dc.description.abstractStandardization of pre and postharvest treatments and nano-silver packaging was studied to increase shelf life and postharvest quality in pomegranate (Punica granatum L.) cv. Bhagwa” at the Department of Postharvest Technology, College of Horticulture, Bengaluru during the period 2015 to 2017. During the course of investigation, the effects of different pre and post-harvest treatments on various physical, physiological and biochemical parameters were evaluated. Twelve different pre-harvest chemical sprays were carried at monthly interval till harvest and fruits were stored in ambient conditions. Fruits sprayed with potassium nitrate (350 ppm), Gibberellic acid (100ppm) in combination with Benzyl adenine (75ppm) was found to maintain significantly higher amount of free radical scavenging compounds viz., ascorbic acid content, total anthocyanins content and antioxidant activities, lower peel browning and PLW with good marketable quality were recorded during storage of pomegranate fruits. Among the different postharvest treatments evaluated, methylcellulose (1%), chitosan (2%) in combination with aloe-vera gel (10%) was found superior among all the post-harvest treatments by maintaining physiological and higher retention of biochemical constituents for 25 days after storage in ambient conditions. With respect to postharvest treatment and fruits packed in nano-silver packaging and postharvest coating with methylcellulose (1%) and chitosan (2%) in combination was found the best over the other treatments in reducing the metabolic activity, biochemical changes, delaying in loss of rind moisture, browning of rind and fruits had retained significantly higher biochemical constituents (TSS, acidity, ascorbic acid, antioxidants and phenols) and marketable quality (lower loss of rind moisture, physiological loss in weight and spoilage percent) of fruits up to 64 days after harvest.en_US
