Abstract
Several companies worldwide are interested in carrying out the industrial extraction of carotenoids (lycopene, beta-carotene and others) from tomato wastes (peels and seeds) in order to meet the requirements of the international nutraceutical (food additives), pharmaceutical and cosmetic markets.
This project investigated the theoretical capacity of a large area in Northern Italy with many tomato processing factories, to obtain carotenoids from tomato solid wastes and the possibility of reducing the degradation of these pigments via isomerization and oxidation under different processing conditions.
The wastes collected from 16 tomato processing factories operating in the Pianura Padana area were analysed and stabilized with different pre-treatments in order to improve the yield of the subsequent extraction process (CO2 SFE).
