本研究旨在报道纳米胶囊丁香精油 (CEO) 作为天然食品防腐剂及其通过 3D 纳米网络多孔淀粉基材料 (3D-NPS) 增强抗菌活性。首次使用马铃薯淀粉通过牺牲模板方法制造了加载 3D-NPS 的 CEO。研究了 CaCO3NPs 浓度、封装效率、温度和抗菌活性对负载 CEO 的 3D-NPS 特性的影响。所制备的 CaCO3NPs/淀粉含量为 3:2 的 3D-NPS 显示出良好的均匀性，几乎呈蜂窝状，通道直径约为 200−300 nm。包封CEO后，负载CEO的3D-NPS的最大包封率达到86.7%，并且具有增强的热处理稳定性。 3D-NPS 中 CEO 的缓释特性可以通过伪一级动力学模型准确描述。此外，加载 3D-NPS 的 CEO 不仅显示出对 B.枯草芽孢杆菌、金黄色葡萄球菌和大肠杆菌，还能显着延长CEO的抗菌活性持续时间。这种制备3D-NPS的新方法简单、无毒、产率高，为不稳定精油或其他物质的封装和持续释放提供了一个有前景的平台。
This study aimed at reporting on the nanoencapsulate clove essential oil (CEO) as natural food preservative and its enhancement in antimicrobial activities by 3D nanonetwork porous starch-based material (3D-NPS). 3D-NPS loaded CEO were fabricated via a sacrifice template approach using potato starch for the first time. The effects of the CaCO3NPs concentration, encapsulation efficiency, temperature, and antimicrobial activity on the CEO-loaded 3D-NPS characteristics were investigated. The as-prepared 3D-NPS formed as the content of CaCO3NPs/starch at 3:2 showed good uniformity and almost honeycomb shape, with channel diameters of about 200−300 nm. After encapsulation of CEO, the maximum encapsulation efficiency of CEO-loaded 3D-NPS reached 86.7 %, and it possessed enhanced stability against thermal treatment. The slow-release properties of CEO from 3D-NPS was describe exactly by the pseudo-first-order kinetics model. Moreover, the CEO loaded 3D-NPS not only revealed greatly enhanced antimicrobial activity againstB. subtilis, S. aureus, and E. coli, but also significantly extended the duration of the antimicrobial activity of CEO. This novel method for the preparation of 3D-NPS is simple, non-toxic, and high-yield, exhibiting a promising platform for encapsulation and sustained release of unstable essential oils or other substances.
