The total solids required for yogurt preparation were obtained by soy milk microfiltration and ultrafiltration.
Inulin was incorporated at the level of 20e70 g/L, and the soy milk containing inulin was fermented
using conventional microorganisms. The chemical, physical and sensory properties of the
products were evaluated. The membrane concentration of soy proteins leads to yogurts with an increase
of 59 g/L of proteins and 15 g/L of vegetable fats, reducing ash and anti-nutrients content. The clot had
high stability and protein concentration generated a buffer effect smoothing the acidity and the flavor
obtained is more agreeable. In addition, the proteins were concentrated without thermal treatment. As
the inulin content increased, creaminess and viscosity increased as well. The products prepared presented
nice smell, flavor and color, being the sample with higher global acceptability the yogurt with
50 g/L of inulin (P < 0.05).
