STABILISED PECTIN-CONTAINING PUMPKIN PULP PRODUCTION METHOD Russian patent published in 2015 - IPC A23L1/212 A23N4/00 A23N15/00 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. According to the method, fruits are washed (with washed fruits stalks removed), crushed to separate seeds, pumpkin pieces are milled with the help of a grinder; juice is separated from the produced squash with the help of a double-screw press until the produced pulp moisture content is 75-82%. Then the squash is washed to remove water-soluble ballast compounds, pigments and metal inclusions during 15-45 min at 40-50°C by way of stirring a mixture of pulp with purified water at a ratio of at least 4:1, the stirring rate being 40-43 rpm, in a vessel equipped with a heating system. Then the produced suspension is separated into a liquid and a solid phases with the help of a vacuum drum filter; the mass remaining on the filter fabric is squeezed out with the help of a double-screw press. The washing and separation operations are repeated 2-8 times. Then one performs staged drying. At the first stage, the mass is dried according to a counter-flow cross scheme in a rotor drum dryer until production of a product with residual moisture content equal to 30-32%. The heat transfer medium is represented by air heated to 150-180°C. At the second stage, the pulp s additionally dried in a vacuum dryer at a temperature of 55-60°C till residual moisture content is equal to 6-10%.

EFFECT: invention allows to reduce pumpkin pulp production time, enhance the pulp consumer properties and extend its storage life.
