METHOD OF PRODUCING COMPOTE FROM GRAPES Russian patent published in 2018 - IPC A23L3/02 A23L2/42 

FIELD: food industry.

SUBSTANCE: method of producing compote from grapes includes preparation and packaging of grapes in jars followed by treatment in a microwave field with a frequency of 2400 ± 50 MHz for 2.0 minutes. Grapes are then filled with syrup at 98 °C, re-treated with a microwave field, and the contents of the jars are heated to 90 °C and sealed. Jars are then sterilised in water at 95 °C for 20 minutes, without creating back pressure in the apparatus, while the jars are in an "upside down" position. Further, the jars are cooled for 22 minutes in water, reducing their temperature from 95 to 40 °C.

EFFECT: method reduces duration of heat treatment, thereby improving the quality of the finished product.
