Characteristics of Squid (Illex illecebrosus LeSueur) Fillets Dried Using a Combination of Heat Pump Drying and Far Infrared Radiation

摘要: Squid ( Illex illecebrosus LeSueur) fillets were dried using a heat pump (HP) dryer combined with far infrared radiation (FIR) at 500, 1000 and 2000 W. Squids an initial moisture content of 83.73 ± 0.39% (w.b.) to about 17% 50 °C air flow rate 0.8 m s-1. The drying data fitted 11 thin-layer models, among which the Page model gave better predictions than others. effective diffusivity calculated from second Fick’s law increased 0.53 × 10-10 1.33 m2 s-1, increase in FIR intensity, suggested that contributed loss thus decreased time. Changes hardness color power supplied FIR. No significant differences shrinkage found for all samples. HP + 500 W highest rehydration compared other methods.
