The water sorption isotherms of binary mixtures, prepared by corn starch and isolated soybean protein (ISP) or casein, were measured and analyzed. Simple equations to predict moisture content from knowledge of composition and water activity of the mixture were derived by applying Response Surface Analysis. Comparison between predicted and experimental moisture content for 13 combinations of corn starch-ISP mixture at the range of 0.25-0.87 resulted in a maximum error of only 6.06% and an absolute mean error of 2.60% and for the mixture of corn starch-casein the error was -4.39% and 2.12%, respectively
