Dextrinated Rice Flour
Dextrinated rice flour is a modified starch ingredient with no inherent toxicological concerns. As with other rice-derived ingredients, trace inorganic arsenic levels are relevant primarily for infant foods, and FDA has issued action levels and guidance.
What it is
Rice flour that has been heat- and/or acid-treated to partially hydrolyze starch into shorter dextrins, improving solubility and digestibility.
Texturizer, thickener, and bulking agent in infant foods, gluten-free formulations, and snacks.
Why it's flagged
- trace inorganic arsenic (rice-based)
- rapidly digestible starch / glycemic load
What regulators actually say
"Dextrin is a polymer of D-glucose units that is produced from starch or starch-containing substances by heat alone or by treatment with food-grade acids."
"FDA has set an action level of 100 parts per billion (ppb) of inorganic arsenic in infant rice cereal."
