Lactobacillus acidophilus and of direct acidification to minas frescal cheese production

Minas frescal cheese was produced in three different procedures: traditional manufacturing; with the addition of lactic acid; and with Lactobacillus acidophilus. Cheeses samples were analyzed for composition, and during the stock period of 30 days for acidity and L. acidophilus count. The sensory analysis was carried out through sensory affective methods. The composition of cheeses in different treatments presented results in accordance to the standards expected for the product, except for fat content, which was higher in cheese with the addition of lactic acid. During the stock period, an increase of titulable acidity in all treatments was observed. The L. acidophilus count was above 10(8)UFC/g, characterizing sufficient population to classify the cheese as a probiotic food. At the sensory analysis, it was attested that the cheese which had the addition of probiotic was preferred among the tasters. The Minas Frescal cheese was appropriate for incorporation of probiotic and the use of L. acidophilus in cheese improved the sensory quality and did not alter the physicochemical parameters.
