This may beascribed to the fact that tomatoes have high titratable acidity andphenolic content, which can stabilize ascorbic acid (Mapson, 1970;Miller and Rice Evans, 1997). Similarly, an observation of stableascorbic acid content during postharvest storage of strawberriesand blueberries was also reported (Kalt et al., 1999). Although nosignificant improvement of pressure treatment on ascorbic acidin tomatoes was observed, the extension of shelf-life by storingtomato under pressure could eventually provide a higher value ofascorbic acid when compared to conventional commercial tomatostorage (13◦C)
