Fermentation reduces RS content. Flour from sorghum
cv. Tabat was mixed with water and previously fermented
dough starter, and fermented at 37 °C for a maximum of 36 h
showed an increase in the in vitro starch digestibility and a decrease
in the content of RS and total starch (Abd-Elmoneim and
others 2004). RS formation has also been shown to decrease in the
fermented products, idlis and dhoklas.
