To improve the drying rate and to reduce the energy consumption of aquatic product, scallop muscle were treated with high pulse electric field (HPEF) in different frequency, and different voltage. The hot air drying rate of treated scallop muscle was determined, meanwhile, several quality parameters such as the shrinkage and rehydration rate of samples with pretreatment were determined to compare with those of untreated samples. The results indicated that the drying rate of scallop muscle can be improved by HPEF pretreatment without affecting the quality, and 22.5kV for pretreatment voltage and 50Hz for pretreatment frequency is the optimum treated parameters.
