Abstract : A hypobaric storage system was developed to evaluate the storage life of mangoes under tropical conditions. The effects of temperature, pressure, precooling and waxing on the ripening and quality of mangoes were evaluated based on fruit firmness, total soluble solids, weight loss, decay, chlorophyll content and skin colour change. Low pressure storage at 100 or 60 mm Hg at 13°C was most effective and extended the storage life of mangoes to 4 weeks. Wax treatment maintained chlorophyll levels for up to 20 days but high concentrations injured the skin after 20 days of storage. Mangoes precooled to 15° and treated with a low wax concentration (0.5%) could be kept for up to 30 days in storage without loss in quality after ripening.
