We used transient and oscillatory tests to determine various
parameters [viz. S, An and the difference (G0
0 G00
0)] that
can be used as measures of gel strength as confirmed by the
two types of tests. A starch increased content provides firmer,
stiffer viscoelastic networks with high viscoelastic
moduli. The improvement was more uniform is the PW
samples than in the AP samples. The latter exhibit a discontinuity
at a starch concentration near 11% which can
be taken as the optimum starch content. Hence the need
to accurately control the amount of starch that is added
to such samples.
