FIELD: food industry. ^ SUBSTANCE: invention relates to technology in processing vegetable raw. Method involves disruption of juice-containing structures and separation of solid components from juice with pulp. Cobs are loaded into vacuum chamber and structures are disrupted by steam and juice at violent boiling, intensive change of pressure, continuous supply of heat, at temperature 60oC, not less. Steam is condensed to form distillate, juice concentrate is separated, solid components are rinsed with distillate and rinsing suspension is combined with the juice concentrate. Invention provides the more complete utilization of raw and to enhance quality of juice. ^ EFFECT: improved extracting method.
