The E increased with removing moisture from samples and reached to a quasiequilibrium state toward the end of dry-ing process. The primary increment of E might be attributed to the both carotenoid concentration and classic Maillard reaction at the beginning of drying process as results ofproducts shrinkage and higher amount of water content,respectively. However, toward the end of drying process and evaporation of the major part of moisture content, the rate of these reactions and their effects on product appearance were dramatically decreased.
