Abstract
The effect of 1-methylcyclopropene (1-MCP) treatments and storage conditions in the regulation of the physicochemical and bioactive properties of mango fruits (Mangifera indica L. cv. BARI-4) were investigated during storage. Different concentrations of 1-MCP treated samples (T0 = Control, T1 = 0.5 μL/L, T2 = 1.0 μL/L, T3 = 1.5 μL/L, and T4 = 2.0 μL/L) were stored in developed storage structure (10±1 °C and 90 % RH), cold storage (3 ± 1 °C and 80 ± 2 % RH), and ambient storage (29 ± 3 °C and 65 ± 2 % RH). The change in fruit quality including weight loss, firmness, surface color, storage life, chemical, and bioactive properties were studied periodically at 10, 20, 30 and 40 days of storage. The results demonstrated that 1-MCP treatment effectively maintained the quality of fruits by retarding the loss of weight, firmness, total soluble solids (TSS), and titratable acidity, which were served as a quality parameter during storage. The 1-MCP treatment dramatically delayed the change in color, quality measures, and bioactive properties compared to the control group. The storage condition greatly influenced the postharvest quality value and storage life. In combination with the developed storage structure and 1-MCP treatment preserved the acceptability of fruits to a great extent for around 40 days. The T2 = 1.0 μL/L 1-MCP treatment preserved the fruit quality for the highest days of storage 14, 34, and 46 days in ambient storage, cold storage, and develop storage structure respectively. The developed storage structure (10 ± 1 °C and 90 % RH) with 1-MCP (1.0 μL/L) treatment suggested the optimum storage ability for preserving the postharvest storage life of mango fruits. By implementing these findings mango growers and suppliers can reduce post-harvest losses, expand market reach, and provide consumers with high-quality mangoes that retain their quality for an extended period.
