FIELD: food industry.

SUBSTANCE: invention is intended for usage in preservation industry. The method for production of pear and quince compote in jar SKO 1-82-500 envisages fruits pouring with 85°C hot water for 2-3 minutes, subsequent replacement of the water with 85°C syrup. Then the jars are sealed, put into the carrier ensuring mechanical air-tightness of the jars. Then the jars are sequentially heated in a 150°C air flow at a rate of 5-6 m/s during 3 minutes, showered with 100°C water during 15 minutes with subsequent stage cooling in baths with 80°C water during 4 minutes, with 60°C water during 4 minutes and with 40°C water during 5 minutes. During the whole process of heat treatment the jars are turned upside down with a frequency equal to 0.133 s^-1.

EFFECT: invention ensures thermal energy saving and the ready product quality enhancement due to heat treatment duration reduction and uniformity.
