FIELD: food industry.
SUBSTANCE: invention is related to preservation industry. The method involves preliminary heating of fruits in jars with 60°C hot water during 2-3 min, subsequent pouring of 85°C syrup. Then the jars with fruits and syrup are put into the carrier ensuring air-tightness. Treatment thermal processes are performed by heating and cooling. During heating of jars with fruits, heating of some jars with fruits is performed simultaneously in baths with 75, 95 and 100°C water during 8, 8 and 25 minutes, respectively; cooling of already heated jars is performed in the same baths with 95 and 75°C water during 8 and 8 min with continuation of cooling in a 20-25°C atmospheric air flow at a rate of 7-8 m/s during 10 minutes. During each heat treatment process the jars with fruits are subjected to interrupted 2-3-minutes' turning upside down with a frequency equal to 0.33 sec-1 with a 2-3 minutes' interval.
EFFECT: method ensures the ready product quality enhancement along with simultaneous decrease of the production process duration.
