E1423 — Acetylated distarch glycerol
Why it’s used
A starch cross-linked through a glycerol bridge (via epichlorohydrin treatment) and then acetylated, producing a thickener with stable viscosity through cooking, cooling, and freeze-thaw cycles; used in sauces, dairy desserts, and other processed foods that need shear-resistant texture.

Regulatory status
Permitted as 'food starch-modified' under 21 CFR 172.892, which authorizes both epichlorohydrin (glycerol cross-linking, up to 0.3%) and acetic anhydride (acetylation) as treating agents for food-grade modified starch. Source (2026-07-24)
Not part of the EU's harmonised list of modified starches authorised under Regulation (EC) No 1333/2008 Annex II/III, which covers only E1404, E1410, E1412-E1414, E1420, E1422, E1440, E1442, and E1450-E1452 (confirmed by EFSA's 2017 group re-evaluation opinion, which names exactly those 12 substances as the EU-authorised set).

Regulatory status by region
The FDA regulates modified starches generically under 21 CFR 172.892 by permitted reagent (here, epichlorohydrin for the glycerol cross-link plus acetic anhydride for acetylation) rather than by individual Codex/INS number, so this compound is allowed. The EU instead authorizes modified starches by name on a fixed list, and this specific INS-designated starch was never added to that list, so it has no lawful use as a food additive in the EU even though it carries a recognized E-number.
The EU authorises only 12 specific modified starches under Regulation (EC) No 1333/2008 (E1404, E1410, E1412-E1414, E1420, E1422, E1440, E1442, E1450-E1452). This Codex/INS-recognised starch was not carried into that harmonised list, so it cannot legally be used as a food additive in the EU, unlike the US which permits it generically by reagent under 21 CFR 172.892.
