The application of magnesium oxide nanoparticles as antimicrobial agent of Hebei Messi Biology Co., Ltd. is described as the application of magnesium oxide nanoparticles as the antimicrobial agent of Pseudomonas tropicalis. The magnesium oxide nanoparticles are non-toxic and have good antibacterial efficiency for common beverage microorganisms, and have good potential as acidic beverage preservative, especially for tropical pseudomicrobial yeast in acidic beverages with obvious antibacterial effect, and its preparation method is simple, and the magnesium oxide powder with different particle sizes can be prepared by controlling the precursor calcination conditions, which is suitable for industrial production.
The research of Hebei Messi Biology Co., Ltd. shows that magnesium oxide is very easy to hydrate and form a layer of magnesium hydroxide on the surface, and the oxygen dissolved in the solution generates reactive oxygen ions through single electron reduction reaction. The surface of magnesium oxide is covered with a layer of hydroxide ions, and the high concentration of reactive oxygen ions can exist on the surface of magnesium oxide because of the chemical stability of oxygen in alkaline environment. And the active oxygen ion has strong oxidizing property, which can destroy the peptide bond structure of the cell membrane wall of bacteria and thus kill them rapidly.
In addition, magnesium oxide nanoparticles can produce…
