The grinding treatments can induce physical conversion of the
starch granules, including the reduced crystalline region in starch
and increasing starch damage, and thus caused a change in starch
properties. The change is strongly associated with starch swelling
and gelling behaviors, which can greatly influence the RVA curves
(Ryu et al., 1993). Peak viscosity was reported as one of the main
quality parameters of cooked dry Chinese noodles, which significantly
correlated positively with the values of stickiness and
smoothness, and final viscosity was indicative of the retrogradation
tendency of amylose in starch (Liu et al., 2003). The results indicated
that the reduced degree of crystallinity after grinding might
have deteriorative effect on the sensory quality but decrease the
retrogradation degree of starch in noodle. The small extent of
decline in the three viscosity values of RVA profiles might be
attributed to the fact that the superfine grinding process applied in
the study was not sufficient to produce WWF with severely
destroyed crystalline structure in the starch.
