FIELD: food industry.

SUBSTANCE: invention relates to a method for sterilisation of pumpkin and apple puree in jars. The method envisages putting jars with puree (after sealing) into the carrier, preliminary heating in the first bath filled with 80°C water during 5 minutes, subsequent transfer into the second bath filled with 100°C water for 5 minutes and into the third bath filled with 120°C calcium chloride solution for 20 minutes with subsequent cooling in the second bath and in the first one filled with 100 and 80°C water during 5 and 5 minutes, respectively, and with continuation of cooling in the fourth bath at water temperature equal to 60-40°C during 10 minutes; the jars heating and cooling are simultaneously performed in the same baths. During the whole process of the heat treatment, the jars are turned upside down with a frequency equal to 0.1 s^-1.

EFFECT: method ensures reduction of the heat treatment process duration, simplification of the heat treatment process performance and the heat sterilisation apparatus design.
