    Studies on effect of post-harvest treatment on shelf life of pomegranate (punica granatum L.)
    (CCSHAU, Hisar, 2020-08) Bebe Lima Naderi; Sharma, Jeet Ram
    The experiment comprising of KMnO4 1, 1.5 and 2%, beal leaf extract 10, 20 and 30% and Aloe vera gel extract 10, 20 and 30% were conducted at Post-harvest Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar to evaluate the best and the most effective post-harvest treatment for prolonging shelf life and maintaining physicochemical characteristics of high valued pomegranate fruits cv. Bhagwa and Mridula. In this experiment, all the post-harvest treatments proved effective in increasing the shelf life and improving the physico-chemical attributes of the fruits of cv. Bhagwa and Mridula over control. However treatment with KMnO4 2% was most effective in reducing fruit firmness, specific gravity, physiological loss in weight, diseases incidence and decay loss. Different quality attributes like TSS, pH, TSS/acid ratio, anthocyanin, total sugars, reducing sugars and non-reducing sugar of fruits increased, while juice content, ascorbic acid and acidity decreased with the advancement of storage period under ambient room conditions. Among the treatments, KMnO4 2% treated pomegranate fruit had least content of TSS and sugars and significantly highest content of juice, anthocyanin, ascorbic acid and pH but had no effect on acidity of the fruits. Hence, the highest organoleptic rating was given to pomegranate fruits treated with KMnO4 2%.
