Effect of post-harvest treatments on quality attributes like total soluble solids, total sugar and reducing sugar of langra mangoes (Mangifera indica L.) during storage

Abstract

The effect of calcium salts (calcium nitrate and calcium chloride) and Gibberellic acid on quality attributes and consumer’s acceptability of Langra mangoes during storage was examined. The fruits were treated with Ca(NO3)2 at the concentration of 1, 2 and 3 per cent, CaCl2 at the concentration of 1, 2 and 3 per cent and GA3 at the concentration of 50, 100 and 150 ppm. Water treated fruits were taken as control. Data were recorded in respect of TSS, reducing sugars and total sugars under influence of these treatments. All treatments were found effective in maintaining the higher level of these quality attributes of fruits during entire course of the experiment. At end of trial, Ca(NO3)2 at 2% was proved as the best treatment in respect of TSS, reducing sugars and total sugars and was able to maintain the level of these up to 24.32%, 9.00% and 20.05% respectively.
