Micellar-type aggregates of HP-β-CD/GML inclusion complex: Increased water-solubility and effective antibacterial capabilities.

The inclusion complex (IC) was successfully obtained by encapsulating glycerol monolaurate (GML) into the cavity of hydroxypropyl-β-cyclodextrin (HP-β-CD). Compared with solubility of pure GML <80 μg/mL in water, and the water-solubility of encapsulated GML was significantly improved and reached to 270,000 μg/mL. IC can form nanoparticles by self-assembly, probably assigned to its strong capability to form micellar-type aggregates.

Cellulose laurate films containing curcumin as photoinduced antibacterial agent for meat preservation.

Hydrophobic cellulose laurate (CL) with high degree of substitution has been successfully synthesized. The mechanical property, water-resistance, antimicrobial activity, barrier properties and food decontamination of cellulose-laurate-curcumin films (CL-Cu, x = 0.1, 0.

Cellulosic films reinforced by chitosan-citric complex for meat preservation: Influence of nonenzymatic browning.

The methods to obtain cellulose-chitosan composite films exhibiting excellent water-resisting and antibacterial abilities have been widely explored. Cellulose-chitosan-citric films (C-Ch-F) were successfully obtained by a facile coating of chitosan-citric complex on the surface of cellulose. The occurrence of nonenzymatic browning at 80 °C improved the thermal stability, water-resistance, mechanical property and oxygen-barrier ability of C-Ch-F membranes.

Photoinduced Antimicrobial Activity of Curcumin-Containing Coatings: Molecular Interaction, Stability and Potential Application in Food Decontamination.

Polyvinyl acetate () and curcumin () were utilized for preparing new protecting ( = 1, 5 and 10) coatings exerting antimicrobial photodynamic activity upon white light irradiation. Toward or , the killing efficiency represented the dependence on the concentration and irradiation intensity. Toward , the killing efficiency of coating reached 93% at an energy density of 72 J/cm.

Preparation of Elastic and Antibacterial Chitosan-Citric Membranes with High Oxygen Barrier Ability by in Situ Cross-Linking.

Chitosan-citric biomembranes ( = 0-3) were prepared by a simple cross-linking. The dependence of mechanical property, water-resisting capacity, microstructural characteristic, oxygen barrier ability, and thermal properties of membranes on the content of glycerin was investigated. The results revealed that vacuum drying at 80 °C can lead to low-yield amidation and the Maillard reaction, thus affecting the thermal stability and water resistance of biomembranes.
