Migalatiev, O.
After making tomato juice it is obtained a mixture of seeds, peels and a small amount of pulp, which represent 25-35% of the raw material mass. By the supercritical CO2 extraction the non-polar, lipid soluble compounds are extracted and it is obtained two new products: the lipophilic CO2 extract and the defatted CO2 meal from tomato wastes. The CO2 extract from tomato wastes is rich in biologically active compounds like monounsaturated (24.40 % from total) and polyunsaturated (53.20 % from total) fatty acids, antioxidants: carotenoids (84.85 mg/100g) and namely the lycopen (13.00 mg/100 g). The CO2 meal from tomato wastes is a good source of dietary fiber (25.1 %) and protein (37.6 %). Adding the extract and the meal to the typical dishes will improve the organoleptic and physiochemical characteristics and will contribute to the proper functioning of the human body.
