FIELD: food industry.

SUBSTANCE: method involves fruits preparation and packing with subsequent treatment in microwave field with 2400+50 MHz frequency during 2.5-3.0 min. Then the fruits are poured with 85°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 12 minutes with subsequent cooling in a bath filled with 85°C water during 8 minutes, then - with 60°C water during 8 minutes and with 40°C water during 10 minutes. During the heat treatment process the jars are turned upside down with a frequency equal to 0.33 s^-1.

EFFECT: invention allows to reduce boiled and cracked fruits quantity and the process duration as well as preserve biologically active components of raw materials used.
