Weight loss considered one of the main causes of quality loss in pomegranate fruits during chain marketing. Therefore, this study was conducted on Manfalouty pomegranate (Punica granatum L.) in a private orchard in El Badary, Assiut Governorate, Egypt in 2017 and 2018 to define the various causes of losses during chain handing and estimate it. The fruits harvested at three periods early (September) mid (October) and late season (November). The total losses at harvest were 5.94%, 9.30% and 23.50% for early, mid and late season, respectively. The main cause of losses is due to cracked and infected pests. The total loss of fruits during chain marketing was highest in retail market in comparison with wholesale during early, mid and late season. The main causes of losses due to weight loss and shrinkage fruits. According to data dealing with storage pomegranate fruits at 5±1°C and relative humidity 85-90%, the highest fruit losses found in the third month and this losses due to fruit weight loss and internal chilling injury (brown discoloration) so the storage life of fruit should be two months.
