UNLABELLED
An antibacterial nano-hydrogel (ginger essential oil nanoemulsion hydrogel, GEONH) based on Schiff base reaction was prepared using double-formaldehyde micro fibrillated cellulose (DAMFC) and carboxymethyl chitosan (CMCS) loaded with ginger essential oil nanoemulsion (GEON). It was found that when the mass ratio of DAMFC/CMCS/GEON was 1/9/270, the gel time, the water absorbency, gel strength, and morphology were the best. The results of X-ray diffraction and FT-IR confirmed that the aldehyde group on the DAMFC molecular chain formed a stable chemical crosslinking with the amino group on the CMCS molecular chain, resulting in a change in the crystal structure. GEONH showed excellent bactericidal activity against , , and . Simultaneously, the prepared GEONH decreased the total viable count, Malondialdehyde, and total sulfhydryl content and improved the taste in the storage of boiled salted duck. Therefore, GEONH film is a promising fresh-keeping packaging for storing meat products.

采用负载姜精油纳米乳液（GEON）的双醛微纤化纤维素（DAMFC）和羧甲基壳聚糖（CMCS），通过席夫碱反应制备了一种抗菌纳米水凝胶（姜精油纳米乳液水凝胶，GEONH）。研究发现，当DAMFC/CMCS/GEON的质量比为1/9/270时，凝胶时间、吸水率、凝胶强度和形态最佳。X射线衍射和傅里叶变换红外光谱结果证实，DAMFC分子链上的醛基与CMCS分子链上的氨基形成了稳定的化学交联，导致晶体结构发生变化。GEONH对[具体细菌名称1]、[具体细菌名称2]和[具体细菌名称3]表现出优异的杀菌活性。同时，制备的GEONH降低了盐水鸭贮藏过程中的总活菌数、丙二醛和总巯基含量，并改善了风味。因此，GEONH薄膜是一种很有前景的肉类保鲜包装材料。
