Nanocoating-konjac application as postharvest handling to extend the shelf life of Siamese oranges

Siamese orange fruit is very popular today, driven by the increasing public demand or healthy food. oranges contain bioactive phenolic compounds, carotenoids, vitamins, minerals, and fiber which are good for health. The weakness of their quality declines quickly short shelf life. Postharvest handling with application coatings from natural ingredients to extend life fruits currently needed reduce use synthetic materials. Natural that have potential be used as base materials konjac tubers because they glucomannan polysaccharides compounds can form coatings. purpose this study was determine effect nanocoating-konjacon oranges. research began preparation nanocoating-konjac formula main ingredient nanocoating nano coating-konjac on surface This a completely randomized two-factor design, namely (without coating, nanocoating) storage time (0, 5, 10, 15 days), three replications. Variables observed: Weight loss, number damaged fruits, color, texture, acidity, total soluble solids, water content, vitamin C, plate count. data obtained tested diversity SPSS, if it shows differences test continued Duncan's Multiple Range Test. conclusion nanocoating-konjac, without coating weight dissolved count during storage. recommends postharvest until 10th days.
