METHOD FOR BAROVACUUM DRYING OF MUSHROOMS Russian patent published in 2020 - IPC A23L31/00 

FIELD: food industry.

SUBSTANCE: invention relates to food industry, in particular, to production of dry mushrooms. Method involves raw materials purification, milling and drying. Drying is carried out in a barovacuum chamber, with layer thickness of 30–40 mm and heating of not more than 40 °C, by alternating two cycles: in vacuum cycle, duration of 15 minutes, residual pressure is 5 kPa, product is heated by infrared lamps, and in the discharge cycle, duration of 10 minutes, dry steam with temperature of 40 °C is injected into the chamber and the product is held under excessive pressure of 50 kPa, the infrared lamps are switched off at the same time. Total time of mushrooms drying does not exceed 180 minutes.

EFFECT: proposed invention allows to exclude thermal denaturation of thermolabile components and produce dry mushrooms of high quality with high content of biologically active substances.
