The anti-browning effect of UV-A on Golden Delicious apple slices
was also compared with other chemical treatments. As reported in
Fig. 5, L30V20 illuminator showed similar performance to AAC by decreasing
significantly (P ≤ 0.001) the color change of apple slice surface
up to 60% after 30 min irradiation (Fig. 5). Moreover the inhibitory potential
of UV-A LED treatment was stronger than 6% (w/v) AS1 commercial
formulation whose efficacy in preventing the browning of fresh-cut
fruits was demonstrated by several authors (Abbott, Saftner, Gross,
Vinyard, & Janick, 2004; Rößle, Gormley, & Butler, 2009; Toivonen,
2008).
