SWEET CHERRY PRODUCTION METHOD IN SWEET CHERRY JUICE Russian patent published in 2020 - IPC A23L3/00 A23L3/04 

FIELD: food industry.

SUBSTANCE: invention relates to preservation industry and may be used for production of preserved products. Method for production of sweet cherry in sweet cherry juice envisages packaging of fruits into jars, field of which is subjected to heating during 100 s by means of cyclic supply of saturated water vapour with temperature of 105–110 °C into jars. Duration of steam supply and holding cycles is 10 s and 10 s, respectively, wherein during the whole process of steam supply, the outer surface of the jars is blown by air heated to temperature of 110–120 °C and rate of 5–6 m/s. Then cherry juice is poured into jars with temperature of 95–97 °C, subjected to preliminary puffing and heating in air flow with temperature of 140 °C and speed 8 m/s during 8 minutes with subsequent addition of heating and continuing in water at temperature 100 °C for 10 minutes with further stepped cooling in water with temperature 80, 60 and 40 °C respectively for 5, 5 and 5 minutes.

EFFECT: proposed sweet cherries production method in sweet cherry juice ensures the process duration reduction, preservation of the product biologically active components, its quality enhancement due to the boiled and cracked fruits quantity reduction, prevents thermal breakage of jars and provides possibility of heat treatment of jars in devices of open type without creation of back pressure in apparatus and without application of carriers for mechanical sealing of jars in process of heat treatment, and also expands range of preserved food of this type.
