FIELD: food industry.
SUBSTANCE: invention relates to technology of coffee substitutes production, namely to production of instant powder to produce yacon-apple drink. Method provides for extraction of orange rind with liquid nitrogen to separate according miscella, yacon cutting, drying in microwave field at specified parametres of the process and frying, apples cutting, drying in microwave field at the specified parametres of the process and their additional convective drying, mixing of yacon and apples, impregnation of produced mixture with separated miscella with simultaneous increase of pressure, pressure collapse down to atmospheric one with simultaneous freezing of mixture and its cryo-grinding in medium of released nitrogen.
EFFECT: method makes it possible to produce new flavoured coffee drink from non-traditional raw materials according to wasteless technology.
