The term mango skin browning covers a range of postharvest blemishes affecting mango fruits. Skin browning is a major fruit quality problem, causing the downgrading of produce on Australian markets. Etching and lenticel spotting are 2 of the more prevalent forms of browning. Etching consists of numerous small dark flecks, and lenticel spotting consists of a dark halo of tissue around lenticels. During 1994-95, the components of the harvesting and postharvest handling operations which contributed most to these blemishes were investigated on several Australian farms. Detergent/desapping and hot dips contributed most to etching and lenticel spotting. In the laboratory, detergent used at commercial rates caused etching and lenticel spotting. Etching appeared to be caused by the aided entry of aqueous solutions into the epidermis and underlying cells through small fissures in the cuticle. These fissures usually occur in the centre of cuticular platelets as they subdivide or at the junctions between p

latelets. It is concluded that detergents have a major role in lenticel spotting and forms of browning.
