A late maturing (End Aug to Mid Sept) Pakistani mango cv. Sufaid Chaunsa has high export potential, particularly in neighboring markets of Iran and China. However, market access is conditional with hot water (HW) phytosanitary treatment protocol for disinfestation of fruit fly as agreed with both countries (Iran: HW dip at 45°C for 75 min; China: HW dip at 48°C for 60 min). Objectives of present studies were to evaluate the effect of obligatory market access protocols on Sufaid Chaunsa mangoes; and to optimize storage temperature (10 & 12°C) under the prospective of shipping the treated mangoes to these countries. For this purpose, uniform mature mangoes were subjected to hot water treatment (HWT) at 45 and 48°C for 75 and 60 min, respectively. Some more fruit were also subjected to HWT of 48°C for 60 min with additional dip of hot carbendazim (40 g/100 L) at 52°C for 5 min. Non-treated fruit were considered as control. Treated fruit were divided into two equal lots and stored at 10 and 12°C (80-85% RH). During storage, fruit peel color and softness were recorded on 21, 27 and 32 days, while disease development, physico-chemical and organoleptic characteristics were assessed at ripe stage. Fruit subjected to HWT (48°C for 60 min) with additional treatment of hot carbendazim (40 g/100 L) at 52°C for 5 min were more firm and had higher levels of total sugars as compared to the fruit of other treatments. Higher fruit peel color development score (after 21, 27 & 32 days of storage) and higher total carotenoid levels (at ripe stage) were recorded in fruit stored at 12°C, irrespective of HW treatment effect. Higher titratable acidity was recorded in fruit subjected to HWT at 45°C for 75 min at 10°C storage. Among organolaptic characteristics, better pulp color score with better taste, texture and aroma was recorded in fruit stored at 10°C by the taste panel. HW treated fruit showed lesser anthracnose incidence as compared to fruit with no treatment. In conclusion, HW phytosanitary protocols for export of mango to Iran and China had no negative effect on fruit quality attributes of cv. Sufaid Chaunsa; and 10°C was found as the better shipping temperature. However, control of diseases especially stem end rot is critical and aroma volatile production warrants further research for successful sea shipments for export of this cultivar.
