The FAO/WHO defines probiotics as live microorganisms, which when consumed in adequate amounts, confer health benefits to the host (Moriya et al. 2006; Vasiljevic and Shah 2008). General agreement has not been reached concerning the minimum concentration of live probiotic bacteria at the time of consumption to confer health benefits (Donkor et al. 2006); however, the recommended concentrations in foods range from 6 to 8 log cfu/g (Ross et al. 2005; Vasiljevic and Shah 2008). The market for probiotic foods has grown rapidly, and yogurt is one of the most popular vehicles for consuming probiotics (Stanton et al. 2001).
The viability of probiotic bacteria in yogurt often decreases below the recommended concentration (6 log cfu/g) during storage because of low pH, high oxygen tension, increased redox potential (Eh) and increased hydrogen peroxide concentration (Dave and Shah 1997a, b; Lourens-Hattingh and Viljoen 2001; Donkor et al
