In the research, carboxymethyl flour was synthesized from
5 varieties of purple rice, including Kum Chao CMU 107, Leum
Pua, Doi Saket, San Kamphaeng, and Huai Hongkhrai, via the
synthesis process registered in the Patent No. 95850 (Figure
2) regarding the production process of carboxymethyl flour from
purple rice . The study revealed that the degree of substitution
2
from all five varieties ranged between 0.3 and 0.45, the quantity
of CMF was at 80-87%, the round-shaped particle size of CMF
ranged from 15 to 30 micrometers (Figure 3), and the amount
of cyanidin-3-glucoside was at 37-226 milligrams per 100
grams. The CMF from Leum Pua rice variety exhibited the
highest anthocyanin content of 226.65 milligrams per 100
grams, while the second highest content was found in Kum
Chao CMU 107, which contained 99 milligrams of anthocyanin
per 100 grams. The synthesized CMF had different hues of
color, from light to deep purple, depending on the concentration
of anthocyanin that remained after the production process.

Carboxymethyl flour (CMF) is a novel modified starch coronary artery disease and cancer, removes toxins and
