FIELD: food industry.SUBSTANCE: invention is related to preservation industry. The method involves fruits preparation and packing with subsequent treatment in microwave field with 2400+50 MHz frequency during 1.5-2.0 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 12 minutes with subsequent cooling in a bath filled with 85°C water during 6 minutes, then - with 60°C water during 6 minutes and with 40°C water during 6 minutes. During the heat treatment process the jars are turned upside down with a frequency equal to 0.166 s.EFFECT: invention allows to reduce the process duration, preserve biologically active components of raw materials used, reduce boiled and cracked fruits quantity, prevent thermal breakage of jars during heat treatment with usage of high temperature heat carriers. |
