QUINCE COMPOTE PRESERVATION METHOD Russian patent published in 2015 - IPC A23L3/02 

FIELD: food industry.

SUBSTANCE: method involves fruits preparation and packing with subsequent treatment in microwave field with 2400+50 MHz frequency during 1.0-1.5 min. Then the fruits are poured with 95°C syrup, repeatedly treated in microwave field; the jars contents are heated up to 90°C and sealed. Then jars are put into the carrier ensuring mechanical air-tightness, heated in 115°C dimethylsulfoxide solution during 8 minutes with subsequent cooling in a bath filled with 85°C water during 4 minutes, then - with 60°C water during 4 minutes and with 40°C water during 5 minutes. During the heat treatment process the jars are turned upside down with a frequency equal to 0.133 s^-1.

EFFECT: more complete preservation of biologically active components contained in the initial raw materials and reduction of the process duration allow to save heat energy and water.
