The butter batter was characterized by the highest jG*j value at
the initial temperature (25 C), as already commented on in the
frequency sweep. Different zones were observed in the curve
(Fig. 2A): a first zone, from 25 C to 38 C, where there was a sharp
decrease in jG*j associated with fat melting. An increase in tand is
observed over this temperature range (Fig. 2B), denoting a decrease
in the batter's viscoelasticity.
