FIELD: food industry.SUBSTANCE: invention is related to preservation industry. The method involves preliminary heating of fruits in jars filled with hot water with subsequent sealing, two-stage heating in 80 and 100°C water for 6 and 12-15 minutes respectively and subsequent two-stage cooling in 80°C water during 6 minutes in a 20-25°C atmospheric air flow at a rate of 7-8 m/s during 12 minutes. Heating and cooling are performed at temperature of 80°C in the same bath; during the heat treatment process, the jar is turned upside down with a frequency equal to 0.166 s.EFFECT: method ensures saving heat energy and water, the process duration reduction and the ready product quality enhancement.1 ex |
