PEAR AND QUINCE COMPOTE STERILISATION METHOD Russian patent published in 2012 - IPC A23L3/00 

FIELD: food industry.

SUBSTANCE: invention relates to preservation industry and may be used for compote preservation. After preliminary preparation and packing of fruits into jars one performs pouring with 80°C water for 2-3 minutes. Then the water is replaced with 95-97°C syrup; the jars are sealed, put into the carrier ensuring mechanical air-tightness and undergo thermal sterilisation involving sequential heating by way of staged showering with 80°C water during 4 minutes and with 100°C water during 15 minutes. The jars are cooled by way of spaying with 80°C water during 4 minutes, with 60°C water during 4 minutes and with 40°C water during 4 minutes; during the whole heat treatment process the jar is turned upside down with a frequency equal to 0.1 s^-1.

EFFECT: method ensures saving heat energy and water, the process duration reduction and simplification, prevention of thermal breakage of jars, the ready product quality improvement.
