Effects of coating methods and storage periods on some quality characteristics of carrot during ambient storage

Abstract

This study was conducted on the 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 quality characteristics including water content, total soluble solids (TSS), reducing sugars and firmness. The statistical results of the study indicated that CM and SP significantly (P 0.01) affected all traits. Interaction of CM × SP for all traits was also significant. The statistical results of the study indicated that CMC + CF for water content and reducing sugars, and CF for firmness were the best CM. In addition, water content, reducing sugars and firmness decreased by increasing the SP, whereas TSS increased by an increase in SP.
