In this study, composite nanofiber films comprising polyvinyl alcohol, wheat gluten, and glucose (PWG) were fabricated using electrospinning, followed by crosslinking via Maillard crosslinking. Various mass concentrations of ferulic acid (FA) were incorporated into PWG films. The results indicated that the average diameter of the FA-PWG films decreased from 449 nm to 331 nm as the concentration of FA increased, until reaching a concentration of 12%; after which, a significant increase in diameter was observed. The subsequent Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and differential scanning calorimetry (DSC) results suggested that FA was distributed in the sample films in an amorphous form through hydrogen and ester bonds. Additionally, release experiments and antimicrobial tests on the FA-PWG sample films showed the good controlled release of FA and excellent anti- and activity of this film. These findings all indicate that the FA-PWG nanofiber film is a potential candidate for active food packaging.
在本研究中，采用静电纺丝法制备了包含聚乙烯醇、小麦面筋和葡萄糖（PWG）的复合纳米纤维膜，随后通过美拉德交联进行交联。将不同质量浓度的阿魏酸（FA）掺入PWG膜中。结果表明，随着FA浓度的增加，FA-PWG膜的平均直径从449 nm降至331 nm，直至达到12%的浓度；此后，观察到直径显著增加。随后的傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和差示扫描量热法（DSC）结果表明，FA通过氢键和酯键以无定形形式分布在样品膜中。此外，对FA-PWG样品膜的释放实验和抗菌测试表明，FA具有良好的控释性能，且该膜具有优异的抗菌活性。这些发现均表明，FA-PWG纳米纤维膜是活性食品包装的潜在候选材料。
