Rheologically determined melting and setting points
were close to those obtained calorimetrically (Table 1).
Although the incorporation of konjac glucomannan
decreased rather than increased the enthalpy change due
to the kappa carrageenan setting and melting transition, it
made a major contribution to the rheology of the gel. The
addition of 0.3% konjac glucomannan to 0.3% kappa
carrageenan more than doubled the G0 value obtained on
cooling to 25 8C and showed a large relative increase in the
Young’s modulus (E) obtained from the compression
experiments.
