FIELD: food industry.

SUBSTANCE: invention is related to preservation industry. The proposed method for sterilisation of pear and quince compote in jars SKO 1-82-1000 involves heating in an air flow at 120-122°C at a rate of 6 - 7 m/s during 22 minutes with subsequent maintenance during 22-32 minutes at heated air temperature equal to 92-95°C and cooling in an atmospheric air flow at 25-28°C at a rate of 7-8 m/s during 18 minutes. During the heat treatment process the jar is subjected to interrupted 2-3-minute turning upside down with a frequency equal to 0.166 s^-1 with a 2-3 minutes interval.

EFFECT: method ensures significant saving of heat energy and water, preservation of biologically active components of raw materials and decrease of boiled and cracked fruits quantity.
