摘要: 以反-对香豆酸甲酯和醛基化普鲁兰多糖为基质材料,采用浇铸-烘干法制备抗真菌薄膜。结果表明,抗真菌薄膜的透明性与反-对香豆酸甲酯的添加量呈负相关;使用万能材料试验机测试抗真菌薄膜的力学性能,发现反-对香豆酸甲酯的添加量越多,抗真菌薄膜的刚性越强而韧性越差。体外抗真菌活性试验表明,抗真菌薄膜对灰葡萄孢菌(Botrytis cinerea)具有较强的抗真菌活性,且其抗灰葡萄孢菌活性随着反-对香豆酸甲酯添加量的增加而逐渐增强。综上,抗真菌薄膜具有环境友好、成本低廉、制备工艺简单、力学性能适中、抗真菌活性强等优点,有望用于果蔬采后的保藏。

Abstract: The antifungal film was prepared by a casting-drying method using methyl trans-p-coumarate and aldehyde-modified pullulan as the matrix material. The results showed that the transparency of the antifungal film was negatively correlated with the addition amount of methyl trans-p-coumarate. Mechanical property tests using a universal material testing machine revealed that higher amounts of methyl trans-p-coumarate increased the rigidity but reduced the toughness of the antifungal film. In vitro antifungal activity tests demonstrated that the antifungal film exhibited strong inhibitory activity against Botrytis cinerea, and its efficacy gradually enhanced with increasing methyl trans-p-coumarate content. In conclusion, the antifungal film possessed advantages such as environmental friendliness, low cost, simple preparation process, moderate mechanical properties, and strong antifungal activity, showing potential for postharvest preservation of fruits and vegetables.
