本研究考察了姜黄提取物掺入对壳聚糖膜的抗菌性能和物理性能的影响。采用铸造法制备了姜黄壳聚糖基膜，并与硫酸钠交联。研究了薄膜的力学性能、光学性能、热学性能和透气性。在壳聚糖薄膜中加入姜黄后，膜的抗拉强度明显提高，膜的紫外-可见光阻隔性明显改善。红外光谱分析表明，壳聚糖的胺基与提取物中的酚类化合物存在相互作用。用平板计数琼脂法研究了壳聚糖膜对沙门氏菌和金黄色葡萄球菌的抑菌活性，发现加入姜黄后壳聚糖膜对沙门氏菌和金黄色葡萄球菌的抑菌活性较好。姜黄掺入壳聚糖薄膜具有较强的抗微生物活性和膜刚度，在食品包装方面具有广阔的应用前景。(C) 2017 Elsevier B.V.版权所有
In this study, the effects of turmeric extract incorporation on the antibacterialand physical properties of the chitosan films were evaluated. Turmeric containing chitosan-based film was produced with casting procedure and cross-linked with sodium sulfate. Mechanical, optical, thermal properties, and water vapor permeability of the films were studied. The addition of turmeric to chitosan film significantly increased the tensile strength of the film and improved the ultraviolet-visible light barrier of the film. Infrared spectroscopy analysis suggested an interaction between the phenolic compounds of the extract and amin group of chitosan. Antimicrobial activity of the chitosan films was studied against Salmonella and Staphylococcus aureus by plate count agar technique and a better antimicrobial activity was observed with turmeric incorporation. Turmeric incorporated chitosan films with enhanced antimicrobial activity and film stiffness can be suggested as a promising application for food packaging. (C) 2017 Elsevier B.V. All rights reserved.
