FIELD: food industry.
SUBSTANCE: invention relates to technology of manufacturing coffee substitutes. Coriander is extracted by liquid nitrogen with corresponding miscella separation. Prepared yacon is cut and dried in microwave oven at preset process parametres till residual humidity about 20%. Yacon, barley grain, oat grain, acorns and nut kernels are fried, mixed in mass ratio 3:7:3:4:3 and loaded into cryomill basket. Obtained mixture is impregnated with separated miscella with simultaneous pressure boost in basket. After the impregnation the pressure is released and the mixture is frozen. The mixture is cryomilled in medium of evolved nitrogen.
EFFECT: product obtained from unconventional raw material with taste and aroma similar to flavoured coffee at mashing.
