The rheological and cooking properties of gluten-free noodles prepared with dry- and wet-milled rice
flours were characterized. Dry-milled rice flour with a higher degree of starch damage exhibited greater
water hydration properties than wet-milled rice flour at room temperature. However, the pasting results
of rice flour suspensions demonstrated that wet-milled rice flour showed a higher value of peak viscosity
due to its great swelling power upon starch gelatinization. The similar thermo-mechanical tendency was
observed in a rice dough system by Mixolab. In the planar extensional test, the noodle dough sample prepared
with dry-milled rice flour exhibited higher elongational viscosity which could be favorably correlated
to more resistance of dry-milled rice noodle strands to extension. When rice noodles were cooked,
increased cooking loss was observed in dry-milled rice noodles which was attributed to great water solubility
derived from a higher degree of starch damage.
