This study was conducted on the interactive effects of Coating Methods (CM) and Storage Periods (SP) on Nantes carrot during ambient storage at temperature of 25°C and 65% relative humidity. Four CM [Carboxy Methyl Cellulose + Cellophane Film (CMC + CF), Carboxy Methyl Cellulose (CMC), Cellophane Film (CF) and No-Coating (NC)] and five SP (0, 4, 8, 11 and 14-days) were investigated for some qualitative characteristics including water content, total soluble solids (TSS), reducing sugar and firmness. A factorial experiment design was laid out in completely randomized design with 3 replications for each one of factors and Duncan's multiple range tests were performed to compare the means of different treatments. The statistical results of the study indicated that CM and SP significantly (P < or = 0.01) affected all traits. Interaction of CM x SP for all traits was also significant. The statistical results of the study indicated that CMC + CF for water content and reducing sugar, and CF for firmness were the best CM. In addition, water content, reducing sugar and firmness decreased by increasing the SP, whereas TSS increased by an increase in SP.
