RESULTS AND DISCUSSION
Quality of cake batter with and without tapioca
starch
The flow curves of the cake batters
containing different mixing ratios of WF and TS
(100:0, 75:25, 50:50) were determined from steady
shear measurements at 25 °C. All batters with and
without TS exhibited a pseudoplastic behavior. The
apparent viscosity of the batters decreased with
increasing shear rate and TS substitution for WF
(Figure 1a). The results obtained were in good
agreement with the results obtained from batters
containing WF and TS mixtures for fried products
(Ketjarut et al., 2010). Therefore, the WF content
in the cake batter played a predominant role in
increasing the batter viscosity due to the wheat
protein being the main cause of batter viscosity
development during mixing (Loewe, 1993).
