FIELD: food industry.
SUBSTANCE: invention refers to a manufacturing technique of coffee substitutes. It involves extraction of the aromatic herbal raw materials as provided by the versions of the method, in the liquid nitrogen medium and separation of appropriate miscella. Scorzonera is cut, dried in the microwave field to residual humidity approximately 20 % at microwave field power to ensure scorzonera heating to inside temperature 80-90°C for at least 1 hour, and roasted. Barley, oat and rye grains are roasted. Scorzonera, barley, oat and rye grains are mixed in the mass ratio 3:6:3:8. The prepared mixture is impregnated with separated miscella while pressurising to ensure proper saturated nitrogen vapour pressure at impregnation temperature, depressurising to air pressure with simultaneous freezing the mixture. It is followed with cryogrinding of the prepared mixture in the precipitated nitrogen medium.
EFFECT: preparation of a new coffee beverage of alternative raw materials.
