This study is the first to report the successful application of the
newly identified potential probiotic P. jensenii 702, in goat’s milk
yogurt. Inoculation of approximately 108 cfu/g appeared to be sufficient
to sustain the viability of P. jensenii 702 and B. animalis
subsp. lactis BB-12 at levels above the minimum therapeutic
threshold (106 cfu/g) in both plain and stirred fruit yogurts.
Although viable numbers of L. acidophilus LA-5 were not maintained
above this threshold over the shelf life in any of the preparationspreparations,
the results indicated that the viability of this probiotic
strain can be improved in goat’s milk yogurt by addition of fruit
juice to the product. Addition of fruit juice resulted in a significant
increase in pH and syneresis and a significant decrease in viscosity
and water holding capacity of yogurt base. Addition of fruit juice
also appeared to improve the sensory characteristics of probiotic
goat’s milk yogurts.
