Acetylated starch
What you need to know
Acetylated starch is a modified starch used to keep textures stable through heating and chewing — common in gum and sauces.
“Modified” here means physically/chemically treated starch, not genetically modified.
The body digests it like ordinary starch; regulators consider it very low concern.
Where it stands, by region
The same additive can be approved in one country and banned in another. This is the divergence that matters most.
