Abstract
Tomato processing by-products (peels and seeds) are very rich in bioactive compounds.Therefore, the objective of this work was to increase their functional properties by applying ultraviolet B radiation (UV-B) (0, 5, and 15 kJ m-2) as a postharvest abiotic stressto study the influence on the total antioxidant capacity (TAC). TAC was assessed by DPPH, ABTS and FRAP methods during 2 days at 15ºC after treatment (0, 4, 8, 24, 28, 36, 48 h).TAC of UVB5 samples increased regarding control without UV-B treatment. In conclusion, the functionality of these samples was enhanced mainly after UV-B stress and was maintained throughout 24 h, when the extraction of the bioactive compounds in these byproducts should be performed. Thus UV-B radiation is an effective technology for the stimulation of bioactive compounds with antioxidant properties, for the benefit ofconsumers demanding a healthy diet.
