Convective Drying Kinetics and Physical Properties of Silver Carp (Hypophthalmichthys molitrix) Fillets

摘要

The aim of this work was to investigate drying kinetics of silver carp fillets at the temperatures of 40, 50, 60, and 70°C for two air velocities (0.5 and 1.5 m/s) and to evaluate the effect of drying temperature on the physical properties of the products. From regression analysis of the experimental data, a Two-term model was found to adequately predict the drying process at all conditions tested. Effective moisture diffusivities (D_eff) ranged between 2.47 × 10−10 m2/s and 5.98 × 10−10m2/s and increased with temperature and air velocity. Rehydration ratio, hardness, and springiness were significantly affected by drying temperature. Color parameters, except b*, showed no dependence on temperature.View full textDownload full textKeywordssilver carp fillets, convective drying, mathematical modeling, effective moisture diffusivity, rehydration ratio, color, textureRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10498850.2011.575536
