Abstract

An empirical equation is available for predicting apparent water diffusivity in rice starch/water system in arbitrary moisture content and at arbitrary temperature. In the present paper, water diffusivity in wheat starch (wheat flour) /water system was measured by PFG-NMR (pulsed field gradient-nuclear magnetic resonance) . The result of experiment suggested that the predicting equation for water diffusivity in rice starch/water system could be applied for that in wheat starch (wheat flour) /water system.
