Abstract: The inhibition activities of aqueous extract of Momordica charantia Linn to some food polluted microorganisms were studied. The results revealed that the inhibition effects of aqueous extract of Momordica charantia Linn on bacteria such as Staphy-lococcus aureus, Salmonella sp. , Escherichia coli and Bacillus sabtilis were good. On the other hand, the aqueous extract of Momordica charantia Linn was less efficient on inhibiting mould and yeast such as Aspergillus niger, Aaperiyillus oryzae, Penicillium citrinum, Saccharomyces cerevisiae, Rhodotoru laglutinnis and Candida sp.than inhibiting bacteria. The aqueous extract of Momordica charantia Linn had heating stability when temperature was not over 100 ℃. But with high temperature up to 121℃ with longtime effects of extract on antimicrobial activity decreased.

Key words: aqueous extract of Momordica charantia Linn, antimicrobial activity, heating stability
