Abstract

The production of antimicrobial sachet from silica-alginate-nanocellulose composite beads as carrier materials with the addition of nanocellulose (0, 1, 3, 5%) as nanofiller and cinnamon essential oil (CEO) as antimicrobial agent was investigated. The nanocellulose was isolated from oil palm empty fruit bunches by mechanical treatment using a combination of ultrafine grinding and ultrasonication. The produced composite beads were observed by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and x-ray diffraction (XRD) analysis. The produced composite beads with 5% nanocellulose (BDCN5) was more compact and spherical than others. Meanwhile, the produced antimicrobial sachets were performed with release characteristic and antimicrobial tests. The antimicrobial sachet with the addition of nanocellulose showed the cinnamon essential oil was significantly released from beads for 60 min and had a high inhibitory effect. Almost all microorganisms tested by BDCN5 showed a high inhibitory effect, 5.43% for inhibiting Escherichia coli, 5.19% for Salmonella sp, 3.36% for Aspergillus sp, and 8.72% for Staphylococcus aureus.

肉桂精油抗微生物微囊用硅-海藻酸盐-纳米纤维素复合微珠的生产

以二氧化硅-海藻酸盐-纳米纤维素复合微球为载体，添加纳米纤维素(0,1,3,5%)为纳米填料，肉桂精油(CEO)为抗菌剂，研究了其制备抗菌微囊的工艺。采用超细粉碎和超声波联合机械处理的方法，从油棕空果串中分离出纳米纤维素。采用扫描电子显微镜(SEM)、傅里叶变换红外光谱(FTIR)、热重分析(TGA)和x射线衍射(XRD)对制备的复合微珠进行了观察。所制得的含5%纳米纤维素(BDCN5)的复合微球比其他复合微球更致密、球状。同时对所制备的抗菌小袋进行了释放特性和抗菌性能试验。实验结果表明，添加纳米纤维素后，肉桂精油在60 min内明显释放，具有良好的抑菌效果。BDCN5对大肠杆菌、沙门氏菌、曲霉菌和金黄色葡萄球菌的抑制效果分别为5.43%、5.19%、3.36%和8.72%。
