Mango is a perishable fruit with a short shelf-life once mature/harvested thus resulting in high postharvest losses. Cold storage is critical for postharvest quality preservation by delaying ripening-related changes. An experiment was carried out in Embu county of Kenya to compare the effectiveness of different storage options to preserve and extend shelf-life of mango fruits. Homogeneous mature green ‘Apple’ and ‘Kent’ mango cultivars were harvested and divided into 10 batches of 60 fruits each. The fruits were subjected to various storage conditions including Coolbot™ cold room (10±2°C, 75±20% RH), evaporative charcoal cooler (ECC) (20±5°C, 95±5% RH), zero energy brick cooler (ZEBC) (20±5°C, 90±10% RH), Wakati™ tent (25±5°C, 95±5% RH) and ambient room conditions (25±5°C, 55±15% RH). For each storage option, one batch of the fruits was packaged using Activebag® modified atmosphere packaging (MAP) and the second batch left unpackaged. The experiment was laid out in a completely randomized design with a factorial arrangement of treatments. The air and fruit pulp temperatures during storage were monitored regularly using HUATO® data loggers. Three fruits per treatment were sampled every 3 days to evaluate ripening and quality related changes including pulp temperature, colour and total soluble solids (TSS). The various storage technologies extended the shelf-life of both mango cultivars by at least 6 day and an additional 3 days when coupled with MAP. The findings reiterate the importance of cold storage and MAP in postharvest quality preservation of perishable commodities such as mango.
