摘要 将精油掺入活性包装材料,提高其有效利用率,选择香芹酚(carvacrol)作为精油模型,利用真空负载法将香芹酚封装在经4 mol/L盐酸刻蚀后的埃洛石纳米管中,制备了埃洛石纳米管-香芹酚复合物,进一步对埃洛石纳米管-香芹酚复合物进行聚电解质吸附包封,形成了控释体系。采用傅里叶变换红外光谱仪、透射电镜、氮气吸附、热重分析等手段表征了4 mol/L盐酸刻蚀后埃洛石纳米管的结构形貌和香芹酚负载量,并研究了香芹酚的释放速率。结果表明,经4 mol/L盐酸刻蚀后的埃洛石纳米管比表面积由29.506 m2/g增加到95.577 m2/g,香芹酚的负载量由6.7%增加到24.2%。吸附聚电解质层包封后,埃洛石纳米管-香芹酚复合物中香芹酚的初期快速释放得到显著改善,具有明显的控释效果,为精油在抗菌抗氧化食品包装材料中的应用提供了依据。

Abstract: To investigate the inclusion of essential oils in packaging materials, and improve its effective utilization rate, carvacrol were selected as the essential oil model, and halloysite nanotube-carvacrol composites were prepared by encapsulating carvacrol in halite nanotubes etched with 4 mol/L HCl, using a vacuum process. The controlled release system was prepared by polyelectrolyte encapsulation. The structure and morphology of halloysite nanotube etched with 4 mol/L hydrochloric acids, the carvacrol load and the release rate of carvacrol were characterized by using fully automatic surface and porosity analyzer, transmission electron microscope, Fourier infrared spectrometer and thermogravimetric analyzer stability. The results showed that the specific surface area of halloysite nanotube increased from 29.506 m2/g to 95.577 m2/g, and a load of carvacrol increased from 6.7% to 24.2%. Using polyelectrolyte encapsulation, the releasing of carvacrol in the composites was decreased significantly, and it had an obvious controlled-release effect. These results provided the basis for the application of essential oil as antibacterial and antioxidant food packaging materials.
