Aiming to evaluate techniques for modified atmosphere and application of sulphur anhydride upon parameters of quality of postharvest on blueberry fruit (Vaccinium corymbosum L.) cv. Emerald, an experiment of six treatments was conducted, given by the combination of two factors, modified atmosphere (with and without) and different concentrations of sulphur dioxide (generated by 0, 1 and 2 g of sodium metabisulphite) during 7, 14, 21 and 28 days at 0 °C. The dose of 2 g of modified atmosphere sodium metabisulphite showed no rotting, in contrast to the control treatment that showed a 4.86% after 28 days of storage. The results indicate that grey rot incidence decreased significantly (p ≤ 0.05) with sulfur dioxide in modified atmosphere bag, with an effect of interaction between both factors, however the gas that caused whitening damage on fruits, which corresponded to 11.66% with a dose ...
