Abstract

The anti-microbial activities of tea-polyphenol and the effects of the factors including concentration , pH value , temperature , NaCl concentration on the anti-microbial activities were studied by plate count and filtering paper method .The results showed that tea-polyphenol had strong inhibition on bacteria activities but no distinct inhibition on yeast and mold .The minimum anti-microbial concentration of tea-polyphenol was no more than 1.0 gL-1 and the optimum anti-microbial concentration was 4.0 gL-1 .Anti-microbial activities in natural pH value , neutral and low alkali environment were stronger than those in the high alkali environment .Anti-microbial activities of tea-polyphenol would not be affected in a certain temperature scope .NaCl could strengthen the anti-microbial activity of tea-polyphenol .[ Ch , 6 tab .18 ref .]
