METHOD FOR PRODUCTION OF MIXTURE OF TOMATOES, CARROTS AND CELERY FOOD POWDERS Russian patent published in 2015 - IPC A23B7/02 A23B7/15 C09B61/00 

FIELD: food industry.

SUBSTANCE: vegetal raw materials are represented by tomatoes, carrots and celery. Tomatoes are cut into 5-8 cm thick slices, put in 1 layer onto a screen tray and dried with infrared rays during 150-180 minutes. Carrots and celery are cut into bars with 7×7 mm section, separately put in 1 layer with thickness equal to 10-15 mm onto a screen tray and subjected to infrared drying during 120-150 minutes. Infrared drying in performed in the "heating-cooling" pulse mode, specific energy flux density amounting to12-15 kW/m ² and wavelength band equal to1.2-2.4 mcm until the limit temperature 55-65°C is reached. Resulting from such treatment, the tomatoes and carrots moisture content is reduced to 6-8%. Then infrared-dried tomatoes, carrots and celery are milled into particles sized 146 mcm (on the average) in the flow-type roll planetary mill; the powders are mixed at the following ratio: 80% of tomato powder, 11.5% of carrot powder, 8.5% of celery powder.

EFFECT: vegetal raw material powders mixture has high nutritive value and increased organoleptic properties.
