結(jié)論

與對(duì)照薄膜相比，印刷薄膜表現(xiàn)出改善的水蒸氣阻隔性能。 Qo 印刷薄膜比混合薄膜更有效。 與對(duì)照薄膜相比，印刷的 Qo 薄膜的斷裂伸長(zhǎng)率降低，拉伸強(qiáng)度增加，而印刷的混合薄膜的伸長(zhǎng)率和拉伸強(qiáng)度均增加。

Th 納米封裝印刷的效率取決于印刷層數(shù)、接觸角、添加到分散體中的甘油量和薄膜類型。 兩種薄膜中 Th 的傳遞都在 8 天時(shí)完成，表明這些薄膜是傳遞活性化合物的良好平臺(tái)。 然而，NQoThs 在薄膜中的分布表現(xiàn)出不同的釋放曲線； Qo 薄膜在第一階段表現(xiàn)出突釋，而混合薄膜表現(xiàn)出較慢的釋放。

與使用 NQos 印刷的薄膜相比，使用 NQoThs 印刷的薄膜對(duì)革蘭氏陽(yáng)性菌（L. innocua 和 S. aureus）和革蘭氏陰性菌（S. typhimurium、E. aerogenes、P. aeruginosa 和 E. coli）表現(xiàn)出更高的 AM和對(duì)照膜。 革蘭氏陰性菌（鼠傷寒沙門氏菌、產(chǎn)氣大腸桿菌和大腸桿菌）獲得了最佳結(jié)果。

這些發(fā)現(xiàn)表明，可印刷納米技術(shù)的使用可以改善由可再生生物聚合物制備的薄膜的功能，因?yàn)檫@些薄膜可以提高水蒸氣阻隔性，作為傳遞活性化合物的良好平臺(tái)，并增加抗菌活性。 因此，這些薄膜可能有助于開(kāi)發(fā)新的食品包裝材料。
