Abstract

A sustainable solution to prevent the waste of fruits and vegetables from spoilage is the use of edible coatings or films. This research project aimed to create a fresh coating recipe that could effectively extend the shelf life of mangoes. The coating was composed of chitosan, glycerol, and gum Arabic mixed with the extract obtained from the extraction of Cleistocalyx operculatus plant. The prepared exact has a total polyphenol content of 17% and showed potent free radical scavenging abilities in a dose-dependent manner. The chitosan/gum Arabic/Glycerol/extract edible coatings were analyzed using SEM and FTIR spectroscopy, revealing a smooth and uniform coating with a well-integration of components. Coating the mangoes with this formulation resulted in significant improvements in their appearance, brightness, weight loss, firmness, titratable acidity, and CO₂ respiration rate compared to uncoated samples. The optimal concentration of the extract in the coating was determined to be 0.25% w/w for the best protective performance. After 21-day storage at room temperature, uncoated mangoes were found to be rotten, while coated mangoes remained fresh.

通过自然保存提高芒果的保质期：研究多糖可食用涂层和叶片提取物的功效。

防止水果和蔬菜变质浪费的可持续解决方案是使用可食用涂层或薄膜。本研究项目旨在创造一种可以有效延长芒果保质期的新鲜涂层配方。以壳聚糖、甘油和阿拉伯胶为主要原料，并以闭锁花提取液为主要原料，制备了该涂层。制备的提取物总多酚含量为17%，并表现出强自由基清除能力，且呈剂量依赖性。利用扫描电镜和红外光谱对壳聚糖/阿拉伯胶/甘油/萃取物可食用涂层进行了分析，发现涂层表面光滑均匀，各组分结合良好。与未涂覆的样品相比，用这种配方涂覆的芒果在外观、亮度、重量减轻、硬度、可滴定酸度和二氧化碳呼吸速率方面都有显著改善。结果表明，涂层中提取液的最佳浓度为0.25% w/w，保护效果最佳。室温保存21天后，未包衣芒果腐烂，而包衣芒果仍保持新鲜。
