Interactive Effects of Wrapping Materials and Cold Storage Durations on Total Soluble Solids of Plum
Three wrapping materials (kraft paper + straw, kraft paper and news paper) and five cold storage durations (0, 8, 16, 24 and 32-day) were investigated for total soluble solids (TSS) of plum (cv. Shablon) during cold storage at -1°C temperature and 98% relative humidity. The experiment was laid out in Factorial Completely Randomized Design (FCRD) with four replications for each one of factors. The data collected were subjected to Analysis of Variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) at 1% probability was performed to compare the means of different treatments. The statistical results of the study indicated that although wrapping material had no significant effect (P ≤ 0.01) on TSS, cold storage duration significantly (P ≤ 0.01) affected it. Results of the study also indicated that TSS frequently decreased and increased by increasing cold storage duration. In addition, kraft paper + straw was the best wrapping materials for protecting TSS.
