Abstract :
Among the fermented products, cheese has a good potential to deliver probiotic microorganisms into the gastrointestinal system due to its high protein and fat contents. The contamination of milk with aflatoxin M deserves attention concerning cheese consumption due to the harmful effects on human health. In the present research, the reduction of aflatoxin M1 (AFM1) by two well-known probiotic strains was studied in artificially aflatoxin-contaminated Feta cheese. Changes in pH, the viability of the probiotic strains and the level of aflatoxin in the samples were analyzed during 60-day storage. The results showed that all samples containing probiotics dramatically reduced the AFM1 levels. From both the health and economic aspects, the B. bifidum species at an inoculation level of 107 CFU/mL has proven to be the best treatment, due to the lowest cost of probiotics, highest survival rate, and 30.12% reduction of AFM1.
