PEAR AND QUINCE COMPOTE STERILISATION METHOD Russian patent published in 2012 - IPC A23L3/04 

FIELD: food industry.

SUBSTANCE: invention relates to preservation industry and may be used for pear and quince compote preservation. After packaging fruits into jars one performs the fruits pouring with 80°C water during 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 of the jars and undergo thermal treatment by way of sequentially staged showering with 80°C water during 5 minutes and with 100°C water during 18 minutes with subsequent cooling by way of spraying with 80°C water during 5 minutes, with 60°C water during 5 minutes and with 40°C water during 5 minutes; during the whole process of heat treatment the jar is turned upside down with a frequency equal to 0.133 s^-1.

EFFECT: invention implementation ensures saving heat energy and water, the process duration reduction, the technological cycle continuality and the products quality enhancement.
