Vapor Treatments, Chilling, Storage, and Antioxidants in Pomegranates (original) (raw)

Elsevier eBooks, 2015

Abstract

Abstract Pomegranate ( Punica granatum L.) is rich in bioactive compounds such as phenolics and anthocyanins with proven antioxidant activity in vitro and in vivo . However, pomegranates are considered as perishable commodities with severe storability problems due to their sensitivity to developing chilling injury symptoms when they are stored at low temperatures. These symptoms are manifested by skin browning, surface pitting and desiccation and accompanied by increases in electrolyte leakage leading to quality losses and reduced shelf-life. In this chapter, an overview of the chilling injury incidence and its possible minimization throughout appropriate post-harvest treatments is provided, with special emphasis on some innovative tools such as the natural compounds methyl jasmonate and methyl salicylate. These treatments reduced chilling injury and enhanced the content of bioactive compounds and the total antioxidant activity of the arils along storage leading to fruit with enhanced phytochemicals and increased health-beneficial properties to consumers.
