Physiology and quality of fresh-cut spinach stored in low O2 controlled atmospheres at various temperatures.

The physiology and quality of spinach (cv. Sunbest) leaves were monitored during storage in air and low-O2 controlled atmospheres (CA, 0.5, 1 and 2% O2) at 0 deg (for 28 days), 10 deg (for 9 days) and 20 deg C (for 5 days). Respiration rate and ascorbic acid loss from leaves held in air were greater at the higher storage temperatures. The low-O2 atmospheres inhibited the respiration rate of leaves stored at 10 and 20 deg . At the end of storage, ascorbic acid content was higher in leaves held in low-O2 atmospheres than in air at 10 or 20 deg . The beneficial effects of low-O2 atmospheres on reducing respiration and ascorbic acid loss were not apparent with leaves held at 0 deg . Little to no off-odour was emitted by leaves held in air or low-O2 atmospheres irrespective of storage temperature. Low-O2 atmospheres did not affect green colour retention, development of decay, or populations of aerobic mesophilic and lactic acid bacteria at any of the storage temperatures tested.
