摘要： Porous adsorption, a less powerful adsorptive force than chemical bonds, is based on the physical adsorption of small molecules onto a solid surface that is capable of adsorbing gas or liquid molecules. Antimicrobial permutite composite (containing Ag+, Zn2+ and Ag+/Zn2+), starting from Linde Type A-permutite (LTA), was obtained in this research. The permutite samples were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), colorimeter and nitrogen adsorption technique. Cinnamon essential oil (CEO) was encapsulated into Ag+/Zn2+-permutite. The FT-IR and differential scanning calorimetry (DSC) confirmed that no chemical bond existed between CEO and Ag+/Zn2+-permutite. The loading capacity of Ag+/Zn2+-permutite/CEO was 313.07 mu L/g, and it had a sustained release effect. The Ag+/Zn2+-permutite/CEO showed stronger efficacy against Aspergillus niger and Penicillium sp. than Ag+/Zn2+-permutite. Ethyl cellulose pads modified by composite antimicrobial particles were applied in the preservation of Chinese bayberry. Compared to the control group, treatment with the Ag+/Zn2+-permutite/CEO antimicrobial pads resulted in a significantly lower decay incidence. In addition, the amount of migrated silver, zinc and aluminum from LTA was below the legal limit. These results confirmed that the ethyl cellulose pads modified by the Ag+/Zn2+-permutite/CEO provided an active packaging to control decay of fresh Chinese bayberry.
