Outline of Final Research Achievements

During cooking of noodle, starch gelatinization is preceded at the surface of the noodle strain because of its water rich environment. Since the water holding capacity (WHC) of starchy food depends on the degree of starch gelatinization, the surface regions of the noodle hold the most water. Consequently, it is not easy for water to migrate from the exterior to the interior of the noodle. If the excessive increasing of WHC at surface region of noodle could be suppressed, water migration to the inside of the noodle might be promoted. Moreover, it is expected that the surface WHC is strongly affected by the flow during cooking. Although it is said that the flow condition may affect the cooking of noodles, the quantitative evaluation of flow effect is scarcely. Our objective is to clarify the effect of flow on the water migration in starchy food during cooking.
