Role of caffeine and tannin in anti-toxigenic properties of coffee and tea.

AFB1, B2 , G1 and G2 produced by Aspergillus parasiticus var globosus in detannin-caffeinated coffee and black tea were five times more concentrated than in normal tea and coffee.  Exdtracts of normal coffee and tea powders significantly reduced aflatoxin production in liquid broth at 1 and 3% concentrations, with tea extract having a more pronounced effect than coffee extract.  Anti-aflatoxigenic properties appear to be due to tannin and caffeine which induced 95% inhibition of aflatoxin production at 0.3 and 0.6%, respecitively.
