Title: Impact of MG2+ and tara gum concentrations on flow and textural properties of WPI solutions and cold-set gels
Issue Date: 2010
Abstract: Cold-set gels of whey protein isolate (WPI) and of WPI plus tara gum (TG) were producedthrough the addition of magnesium chloride to heat-denatured (HD) WPI and WPI+TGsolutions. The flow behaviour of the WPI, TG, and WPI+TG samples was analyzed: WPIsolutions exhibit Newtonian behavior while the behavior of the TG and WPI+TG solutionscan be described through the Cross and Carreau models. The mechanical characterizationof the cold-set gels was done through puncture tests, and the Youngs modulus for each coldsetgel was obtained. Statistical analysis of the mechanical data was made according to theMarquadt-Levenberg algorithm.
