Abstract This is the first report on a method to create a selective protective coating (i.e., “bandage”) to treat only the damaged part of pomegranate arils for shelf-life extension of these ready-to-eat chilled fruit. Implementation of a specific sequence of steps enabled the formation of an edible alginate-based protective gel layer only on the damaged surface of the aril. The consecutive steps included immersion of the arils in a solution containing a crosslinking agent, followed by immersion in an aqueous solution consisting of a polysaccharide, and then drying of the arils at ambient temperature. The selective coating method relies on the difference between the hydrophobic natural aril skin and the hydrophilic damaged parts of the aril. The formed coating was thin, transparent and sensorially undetectable, as demonstrated by triangle test. The formed coating helped preserve product quality and decreased fluid exudation during storage. The straightforward method for creating this selective coating may also be valid for any injured or cut plant tissue.

受损石榴假种皮的选择性保护涂层

摘要 这是关于创建选择性保护涂层（即“绷带”）的方法的第一份报告，该涂层仅处理石榴假种皮的受损部分，以延长这些即食冷冻水果的保质期。特定步骤顺序的实施使得能够仅在假种皮的受损表面上形成基于可食用藻酸盐的保护性凝胶层。连续的步骤包括将假种皮浸入含有交联剂的溶液中，然后浸入由多糖组成的水溶液中，然后在环境温度下干燥假种皮。选择性涂层方法依赖于疏水性天然假种皮皮肤和假种皮亲水性受损部分之间的差异。如三角形试验所证明的，形成的涂层是薄的、透明的并且感觉上检测不到。形成的涂层有助于保持产品质量并减少储存过程中的液体渗出。创建这种选择性涂层的直接方法也可能适用于任何受伤或切割的植物组织。
