“…Therefore, modification of rice starch based on physical, chemical, and biological reactions has been suggested to solve this problem (18). In the present study, chemical modification based on carboxymethylated etherification was used because the modified starches obtained from this etherification reaction were reported to cover a wide range of applications including pharmaceutical and biomedical fields (19). The color of the obtained modified rice powders of the four varieties was off-white while that of the color of the original raw rice powders was pure white.…”
