Evaluation of the effect of yacon in strawberry flavored kefir
This work aimed to evaluate the effect of yacon pulp on strawberry flavored kefir at 0, 2, 4 and 6% yacon concentrations and at 0, 14 and 28 days of manufacture. As for the most probable number of total and thermotolerant coliforms, the samples of the time 28 days were in accordance with the current...

As for the most probable number of total and thermotolerant coliforms, the samples of the time 28 days were in accordance with the current legislation, with counts < 3.0 MPN / g. The count of filamentous fungi and yeasts and lactic acid bacteria were in accordance with the legislation, and for yeast counts between treatments ranged from 104 to 106 CFU / g. The physicochemical analyzes were also in accordance with current legislation. For the acidity and pH, the treatments ranged from 0.42 to 1.05% of lactic acid and 4.09 to 4.65 respectively.
