Abstract

Nanofibrous zein/PEG based membranes incorporated with natural antimicrobial compounds were fabricated by electrospinning method. Structural and thermal analysis of prepared nanofibers revealed that the applied processing technique did not significantly affect the structure of pristine zein polymer. Morphological characterization showed a higher degree of polydispersity in the fibers modified with eugenol, thymol, nisin, or their combinations, and an average fiber diameter in the range from 300 to 390 nm. Nanofibrous samples with eugenol and thymol prevented the growth of Escherichia coli and Staphylococcus aureus, while the nisin or its mixtures with phenols proved a high antibacterial effect against Gram-positive Listeria ivanovii. Zein/PEG membranes with bioactive molecules significantly eliminated biofilm formation, with the most pronounced effect of zein/PEG/Eug/Thy combination. Biodegradability testing of bioactive membranes revealed no significant slowdown of degradation process in comparison to control sample. Zein/PEG hydrophilic nanofibers enriched with phenol/nisin combinations demonstrated a high potential for development of sustainable packaging to improve the shelf-life and quality of foods.

加入天然抗菌化合物的可生物降解 Zein/PEG 纳米纤维用于生态友好型食品包装。

采用静电纺丝法制备了含有天然抗菌化合物的纳米纤维玉米蛋白/聚乙二醇基膜。对制备的纳米纤维的结构和热分析表明，不同的加工工艺对原始玉米蛋白聚合物的结构没有明显的影响。形态学表征表明，经丁香酚、百里酚、nisin或其组合改性的纤维具有较高的多分散性，平均纤维直径在300 ~ 390nm之间。含有丁香酚和百里香酚的纳米纤维样品可以抑制大肠杆菌和金黄色葡萄球菌的生长，而乳酸链球菌素或其与酚类物质的混合物对革兰氏阳性伊万诺氏李斯特菌具有较高的抗菌效果。具有生物活性分子的玉米蛋白/PEG膜可显著消除生物膜的形成，其中玉米蛋白/PEG/Eug/Thy组合效果最显著。生物活性膜的生物降解性测试表明，与对照样品相比，生物活性膜的降解过程没有明显减缓。富含酚/nisin复合物的玉米蛋白/聚乙二醇亲水性纳米纤维在可持续包装方面具有很高的发展潜力，可以提高食品的保质期和质量。

期刊介绍： New Biotechnology is the official journal of the European Federation of Biotechnology (EFB) and is published bimonthly. It covers both the science of biotechnology and its surrounding political, business and financial milieu. The journal publishes peer-reviewed basic research papers, authoritative reviews, feature articles and opinions in all areas of biotechnology. It reflects the full diversity of current biotechnology science, particularly those advances in research and practice that open opportunities for exploitation of knowledge, commercially or otherwise, together with news, discussion and comment on broader issues of general interest and concern. The outlook is fully international. The scope of the journal includes the research, industrial and commercial aspects of biotechnology, in areas such as: Healthcare and Pharmaceuticals; Food and Agriculture; Biofuels; Genetic Engineering and Molecular Biology; Genomics and Synthetic Biology; Nanotechnology; Environment and Biodiversity; Biocatalysis; Bioremediation; Process engineering.
