Abstract: Postharvest storage is important for any system of fruit commercialization. This work was carried out to study the influence of two temperatures (80C and 120C), and two packaging types (unpacked was the control, perforated and not perforated polyethylene packaging) on the blackheart of pineapples (Ananas comosus (L) Merr.) cv. Smooth Cayenne. A higher number of fruit were affected by endogenous darkening at 80C. The incidence of this disorder was more rapid and with higher intensity at 80C than 120C. In both temperatures, the unpacked fruit were more affected by this injury, while the fruit kept in not perforated polyethylene showed less darkening. There was an increase in soluble solids, total acidity and fresh weight loss as the endogenous darkening increased, and a decrease in flesh firmness and pH. The pH was higher and the total acidity was lower in the unpacked fruits. Firmness declined during cold storage and showed a high influence of the packaging type.
