Abstract

Objective(s): Bioactive compounds like curcumin can be incorporated into food packaging formulation either to enhance physico-mechanical properties or to improve the biological activity of the packaging systems. Furthermore, it enables the packaging to monitor the changes in food quality. Materials and Methods: In the present study, the effect of curcumin concentration (0.2, 0.4 and 0.6%) on physico-mechanical and biological activity of soluble soy bean polysaccharide (SSPS)/TiO2 nanoparticles nanocomposites were investigated. Additionally, the release behavior of this bioactive compound from the developed film was tested. Finally, the color changing of SSPS/TiO2 nanoparticles/curcumin nanocomposites in contact with different mediums were examined. Results: When the curcumin concentration increased up to a certain point (0.4 %), the physical and mechanical properties of the film improved, but beyond this point, an opposite effect was observed. SSPS/TiO2 nanocomposite showed strong antibacterial activity against both gram positive and negative bacteria. Small amount of curcumin released in ethanol as a food simulant. Conclusion: The films incorporated by curcumin can be used as promising packaging systems for non-destructively detecting quality and freshness of foods.
姜黄素负载可溶性大豆多糖/TiO2生物纳米复合材料的制备及其抗菌性能的研究
目的:姜黄素等生物活性化合物可以掺入食品包装配方中,以提高包装系统的物理力学性能或提高其生物活性。此外,它使包装能够监测食品质量的变化。材料与方法:研究了姜黄素浓度(0.2%、0.4%和0.6%)对可溶性大豆多糖/TiO2纳米复合材料物理力学和生物活性的影响。此外,测试了这种生物活性化合物从所开发的膜中的释放行为。最后,研究了SSPS/TiO2纳米颗粒/姜黄素纳米复合材料在不同介质中的颜色变化。结果:当姜黄素浓度增加到一定程度(0.4%)时,薄膜的物理和机械性能有所改善,但超过这一点,观察到相反的效果。SSPS/TiO2纳米复合材料对革兰氏阳性菌和阴性菌均表现出较强的抗菌活性。少量姜黄素在乙醇中作为食物模拟物释放。结论:姜黄素薄膜可作为无损检测食品质量和新鲜度的包装体系。
