THE SUPPLEMENTARY EFFECT OF BLACK AND GREEN TEA INFUSION ON ANTIMICROBIAL ACTIVITIES OF KEFIR

The influence of supplementation with green and black tea on microbiological properties and antimicrobial activities of kefir was investigated during 21 days of storage. The samples supplemented with 2% either green or black tea had higher viable counts of both kefir cultures than those of supplemented with the ratio of 4%. Both green and black tea extracts showed antimicrobial activity on Escherichia coli, Bacillus cereus, Staphylococcus aureus, Candida albicans however this effect was detected higher in samples containing green tea.
