METHOD FOR PRODUCTION OF CRYOPOWDER FROM PUMPKIN USING UHF ELECTROMAGNETIC FIELD AND SOLAR ENERGY Russian patent published in 2013 - IPC A23L1/25 A23L1/212 A23L2/385 A23L3/54 A23B7/01 

FIELD: food industry.

SUBSTANCE: invention relates to usage of UHF electromagnetic field and solar energy during production of pumpkin cryopowder. The method involves pumpkin cutting into pieces, removal of seed cells, treatment with UHF electromagnetic field with frequency equal to 2400±50 MHz and power equal to 300-450 W during 1.5-2.5 minutes with temperatures within the whole bulk of the pumpkin pieces reaching 78-83°C. The semi-product is dried with solar energy until moisture content is 8-10%. The dried semi-product is supplied into the cryomill to produce cryopowder that is packed.

EFFECT: method allows to produce pumpkin cryopowder with maximum preservation of biocomponents and inactivation of oxidation enzymes.
