Abstract: Intermittent warming (IW) cycles slow down the physiology of fresh horticultural commodities, thereby extending their storage life. We investigated the effects of IW on physiological disorders, physicochemical, sensory parameters and the emission of volatile organic compounds (VOCs) of pomegranate (Punica granatum; cv. Wonderful) fruit during a 3-month cold storage period. Pomegranate fruit batches were subjected to IW cycles of 3d at 5°C, followed by 1 d at 20°C (IW 3d) and 6 d at 5°C, followed by 1 d at 20°C (IW 6d). During cold storage at 5°C, fruit samples were transferred to shelf-life conditions at 20°C for 4 d before analysis was performed monthly. Continuous fruit mass loss was observed across all treatments during storage but was highest (p
