APPLE COMPOTE PRESERVATION METHOD Russian patent published in 2015 - IPC A23L3/00 

FIELD: food industry.

SUBSTANCE: invention relates to preservation industry and may be used for apple compote preservation. The method is as follows: after packaging into jars, fruits are heated during 80 sec by way of cyclic delivery of saturated 105-110°C water vapour into jars; duration of vapour delivery cycles and vapour maintenance is equal to 10 sec and 10 sec respectively. During the whole vapour delivery process, the external surface of the jar is blown over with air heated up to 130-140°C at a rate of 4-5 m/sec. Then the jars are poured with 95-98°C syrup, sealed, put into the carrier ensuring air-tightness; then one performs jars heating by way of staged showering with 90°C water during 8 minutes and 110°C calcium chloride solution during 12 minutes with subsequent spraying with 90, 70, 50 and 35°C water during 6, 5, 5 and 5 minutes.

EFFECT: invention ensures sterilisation duration reduction and thermal treatment non-uniformity decrease, prevents thermal breakage of jars as well as enhances the ready product quality.
