An active coating is one of the best ways to maintain the good quality and sensory properties of fruits. A new active coating was prepared by incorporating curcumin and phloretin into the konjac glucomannan matrix (KGM-Cur-Phl). The fourier infrared spectroscopy, rheology and differential scanning calorimetry confirmed the successful fabrication of this coating. This coating showed excellent antioxidant activity revealed by the 95.03% of ABTS radicals scavenging ratio and 99.67% of DPPH radicals scavenging ratio. The result of bacteria growth curves showed that it could effectively inhibit the growth of , , and . The results of firmness, titratable acid and pH showed that it effectively prolonged the shelf life of kumquat. A novel konjac glucomannan-based active coating was provided.
活性涂层是保持水果良好品质和感官特性的最佳方法之一。通过将姜黄素和根皮素掺入魔芋葡甘聚糖基质（KGM-Cur-Phl）中制备了一种新型活性涂层。傅里叶红外光谱、流变学和差示扫描量热法证实了该涂层的成功制备。该涂层表现出优异的抗氧化活性，ABTS自由基清除率为95.03%，DPPH自由基清除率为99.67%。细菌生长曲线结果表明，它能有效抑制大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌和黑曲霉的生长。硬度、可滴定酸和pH值结果表明，它有效地延长了金橘的货架期。提供了一种新型的基于魔芋葡甘聚糖的活性涂层。
