Not only wheat flour but also other flour
types have been investigated for developing cakes
of lower cost and better quality in terms of
consumer acceptance (Turabi et al., 2008). The
cakes studied were prepared from various types
of flour such as wheat-chickpea flour blends
(Gomez et al., 2008), rice flour (Turabi et al., 2008)
and flour obtained from wheat, rye, and barley
(Gomez et al., 2010). Tapioca starch (TS),
produced from cassava roots, is a thickener used
in the food industry due to its high viscosity, clear
appearance and low production cost compared to
other starches, especially in Thailand. However,
the effect of partial substitution of wheat flour
(WF) with TS on the quality of the batter and the
sponge cake has rarely been investigated.
