Abstract

The success in the effort of developing and distributing Tejakula tangerines is influenced by various factors, one of which is the accuracy of postharvest handling. This is because with proper postharvest handling, the quality of oranges can be maintained and production losses can be reduced. This study aims to determine the storage duration and the most suitable concentration of edible coating to maintain the physical and chemical properties of oranges during storage. This research was arranged based on a Randomized Complete Block Design with a split plot design using two factors and three replications. The main factor is the storage duration with five levels, namely 0 days (L0), 7 days (L1), 14 days (L2), 21 days (L3), and 28 days (L4). The additional factor is the application of edible coating made from sweet potato starch with four levels of concentration, namely without edible coating application (E0), 1.5% concentration (E1), 3% concentration (E2), and 4.5% concentration (E3). The results showed that the storage duration and different concentrations of edible coating had a significant effect on the physicochemical properties of the fruit except for sensory tests of taste, texture, and likability. There was a significant interaction on the physicochemical properties of the oranges in almost all variables except for hardness, moisture content, and Total Soluble Solids with the lowest weight loss at L1E2
