According to obtained micrographs presented in Fig. 4(a), (b) and
(c) the structure was consisted presumably of small densely packed
rice starch granules incorporated in interrupted protein and CMC
matrix.
The starch granules were intact in spite the thermal treatment
due to insufficient amount of added water in all of the used cookie
formulations. Moreover, micrograph of wheat flour‐based cookie
(Fig. 4(d)) showed, as it was expected, much larger starch granules
in comparison to rice starch granules
