Effect of High Pulsed Electric Field Pretreatment on Hot Air Drying Rate of Sea Cucumber

Abstract:

In order to improve the drying rate and to reduce the energy consumption of aquatic product, sea cucumber were treated with high pulse electric field (HPEF) in different frequency, and different voltage. The hot air drying rate of treated sea cucumber was determined and, 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 hot air drying rate and rehydration rate of sea cucumber can be improved and the shrinkage of sea cucumber can be decreased by HPEF pretreatment, and while HPEF pretreatment was applied for 22.5kV at a frequency of 70Hz, the drying rate could be increased approximately 58%.
