FIELD: food industry.

SUBSTANCE: invention relates to the canning industry and can be used in canning compotes. Method is characterized by fruits laid in the jar are heated by cycling the saturated water vapour at a temperature of 105-110°C for 100 s. Duration of the cycles of steam and its holding is 10 and 10 s, respectively, while during the whole process of steam supply, the outer surface of the cans is blown by a stream of air at a speed of 5-6 m/s, heated to a temperature of 110-120°C. After this, a syrup of 95-97°C is poured into the cans, subject them to pre-inflation with lids and heating in a stream of air at a temperature of 140°C and a speed of 6.5-7 m/s for 5 minutes to 90-92°C with subsequent addition and continuation of heating in water with a temperature of 100°C for 10 min to 98°C with further stepwise cooling in water with temperatures of 80, 60 and 40°C, respectively, for 5, 5 and 5 minutes.

EFFECT: invention makes it possible to reduce the duration of sterilization, to reduce the unevenness of heat treatment, to prevent the thermal battle of the cans, and to improve the quality of the finished product.
