Electrical conductivity was investigated in relation to percent pared fruit or damage indexes prepared by manually paring strawberries and stimulating bruising with a 3‐dimensional vibrator. The conductivity was associated with the percent pared fruit (0 to 40%) or damage indexes (1 to 5) of strawberries, with correlation coefficients of 0.938 and 0.917 at P < 0.05, respectively. Furthermore, the bruising caused by the 3‐dimensional vibrator resulted in increases in electrical conductivity in response to vibrating time and vibrating force. The decrease in electrical conductivity of strawberries treated with the vibrator during 2 d of storage at 25 °C and 80% relative humidity may be due to wound healing of the fruit. Electrical conductivity exhibited potential for quantitatively evaluating damage of strawberries during transportation and marketing.
