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

FIELD: food industry.

SUBSTANCE: invention is related to preservation industry. The method is as follows: after packing fruits in jars one performs pouring with 85°C water for 2-3 minutes, proceeds with repeated pouring with 98°C water for 2-3 minutes, replacing water with a 98°C syrup. The jar is sealed, put into the carrier ensuring mechanical air-tightness and undergoes sterilisation with 100°C water during 12 -15 minutes. Then one performs cooling in 80°C water for 4 minutes, then - in baths with 60°C and 40°C water for 4 and 6 minutes respectively. During the heat treatment process the jars are turned upside down with a frequency equal to 0.1 s^-1.

EFFECT: method ensures reduction of heat treatment process duration, heat energy saving, preservation of the used raw materials natural components, air removal from the fruits and jar before the container sealing, decrease of quantity of boiled fruits, enhancement of the ready product food value, prime cost reduction and the ready product competitiveness increase.
