Unlike potato starch, the strain at yield in wheat starch-based foam decreased with increased latex amounts until 18 wt% of water (samples W-1 to W-8 of Table 1). At 27 wt% of latex to water, the strain at yield increased compared with 18 wt% of latex to water. These observations remained consistent with or without CaCO3 present in the batter. The stress at yield and modulus generally decreased with increased amounts of latex, as seen in foams prepared with potato starch. However, these decreases for wheat starch were not as dramatic as found with potato starch (Table 1). Also, the increase in the density resulting from increased latex content in the batter was comparatively much lower than foams with potato starch. The addition of CaCO3 to the formulation appears to decrease strain at yield while slightly raising the modulus and density. As with potato starch, MC decreased with increased latex, and there was a small difference in MC between foams with or without CaCO3.
