FIELD: food industry.

SUBSTANCE: invention relates to preservation industry, in particular, to methods for production of pear and quince compote in jars SKO 1-82-500. The method involves the fruits packing into the jars, subsequent pouring of the fruits with a 85°C hot water for 2-3 minutes. Then one performs replacement of the water with a 97-98°C syrup, the jars sealing, putting into the carrier ensuring mechanical air-tightness of the jars. Then the jars filled with fruits are sequentially heated in a 120°C air flow at a rate of 8-9 m/s during 8 minutes, showered with a 100°C water during 18 minutes with subsequent staged 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 jar filled with fruits is turned upside down with a frequency equal to 0.133 s^-1.

EFFECT: invention ensures enhancement of nutritive value of the ready product, decrease of boiled fruits quantity, prevention of thermal breakage of containers with simultaneous simplification of the thermal treatment process.
