In the current study, cornstarch-based antimicrobial and edible films were designed using solution-casting methods. The medicinal plants (, and ) reinforced the gelatinized solution in different concentrations as fillers. The effect of plant extracts on antimicrobial and antioxidant potential, microstructure, barrier, thermal and mechanical properties of cornstarch-based films (SBFs) was investigated using antimicrobial activity, DPPH free radical scavenging values, scanning electron microscopy, X-ray diffraction, water vapor transmission rate, differential scanning calorimetry, and tensile strength. Likewise, it was depicted that the geometric and crystalline structures of medicinal plants' reinforced films remained the same even after processing. The mechanical tests indicated that the plant extracts effects are associated with reduced elongation, increasing tensile strength, and Young's modulus. Morphological analysis revealed the generation of uniform and the compact surfaces. However, films with 10% concentration of plant extracts have the lowest water vapor permeability values, and emerged better barrier properties. Moreover, these films showed the significant antioxidant potential and antimicrobial activity.
在当前研究中，采用溶液浇铸法设计了基于玉米淀粉的抗菌可食用薄膜。药用植物（、和）以不同浓度作为填料增强糊化溶液。使用抗菌活性、DPPH自由基清除值、扫描电子显微镜、X射线衍射、水蒸气透过率、差示扫描量热法和拉伸强度，研究了植物提取物对基于玉米淀粉的薄膜（SBFs）的抗菌和抗氧化潜力、微观结构、阻隔性、热性能和机械性能的影响。同样，结果表明，即使经过加工，药用植物增强薄膜的几何结构和晶体结构仍保持不变。力学测试表明，植物提取物的作用与伸长率降低、拉伸强度和杨氏模量增加有关。形态分析显示生成了均匀且致密的表面。然而，植物提取物浓度为10%的薄膜具有最低的水蒸气渗透率值，并表现出更好的阻隔性能。此外，这些薄膜显示出显著的抗氧化潜力和抗菌活性。
