其他摘要：Taking monascin as the research object, monascin was extracted from red kojic rice by ethanol extraction and extracted with 60%, 70% and 80% ethanol respectively. Finally, it was concluded that when the concentration of ethanol was 70%, the extraction rate of monascin was the highest, reached 75.68%. The bacteriostatic experiments of monascin extract and monascin fermentation showed that it had strong inhibitory effect on Staphylococcus aureus and Bacillus subtilis , weak inhibitory ability on Escherichia coli and Aspergillus niger , and no obvious inhibitory effect on the growth of Saccharomyces cerevisiae .
