© The Author(s) 2019.Faba beans have a short shelf life which is even reduced after fresh-cut processing mainly due to browning and dehydration. In that sense, the effects of a UV-C treatment (3 kJ m¿2), compared with non-exposed beans (CTRL), were studied on the sensory and microbial quality, and bioactive and anti-nutritional content of fresh-cut faba beans (cv. Muchamiel) during storage at 5 ¿. The effect of a domestic microwaving (3 min, 900 W) on bioactive and anti-nutritional compounds of fresh seeds prior to consumption at each sampling time was also studied. UV-C treatment extended the fresh-cut faba bean shelf life from 7 to 10 days with browning score (the main sensory parameter adversely affected) of 8 and 1 log unit lower than CTRL at day 10. UV-C did not negatively affect the total antioxidant capacity of samples during storage. The phytic acid and raffinose contents decreased by 30/40%, respectively, after 10 days, without influence of the UV-C treatment. Microwaving reduced the phytic acid and condensed tannins contents by 30% in those samples stored for up to six days, with low microwaving effect in the last storage days. Nevertheless, UV-C improved the condensed tannins reductions through storage (¿30%) compared with non-irradiated samples.
