo-milling it in medium of precipitated nitrogen.
EFFECT: facilitating production of new aromatised coffee drink out of non-traditional raw material by non-waste process.
