Intermittent warming effects on postharvest cold storage of 'Fortune' mandarins.

ABSTRACT :

 

Fortune mandarins were harvested in the middle of March and stored for 2 months in cold rooms. Control fruits were kept at constant temperature (6 deg C), and the others were exposed to cycles of low and high temperatures (5 and 2 days, respectively). The effectiveness of 3 intermittent warming sequences was evaluated: 0/12 deg , 2/10 deg , and 4/8 deg . A 95% RH was used. As an additional shelf-life treatment, at monthly intervals, fruits were kept at 20 deg and 75% RH for 10 days. Intermittent warming at 0/12 deg or 2/10 deg greatly reduced chilling injury (CI). Weight loss (WL) was slightly higher in fruits exposed to intermittent warming than in the control, and mould decay was very low in all cases. Loss of quality was observed in fruits subjected to intermittent warming at 4/8 deg , while fruits held at 0/12 deg showed high quality and good appearance during the storage period. The quality of mandarins stored at 2/10 deg was good during the 1st month of storage, but decreased afterwards.
