Preparation,Characterization and Application of Compound CuO/CaMoO4 Antibacterial Agent in Cucumber Storage
ZHANG Huimin
Abstract：In this paper,ammonium molybdate,eggshell and cetyltrimethyl ammonium bromide were used as raw materials to prepare CaMoO4 with improved performance by adjusting the calcination temperature.Additionally,a CuO/CaMoO4 composite antibacterial agent was synthesized using calcium molybdate,copper sulfate,and sodium borohydride as raw materials.The effects of CuO/CaMoO4 antibacterial dosage,culture time,and copper content on antibacterial activity and the antibacterial effect of CuO/CaMoO4 on Escherichia coli(E.coli)were studied under light and dark reaction conditions.The CuO/CaMoO4 composite antibacterial agent synthesized at 650℃exhibited the best antibacterial efficacy.Moreover,when the copper content was 1.20%,the antibacterial rate could reach 100%under light and dark conditions.Bacteriostatic testing of plastic wrapping material containing CuO/CaMoO4 compound antibacterial agent showed that the agent could effectively inhibit E.coli on food surfaces,and the antibacterial rate remained at 100%even after four days of storage.Furthermore,the CuO/CaMoO4 antibacterial compound displayed excellent biocompatibility.Overall,the compound CuO/CaMoO4 antibacterial agent demonstrated rapid and efficient inhibition of E.coli,thereby ensuring food safety and offering novel insights for food storage practices.
