AI Article Synopsis
- A new antibacterial nano-hydrogel (GEONH) was created using a combination of microfibrillated cellulose and carboxymethyl chitosan, enhanced with ginger essential oil nanoemulsion for effective preservation.
- The optimal mass ratio of the components was found to be 1/9/270, yielding favorable properties like prolonged gel time and water absorbency, supported by X-ray diffraction and FT-IR analysis.
- GEONH demonstrated strong antibacterial effects on various bacteria and improved the quality of stored boiled salted duck, marking it as a potential fresh-keeping packaging solution for meat products.
Article Abstract
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.

Liver fibrosis is a significant contributor to global morbidity and mortality, making the identification of non-toxic natural therapies to slow its progression essential. This study evaluated the anti-fibrotic potential of a nutraceutical blend comprising extra virgin olive oil, linseed oil, and ginger extract, formulated in both emulsion and nanoemulsion forms, using a rat model of liver fibrosis. Nanoemulsions were prepared using the ultrasonication technique, and their particle size and stability were analyzed via the DLS method.

To improve the packaging properties of pea protein isolate (PPI) films, 2 wt% of essential oil (EO) from garlic, ginger, or cinnamon was individually incorporated into the films. The film properties were evaluated after the addition of EOs. The resulting PPI active films were applied to salmon to explore their efficacy in a real food system.
