FIELD: food industry.
SUBSTANCE: invention is related to preservation industry. After preliminary preparation and packaging of fruits into jars one performs pouring with hot 85°C water for 2-3 minutes, replacing water with a 95°C syrup. Then the jars are sealed and put into the carrier ensuring mechanical air-tightness. One performs simultaneous staged heating of some jars in baths filled with 75, 95 and 100°C water during 4, 4 and 5-8 minutes respectively and cooling of other jars in the same bath filled with 95 and 75°C water during 4 and 4 minutes with continuation of cooling in a 20-25°C atmospheric air flow at a rate of 7-8 m/s during 6 minutes. During the heat treatment process, the jar is turned upside down with a frequency equal to 0.1 s-1.
EFFECT: invention ensures saving heat energy and water, the process duration reduction and the ready product quality enhancement.
