PRODUCTION METHOD OF FLAVOURED YAKON-GRAPE DRINK Russian patent published in 2010 - IPC A23F5/44 

FIELD: food industry.

SUBSTANCE: production method of instant powder for production of flavoured yacon-grape beverage provides for extraction of dill seeds by liquid nitrogen with corresponding miscella separation, preparation and cutting of yacon, its drying, roasting and drying of grape refuse. Yacon and grape refuse are mixed in the mass ratio 3:2 by loading them into the cryomiller shell. The obtained mixture is impregnated by separated miscella with simultaneous pressure boost in the shell to achieve the pressure corresponding to the nitrogen saturation vapour pressure at the impregnation temperature and pressure release until the pressure equals the atmospheric pressure simultaneously freezing the mixture and cryomilling it in the medium of evolved nitrogen.

EFFECT: method enables to produce new flavoured coffee drink out of unconventional raw material according to nonwaste technology.
