Abstract : The physicochemical traits and shelf life of fruits of mango cultivars Baneshan, Bangalora, Neelgoa, Neelum, Swarnarekha, Zardalu, Bombai, Hemsagar, Krishenbhog and Langra (control) during storage for 13 days at ambient conditions (33±2°C and 82±35% relative humidity) were studied. The spoilage percentage increased, whereas acidity and ascorbic acid content decreased with the increase in the storage duration. TSS [total soluble solids] and total carotenoid contents increased up to the 9th day of storage then decreased thereafter. Langra recorded the highest ascorbic acid (19.89 mg/100 g, 13th day of storage) and total carotenoid (3.41 mg/100 g, 9th day of storage) contents. Fruit spoilage started on the 7th day of storage in Neelgoa, Bombai, Krishenbhog and Langra. In the other cultivars, spoilage started on the 9th day of storage. The highest percentage of spoilage was observed in Krishenbhog (22.10%). Aspergillus, Botryodiplodia and Diplodia spp. were isolated from rotten fruits. Considering spoilage up to 12%, the longest shelf life (13 days) was recorded for Bangalora. Zardalu registered the highest respiration rate (93.0 mg CO2 kg- h-1).
