SWEET CHERRY COMPOTE PRESERVATION METHOD Russian patent published in 2013 - IPC A23L3/02 

FIELD: food industry.

SUBSTANCE: invention is related to preservation industry. After packaging the fruits are heated during 120 sec by way of cyclic delivery of saturated 105-110°C water vapour into jars. Duration of vapour delivery cycles and vapour maintenance are 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 140°C. Then the jars are poured with a 85°C syrup, sealed and sterilised in an autoclave according to the preset mode with continuation of cooling in another autoclave or vessel.

EFFECT: invention allows to decrease sterilisation duration, reduce non-uniformity of thermal treatment due to the initial temperature increase, before sealing, ensure more complete preservation of vitamin C, better preservation of structural-and-mechanical and organoleptic characteristics of the ready product, enhancement of heat energy saving and the ready product quality.
