Reductions in flesh discolouration and internal morphological changes in Nanhui peaches (Prunus persica (L.) Batsch, cv. Nanhui) by electrolysed water and 1-methylcyclopropene treatment during refrigerated storage

► We develop a novel preserving method to reduce flesh discolouration of Nanhui peaches. ► Biochemical and physiological responses related to discolouring flesh were evaluated. ► The internal morphological changes in Nanhui peaches were monitored using MRI. ► EW/MCP treatment can suppress flesh discolouration of Nanhui peaches during storage. ► MRI is an effective method to inspect flesh discolouration of Nanhui peaches.
