Abstract
The present invention discloses a novel nano-composite antibacterial material and a preparation method and an application thereof, and belongs to the technical field of preservative materials. The novel nano-composite antibacterial material disclosed by the present invention is prepared by mixing a dimethylimidazole solution, deionized water and a zinc nitrate solution to prepare a metal-organic framework carrier, compositing with nisin to form a nano antibacterial composite material, separating out from a solution in a precipitate form, centrifuging, removing a supernatant, cleaning and re-suspending with the deionized water. The novel nano-composite antibacterial material prepared by the present invention has an antibacterial effect superior to nisin having a same concentration. The present invention prominently improves an antibacterial activity and thermostability of the nisin under neutral and slightly alkaline conditions, effectively promotes antibacterial property and a usable range of the nisin, and further expands an application field of the metal-organic framework carrier.
