Momordica charantia polysaccharide (MCP) has been repeatedly reported due to its anti-diabetic properties. Up to our knowledge, no research has discussed the use of MCP as a nanofiber matrix in an active food packaging. As an antibacterial and anti-oxidant agent, phlorotannin (PT) was encapsulated in MCP nanofibers to promote these activities. Nanofiber membranes were treated with cold plasma to increase their application performance. Antioxidant and antibacterial activities of PT and MCP against Escherichia coli O157:H7 were individually evaluated. The prepared nanofibers were assessed for their physical and mechanical properties in order to select the better-characterized ones. The successfulness of PT loading into MCP nanofibers was confirmed using SEM, AFM, TGA and DSC. After cold plasma treatment, the release efficiency of PT from the nanofibers was enhanced by 23.5 % (4 °C) and 25 % (25 °C), respectively. Correspondingly, both antibacterial and anti-oxidant activities of PT/MCP nanofibers were markedly improved.

冷血浆处理过的芦丁单宁/苦瓜多糖纳米纤维，用于活性食品包装。

苦瓜多糖（MCP）由于其抗糖尿病特性而被反复报道。据我们所知，尚无研究讨论将MCP用作活性食品包装中的纳米纤维基质。phrotrotannin（PT）作为一种抗菌和抗氧化剂被封装在MCP纳米纤维中，以促进这些活性。用冷等离子体处理纳米纤维膜以增加其应用性能。分别评估了PT和MCP对大肠杆菌O157：H7的抗氧化和抗菌活性。评估所制备的纳米纤维的物理和机械性能，以选择性能更好的纳米纤维。使用SEM，AFM，TGA和DSC证实了PT加载到MCP纳米纤维中的成功。冷等离子体处理后 PT从纳米纤维的释放效率分别提高了23.5％（4°C）和25％（25°C）。相应地，PT / MCP纳米纤维的抗菌和抗氧化活性都得到了显着提高。
