Viscosity of the batter is another factor that can affect the quality
of the product. The increase in viscosity diminishes foam
expansion and thus, the greater volume of batter is required to
ensure the mold filling and a resulting well-shaped product [31].
Generally, batters with higher starch contents have higher viscosity.
Addition of fibers and fillers also increases the batter viscosity.
In case of malt bagasse addition, Mello and Mali [55] reported that
water content used in each formulation was related to the minimal
content to produce a homogeneous dispersion. This work suggested
that the higher water content was required to maintain
the fluidity of the starch paste with increasing the bagasse content.
Even though, the formulation with 5 and 10 wt% of malt bagasse
enhanced foaming ability of starch. At higher concentration of
bagasse, a longer baking time has to be applied and, as a consequence,
the production yields decreased in comparison to the formulation
with lower concentration of bagasse.
