METHOD OF PRODUCING CRANBERRY FOOD PRODUCT Russian patent published in 2024 - IPC A23B7/05 

FIELD: food industry.

SUBSTANCE: disclosed is a method for the production of a cranberry food product, comprising the stages of raw material preparation, drying to intermediate moisture content, holding under pressure, depressurisation, additional drying till dry substances content is not less than 85%, packing in airtight package in oxygen-free medium. Drying is carried out to intermediate moisture content of 60÷70% conductive supply of heat energy at residual pressure 2.3÷3.2 kPa with conductive cooling of vapor condensate of removed moisture by cooling agent with temperature of minus 2÷3 °C. Then the raw material is heated to temperature of 68–70 °C in a sealed volume, held under pressure of 30–31 kPa, depressurisation is carried out to 0.70÷0.75 kPa by bubbling vapours through condensate. Additional drying till content of volatile substances is not less than 85% is carried out at residual pressure of 0.87–0.93 kPa.

EFFECT: invention increases content of vitamin C, β-carotene and pectin substances in the end product.
