Effects of variety and different coating treatments on postharvest quality and shelf life extension of banana

Abstract

An experiment was carried out at the Laboratory of Department of Horticulture, Bangladesh Agricultural University, Mymensingh during September to October 2019 to study the effect of different coating treatments on shelf-life and postharvest quality of banana. The experiment comprised of two banana varieties viz. V1: Mehersagar and V2: Amritsagar and nine coating treatments viz. T1: Control (Untreated), T2: GA3 (100 ppm) + Carboxymethyl cellulose (CMC) 1 %, T3: Calcium gluconate, T4: Soybean oil, T5: Garlic extract, T6: Neem extract, T7: Turmeric powder, T8: Lemon extract and T9: Moringa leaf extract (5%) + 1% CMC. The two-factor experiment was laid out in completely randomized design with three replications. The data on various parameters were statistically analyzed. Results revealed that between two varieties, V2 (Amritsagar) showed the longer shelf life (11.66 days) than V1 (Mehersagar) (9.89 days). Among the different coating treatments, T7 (Turmeric powder) treatment showed the best performance (14 days) in shelf life extension as compared to control. In combined effect, V2 (Amritsagar) with T7 (Turmeric powder) treatment (V2T7) gave the superior result (15.0 days). This combination also caused the lowest total weight loss (9.42%), the highest moisture content (82.59%), TSS (23.67%), and pulp to peel ratio (3.20) during the period of investigation.
