Description The handling of rice flour doughs in terms of sheeting,
flattening and rolling is difficult due to the absence of
gluten forming proteins; scope exists to improve these characteristics
by incorporating appropriate additives during the
preparation of rice doughs. Different levels of additives such
as whey protein concentrate (WPC) (0–10 %), xanthan gum
(0–5 %), sucrose (0–20 %) and salt (0–2 %) have been
incorporated, and the rheological (small-deformation
oscillation) as well as sensory characteristics have been determined,
in addition to microstructural observations and finding
inter-relationships. The second order polynomial can adequately
explain the rheological parameters like storage modulus,
loss modulus and complex viscosity (R=0.863–0.889,
p≤0.01) while it is poor for phase angle (R=0.659, p≤0.01).
Among these additives, xanthan gum imparts the strongest
effect (significant at p≤0.01) followed by whey protein concentrate.
The effects of these additives are predominantly
linear though quadratic effects are also significant in several
cases. A cohesive microstructure with improved binding occurs
with a high level (7.5 %) of WPC. It is concluded that a
judicious selection of additives in appropriate levels can develop
rice doughs that possess the desirable handling properties
leading to preparation of products.
