• An effort was made to elongate the shelf life of strawberries by the application of an alternating current (60 Hz) high electric field (HEF). An internal voltage as high as 174 V was measured in a strawberry by applying a 430 kV/m external electric field. Short treatment periods (0.5-1.5 h) with the HEF (430 kV/m) was found to reduce rotting (%) of the strawberries, but continuous HEF treatment was more effective to control rotting. Because continuous HEF treatment without packaging caused excessive weight loss, the strawberries were packed in polyethylene trays (OPS, P-11) and covered without sealing. The HEF was then continuously applied to the strawberries. Strawberries treated by continuous HEF for 6 days at 20°C and by electric fields of 0, 114, 172, 285 and 430 kV/m resulted in 80, 60, 50, 30 and 0% rotted samples, respectively. No differences were observed in surface color, pH, acidity and sugar contents between treated and non-treated samples.
