Can yoghurt syneresis be avoided?

The purpose of this research was to evaluate the physicochemical and sensory properties of a yogurt made with 3 levels of fat and using two types of stabilizer. A 2x3 bifactorial completely randomized design (CRD) was used. Factor A: Types of stabilizers, 2 g/L of CC-729 and 30 g/L of Inulin; Factor B: Milk at 1%, 2.5% and 4% fat, which originated six treatments, also a control was included (whole milk + unflavored gelatin), three repetitions were carried out resulting in 21 experimental units of 1000g. The physicochemical variables analyzed were: Syneresis, viscosity, pH, acidity and °Brix, whose results were evaluated through an analysis of variance in comparison to the witness through the significance test of Dunnett; resulting the factor A with incidence on all the variables, besides the inulin presented better results; while the factor B did not present significant differences on any variable.
