METHOD FOR OBTAINING CAROTENOID CONCENTRATE FROM TOMATO POMACE Russian patent published in 2024 - IPC A23L5/44 A23L33/00 C09B61/00 

FIELD: food industry.

SUBSTANCE: used to obtain carotenoid concentrate from tomato pomace used in food production. A method has been proposed for obtaining a concentrate of carotenoids from tomato pomace, which includes processing tomato pomace in an electromagnetic microwave field, drying the processed tomato pomace in the IR radiation zone, grinding and processing the crushed dried tomato pomace with an enzyme solution containing cellulase, xinalase, protease and pectinase in an amount providing 150, 100, 50 and 100 units of activity per 1 g of dry matter of crushed dried tomato pomace, respectively, separation of the sediment from the resulting fermented mass by filtering under vacuum, heating the sediment to inactivate enzymes and drying under vacuum, subsequent extraction of carotenoids from the dried sediment with acetone, filtering the resulting extract under vacuum and removing acetone from the extract under vacuum, while treatment with an enzyme solution is carried out at a temperature of 45-50°C and the ratio of crushed dried tomato pomace: enzyme solution equal to (1:10)÷(1:12), for 1.5-2.0 hours with constant stirring, and the extraction of carotenoids from the dried sediment with acetone is carried out in one stage at a temperature of 40-45°C and the ratio of crushed dried tomato pomace: acetone w/v equal to (1:14)÷(1:15), for 8-10 minutes in the ultrasonic influence zone with a specific power of 0.2-0.4 W/cm³ and for 40-45 minutes with constant stirring.

EFFECT: obtaining a concentrate of carotenoids with a high content of lycopene - 721-739 mg/100 g and beta-carotene - 516-520 mg/100 g, and also reducing the overall duration of the production process.
