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. Girasol-sunflower is cut, dried in the microwave field to residual humidity approximately 20 % at microwave field power to ensure girasol-sunflower heating to inside temperature 80-90°C for at least 1 hour, and roasted. Also barley and soya grains are dried. Girasol-sunflower, barley and soya grains are mixed in the mass ratio 4:11:5. The prepared mixture is impregnated with separated miscella while pressurizing to ensure proper saturated nitrogen vapour pressure at impregnation temperature. Then depressurisation to air pressure with simultaneous freezing and cryogrinding of the mixture in the precipitated nitrogen medium follow.
EFFECT: methods allow preparing a new coffee flavoured beverage of alternative raw materials, and also improving organoleptic characteristics of the beverage ensured by enrichment with miscella extractants and their preservation.
