• The phenolic compounds from natural plant extracts, which have strong antioxidant properties as inhibitors for browning retardants of fruits, have been extensively investigate in the last few decades. In this study, the polyphenols in Cleistocalyx operculatus (Roxb.), a distinct plant in tropical region, was successfully extracted and determined. The obtained Roxb. extract (CE) as an antioxidant additive was employed in Chitosan/Gum Arabic (CH/GA) edible coating for the fruit preservation. The resultant CE/CH/GA coating revealed the high effectiveness in improving the freshness of banana at ambient storage conditions. The properties of bananas before and after coated by CE/CH/GA were investigated and assessed. The surface structure of banana was examined by using scanning electron microscopy, showed wrinkle and crack structure for uncoated banana and smooth surface for banana coated with CE/CH/GA coating. The freshness of banana treated with CH/GA/CE edible coating could last for 21 days of storage at room conditions. Thus, it is promising for good potential practical application to preserve fruits. •Successful extraction of the natural polyphenols from C. operculatus plants•High total polyphenol content and high antioxidant property of C. operculatus extract•Successful fabrication of new edible coatings of Chitosan/Gum Arabic/C. operculatus extract•Significant improvement of banana shelf-life with the new, edible coating composite
