heating. The electrical conductivity responses to different voltage levels show clear cuts around 60˚C, at this
temperature the oil body of the soya milk is released. At temperatures around 75˚C and 80˚C, the electrical con-
ductivity response reaches a minimum saddle and starts to increase. These two temperatures correspond to the
release of the 7S and 11S proteins, major proteins in tofu produce. Hence the electrical conductivity measur e-
ment could be a fast, convenient, and non-destructive tes ting method for on-line indicatio n of tofu quality.
