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. The method 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, sequentially heated in a 140°C air flow at a rate of 1.5 m/s during 10 minutes and showered with 100°C water during 10 minutes. Then one performs staged cooling in baths filled with 80°C water for 4 minutes, with 60°C water for 4 minutes, with 40°C water for 5 minutes. During the whole heat treatment process 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.
