Study on antimicrobial and preservation effect of the ethanol extract from honey pomelo peel
摘要
Abstract
The ethanol extract was prepared from honey pomelo peel,and its antimicrobial effect on Escherichia coli,Staphylococcus aureus,Bacillus subtilis,Saccharomyces cerevisiae and Aspergillus niger were studied. The filter paper diffusion method and solid dilution method were used to determine the antimicrobial activity and the minimal inhibitory concentration（MIC）,respectively. The influence of the temperature and pH on the antimicrobial effect was studied also. Meanwhile,the preliminary preservation test of fruit and vegetable was conducted. The results showed that ethanol extract of pomelo peel had a strong antimicrobial activity to Staphylococcus aureus,Bacillus subtilis,Saccharomyces cerevisiae and the minimum inhibitory concentration was as follow：6. 25%,12. 5%,12. 5%,respectively,but no significant effect to the Escherichia coli and Aspergillus niger. The antimicrobial effect was little affected by temperature,while influenced largely by pH and strong effect in acid condition. The ethanol extract from honey pomelo peel had better antimicrobial and preservation effect,and could be developed as a natural food preservative agent.关键词
