FIELD: food industry.
SUBSTANCE: invention relates to food industry. The method envisages packing fruits into jars. Prepared fruits are packed and treated in microwave field with a frequency equal to 2400±50 MHz during 0.8-1.0 minutes. Then the treated fruits are poured with syrup heated up to 80-85°C. The jars are sealed, put into the carrier ensuring mechanical air-tightness of the jars and heated in 80°C hot water for 5 min with subsequent transfer into 100°C water for 13 minutes. Then the jars are cooled down with 90 - 40°C water during 15 minutes. During the heat treatment process the jars are turned upside down with a frequency equal to 0.1 s-1.
EFFECT: invention allows to reduce thermal treatment duration and decrease treatment non-uniformity.
