In the current study, film based on semi-refined ι-carrageenan/cassava starch (SRiC/CS) incorporated with SiO-ZnO nanoparticles was fabricated and characterized to deal with serious environmental problems resulting from plastic packaging materials. This study aimed to evaluate film properties with the variation of SRiC/CS proportions of bionanocomposite films for application to minced chicken meat packaging. Increasing CS portion contributed to increased transparency, reduced surface roughness, and decreased mechanical properties of films. The variable significantly ( < 0.05) increased the water vapor permeability (WVP) and reduced the water solubility of films. The incorporation of the nanoparticles significantly ( < 0.05) increased UV screening, decreased WVP, and enhanced the antimicrobial activity of films. Furthermore, the substitution of 0.5 wt% (weight percentage) CS provided the best film characteristics. Based on the color and the total volatile base nitrogen (TVBN) results, SRiC film incorporated with the nanoparticles preserved minced chicken quality up to six days. Thus, the developed films are desirable for biodegradable food packaging.
在当前研究中，制备并表征了基于半精制ι-卡拉胶/木薯淀粉（SRiC/CS）并掺入SiO-ZnO纳米颗粒的薄膜，以解决塑料包装材料导致的严重环境问题。本研究旨在评估生物纳米复合薄膜中SRiC/CS比例变化时薄膜的性能，以应用于碎鸡肉包装。增加CS比例会导致薄膜的透明度提高、表面粗糙度降低以及机械性能下降。该变量显著（<0.05）增加了薄膜的水蒸气透过率（WVP）并降低了其水溶性。纳米颗粒的掺入显著（<0.05）提高了紫外线屏蔽能力，降低了WVP，并增强了薄膜的抗菌活性。此外，用0.5 wt%（重量百分比）的CS替代可提供最佳的薄膜特性。基于颜色和总挥发性盐基氮（TVBN）结果，掺入纳米颗粒的SRiC薄膜可将碎鸡肉的品质保持长达六天。因此，所开发的薄膜适用于可生物降解的食品包装。
