Figures 9 and 10 show the measured results of color of dried shrimp with 1- stage and 2-stage drying strategies. The experimental results for all drying conditions concluded that in case of drying with 1 stage and 2 stage strategies, higher drying temperatures tended to decrease the total color difference of samples ( Δ E), dried shrimp with combined infrared heat radiation and hot air convection significantly enhance the redness value (Hunter a-value) of the shrimp. However, from Figures 9 and 10, the brightness value (Hunter L-value) of dried shrimp with 1-stage hot air drying was higher than that found when combined infrared heat radiation and hot air convection were used.
