Abstract

This study evaluated antioxidant and antimicrobial properties of chitosan gel (Cs-gel) functionalized with cinnamaldehyde oil (CN) and orange peel-derived flavonoid extract (Fs) using the ionic-gelation method. Results showed that the encapsulation efficiencies of CCF-9 and CCN were 83.14 ± 3.34 and 80.56 ± 1.17%, respectively. The interaction of CN or Fs on Cs-gel indicates the presence of H-bonding formation, as observed by UV–vis spectroscopy, Fourier transform infrared spectrophotometry (FTIR), and Raman-spectroscopy showed a good corroboration with Surflex-dock findings. Scanning electron microscopy also showed the integration that occurred between Cs and both ligands, which was further supported with X-ray diffraction and X-Ray photoelectron spectroscopy spectra. The textural properties of CCF-5 gel showed high hardness, chewiness, and gumminess values, indicating that the integration of Fs and CN altered the microstructure of Cs-gel. Chotison-functionalized based gels exhibited higher antioxidant abilities against DPPH and ABTS free radicals than Cs-gel. The CCF-9 gel showed a good inhibition value of 29.91 ± 1.22 and 93.61 ± 2.12% against Penicillium expansum and Alternaria westerdijkiae, respectively. Additionally, CCF-9 inhibition zones against Staphylococcus aureus, Escherichia coli, and Bacillus cerues were 28.65 ± 0.05, 27.69 ± 0.04, and 26.16 ± 0.02 mm, respectively. These findings demonstrated the potential antioxidant and antimicrobial effects of functionalized chitosan gel indicating its potential as a bioactive additive for food preservation.

使用双重交联剂使壳聚糖与黄酮提取物和肉桂醛油双重凝胶功能化:特性、抗氧化和抗菌效果
本研究采用离子凝胶法评估了肉桂醛油(CN)和橙皮黄酮提取物(Fs)功能化壳聚糖凝胶(Cs-凝胶)的抗氧化和抗菌特性。结果表明,CCF-9 和 CCN 的封装效率分别为 83.14 ± 3.34% 和 80.56 ± 1.17%。通过紫外-可见光谱、傅立叶变换红外分光光度法和拉曼光谱的观察,CN 或 Fs 在 Cs-gel 上的相互作用表明存在 H 键的形成,这与 Surflex-dock 的研究结果很好地印证了这一点。扫描电子显微镜也显示了铯与两种配体之间的整合,X 射线衍射和 X 射线光电子能谱也进一步证实了这一点。CCF-5 凝胶的质构特性显示出较高的硬度、咀嚼度和胶粘性,表明 Fs 和 CN 的融合改变了 Cs 凝胶的微观结构。基于 Chotison 功能化的凝胶对 DPPH 和 ABTS 自由基的抗氧化能力高于 Cs-凝胶。CCF-9 凝胶对扩张青霉和西双版纳Alternaria的抑制率分别为 29.91 ± 1.22% 和 93.61 ± 2.12%。此外,CCF-9 对金黄色葡萄球菌、大肠杆菌和陶瓷芽孢杆菌的抑制区分别为 28.65 ± 0.05、27.69 ± 0.04 和 26.16 ± 0.02 毫米。这些研究结果表明,功能化壳聚糖凝胶具有潜在的抗氧化和抗菌作用,表明其具有作为食品保鲜生物活性添加剂的潜力。
