Description: Prunes, which are commercially produced by dehydrating plums are considered to be a prominent source of health promoting nutraceutical compounds including phenolics, flavonoids, and vitamins. Conversion of plums into prunes using dehydration process is a critical part of their postharvest handling. Producers and processors of a novel variety named Yellow skinned European Plums (YEPs) in Ontario, Canada are facing a major problem of browning caused by thermal degradation of sugars during conventional hot-air dehydration process, which results in commercially less appealing brown prunes. However, pre-treating YEPs with chemicals including, ascorbic acid, citric acid and potassium meta-bi-sulphite can reduce browning of YEPs and improve the overall efficiency of the dehydration process. Hence, in this study optimization of conventional hot-air and advance freeze dehydration processes with and without chemical pre-treatment of YEPs was undertaken to produce commercializable dried golden prunes.
