Desarrollo de una leche fermentada de cabra con cultivos probióticos.

The goat milk for their multiple properties nutraceutical and for the high yield of their derived products, it represents an interesting commercial alternative for the elaboration of special fermented milk. At the present time the probiotics starter culture for their proven properties are used thoroughly in the elaboration of fermented milk. Keeping in mind these antecedents this work had as objective to develop a fermented milk of goat with characteristic probiotics, good acceptability and appropriate shelf life using the starter culture Lactobacillus casei, Lactobacillus acidophilus jointly with the starter culture of the yogurt. It was carried out a design of experiment of response surface (2²) with the independent variables, starter culture dose (1.5 to 2.5%) and the relationship of starter culture of yogurt: probiotics starter culture 1:3 at 1:5. As variable answers they took: the viability, the acidity and the sensorial indicators. The formulation selected with the best characteristics was conserved to temperature of 4 oC for the evaluation of the storage life. The best formulation was the 2% starter culture with a relationship of 1:4. The fermented milk was evaluated of "I like" and its viability was above the therapeutic minimum until the 21 days (log (UFC/ml) of 8.8 at 7.0). [ABSTRACT FROM AUTHOR]
