FIELD: food industry.
SUBSTANCE: invention refers to process of manufacture of coffee substitutes. Anise-tree is extracted with liquid nitrogen and corresponding miscella is separated. Prepared and cut yacon is dried in field of SHF to residual moisture about 20% with power of SHF facilitating heating of chicory to temperature inside pieces 80-90°C during not less 1 hour and roasted. Yacon and roasted acorns at weight ratio 1:1 are charged into cryo-mill and mixed; produced mixture is soaked with separated miscella at simultaneous build-up of pressure to a value, corresponding to pressure of saturated vapours of nitrogen at temperature of soaking. Then pressure is dropped to atmospheric with simultaneous freezing of mixture; the mixture is cryo-milled in medium of precipitated nitrogen thus producing instant-powder.
EFFECT: method facilitates manufacture of new aromatised coffee drink out of non-traditional raw material by non-waste technology.
