vitamin C content decreased over 12 days storage time at 4 °C in treated and control apple
slices, however pretreatments with ascorbic acid and hot water maintained higher vitamin C content at end of
storage. Sapers (1993) reported that once the ascorbic acid has been oxidized to dehydroascorbic acid,
quinones can again accumulate and undergo browning, therefore, these treatments may reduce fresh cut
browning by maintaining higher vitamin C. Previous reports showed that the individual effect of ascorbic acid is
temporary, other alternatives should be searched to control browning (Rojas-Grau et al., 2008).
