In this original research, biodegradable corn starch (CS) and wheat gluten (wg)-based silver nanofilms were synthesized and analyzed by using goji berry extract taurine (ta), garlic extract (GC), whey powder (wh), and montmorillonite clay nanoparticles. Antibacterial-corn-starch-based nano films were analyzed by using the methods of high-performance liquid chromatography (HPLC), Fourier Transform infrared spectroscopy (FTIR-ATR), X-ray diffraction (XRD), dynamic and mechanical (DMA) analysis, and scanning electron microscopy (SEM). In addition, the antibacterial resistances of the corn starch nano films against the bacteria and () and were examined and the migration assays were carried out. The migration analysis results of CS, CS, and CS nanocomposite films were found as 0.305, 0.297, and 0.297 mg/dm, respectively. The inhibition zone of CS, CS, and CS nanocomposite films were found as 1547, 386, and 1884 mm against bacteria. The results show that silver nanofilms are suitable as packaging films for the production of packaging in milk and dairy products, liquid foods, and acidic foods.
在这项原创研究中，使用枸杞提取物牛磺酸（ta）、大蒜提取物（GC）、乳清粉（wh）和蒙脱石粘土纳米颗粒合成并分析了基于可生物降解玉米淀粉（CS）和小麦面筋（wg）的银纳米薄膜。采用高效液相色谱法（HPLC）、傅里叶变换红外光谱法（FTIR-ATR）、X射线衍射法（XRD）、动态与力学（DMA）分析以及扫描电子显微镜（SEM）等方法对基于抗菌玉米淀粉的纳米薄膜进行了分析。此外，还检测了玉米淀粉纳米薄膜对细菌（此处括号内容缺失）的抗菌抗性，并进行了迁移试验。发现CS、CS和CS纳米复合薄膜的迁移分析结果分别为0.305、0.297和0.297毫克/平方分米。CS、CS和CS纳米复合薄膜对（此处细菌名称缺失）细菌的抑菌圈分别为1547、386和1884毫米。结果表明，银纳米薄膜适合作为牛奶和乳制品、液体食品以及酸性食品包装生产中的包装薄膜。
