Acetylated distarch phosphate

Acetylated distarch phosphate combines two chemical modifications: phosphate cross-linking (as in E1412, improving heat and acid stability) and acetylation, in which acetyl groups are introduced at hydroxyl positions of the starch chain. Acetylation reduces retrogradation — the stiffening and syneresis that occurs when starch gels are frozen and thawed — making E1414 particularly suited to frozen ready meals, sauces, and products requiring a smooth, stable texture across freezing and reheating cycles.

JECFA evaluated acetylated distarch phosphate in 1981 and did not establish a numerical ADI. Digestibility is equivalent to native starch. Acetate groups introduced during modification are cleaved during digestion to acetic acid, a normal cellular metabolite present in every fermented food.

Acetylated distarch phosphate is approved in the EU (E1414), the United States (GRAS), and globally. It is a standard ingredient in commercially frozen meals, sauces, and soups where consistent texture after reheating is essential. Gluten source verification applies as with E1412 — wheat-derived versions may be unsuitable for coeliacs or wheat-sensitive consumers. No adverse health effects are documented at typical dietary intake.
