Dynamic shear moduli of isolated soy protein solutions upon heating were measured to monitor gelation. Onsets of gelation coincide with onset temperatures of denaturation in glycinin and β-conglycinin solutions, whereas in isolated soy proteins, onset of gelation was above denaturation temperature of β-conglycinin with storage modulus increasing in two steps. The first increase in storage modulus of isolated soy proteins occurred at about 78.5℃, while the second increase started at about 93℃. Gel properties of soy protein gels having different proportions of glycinin and β-conglycinin were measured by compression-decompression test.
