CHERRY PLUMS, MIRABELLES AND CORNEL COMPOTE PRESERVATION METHOD Russian patent published in 2012 - IPC A23L3/04 

FIELD: food industry.

SUBSTANCE: invention is related to preservation industry. After packing one performs fruits pouring with 60°C water into jars during 2-3 minutes, with subsequent replacement of the water with 80-85°C syrup. Then the jars are sealed, put into the carrier ensuring mechanical air-tightness of the jars. The jars undergo heating by way of subsequent staged showering with 80°C water during 8 minutes and with 85°C water during 35 minutes with subsequent staged cooling by way of spraying with 80°C water during 8 minutes, with 60°C water during 8 minutes and with 40°C water during 10 minutes. During the whole heat treatment process the jars are turned upside down with a frequency equal to 0.33 s^-1.

EFFECT: invention ensures the heat treatment duration reduction, reduction of the residual air quantity in the jar before sealing, preservation of natural components of raw material used, reduction of cracked fruits quantity, enhancement of nutritive value of the ready product, prevention of thermal breakage of the jars and the heat-exchange process intensification.
