Effect of 1-Methylcyclopropene and Polyhexamethylene Guanidine on Postharvest Quality of Banana (Musa paradisiaca) cv. Yelakki
Year: 2017
Type: article
Abstract: A study was undertaken to manage two factors that are responsible for reduced market value in banana cv. Yelakki namely ethylene biosynthesis and microbial deterioration. Freshly harvested stage 2 banana fruits treated with chemicals, 1-methylcyclopropene (1-MCP) and poly hexa methylene guanidine (PHMG) at different concentrations and stored in corrugated fiber board boxes at ambient condition for 15 days. The fruits treated with combination of 1-MCP (20 ppm) and PHMG (2.0%) showed lower fruit respiration rate (0.02-0.15mg CO2 kg-1 h-1), lower PLW (3.89-18.83%) and low decay loss (16.54%). This treatment was also found to have components such as chlorophyll content, firmness, ascorbic acid, total soluble solids, total sugars and pectin, mineral contents viz. calcium, magnesium and potassium on higher side at the end of 15 days storage. Regression studies of the experiment showed a positive and significant association with ripening rate (0.43), colour change (0.56), PLW (0.85), moisture (0.16), TSS (0.49), total sugars (0.62), pectin (0.43), calcium (0.35), potassium (0.29) and decay loss (0.64) and it was negative for firmness (-0.29) and ascorbic acid (-0.15). The treated fruits showed significantly higher shelf life of 15 days however, the scores of sensory analysis viz. colour, taste, texture, flavor and overall acceptability were poor.
