PEAR AND QUINCE COMPOTE PRESERVATION METHOD Russian patent published in 2012 - IPC A23L3/00 A23L3/04 

FIELD: food industry.

SUBSTANCE: invention relates to preservation industry. Jars filled with compote are put into the carrier ensuring air-tightness. Then one performs preliminary heating of the jars filled with compote by way of showering with 65-70°C hot water during 3 minutes, sterilisation in 80°C hot water during 5 minutes. One performs repeated subsequent showering with 90°C hot water during 3 minutes and sterilisation in 100°C hot water during 25-30 minutes. One performs subsequent cooling in an atmospheric air flow at a rate of 3-4 m/s during 6 minutes with continuation of cooling in an atmospheric air flow at a rate of 7-8 m/s. One proceeds with alternate application of a 65-70°C water film on the jar surface during 7 minutes and turning the jar upside down with a frequency equal 0.133 s^-1.

EFFECT: invention ensures significant saving of heat energy and water, the process duration reduction, the technological cycle continuality and the ready product quality enhancement.
