FIELD: food industry.
SUBSTANCE: invention is related to preservation industry. The method involves preliminary heating of fruits with 85°C hot water during 3 minutes with subsequent sterilisation in 140°C air flow at a rate of 1.5-2 and 8-8.5 m/s during 5 and 8 minutes, respectively, with subsequent maintenance at a temperature of 105°C during 3 minutes and cooling in 20-25°C air flow at a rate of 7-8 m/s during 15 minutes. During the whole heat treatment process the jars are subjected to interrupted 2-3-minutes' turning upside down with a frequency equal to 0.133 sec-1 with a 2-3 minutes' interval.
EFFECT: invention allows to reduce the process duration, preserve biologically active components of raw materials used and improve structural-and-mechanical characteristics of the ready product.
