✦ Synopsis
The effect of heating temperature and duration (f = 80-120 "C and 7 = 10-50 min) on gelation of the soy bean globulins solutions has been studied using the method of mathematical planning of experiment and taking the shear modulus (G) of the gel as an equivalent of the degree of conversion. The G ( t , z) depence hdS been found to have an only maximum at f = 88 f 2 "C and t = 42 f 2 min, irrespective of gel concentration values C = 10-18.5 wt. %. Under these conditions. the concentration dependence of shear modulus is described by empirical relation G = a . C'.67. These results indicate that there exists a certain physical similarity of gelation mechanism at different values of c'.
