FIELD: food industry.
SUBSTANCE: invention is related to preservation industry. The method involves preliminary heating of fruits with hot 80°C water during 2 minutes with subsequent replacement of water with 95°C syrup, sealing and sterilisation in 130°C air flow at a rate of 1.5-2 m/sec during 18 minutes with subsequent maintenance during 3 minutes at a temperature of 105°C. Then one performs cooling in 20-25°C air flow at a rate of 7-8 m/sec during 12 minutes. During the heat treatment process the jar is subjected to interrupted 2-3-minutes' turning upside down with a frequency equal to 0.1 sec-1 with a 2-3 minutes' interval.
EFFECT: proposed method ensures prevention of the process of mechanic straining of fruits against each other and preservation of their integrity as well as economy of heat energy and water.
