Acetylated distarch adipate

Acetylated distarch adipate introduces two types of modification simultaneously: acetyl groups (reducing retrogradation and improving freeze-thaw stability) and adipate cross-links formed using adipic acid, a dicarboxylic acid found naturally in beetroot juice. The cross-links improve heat stability and resistance to mechanical shear. Together these modifications make E1422 well suited to canned products, retort-processed soups, salad dressings, and frozen desserts requiring both heat resistance and smooth texture on thawing.

JECFA evaluated acetylated distarch adipate in 1981 and did not establish a numerical ADI. Both the acetate and adipate modifications are present at low regulated substitution levels. They are metabolised through normal pathways — acetic acid and adipic acid are both normal dietary and metabolic compounds.

Acetylated distarch adipate is approved in the EU (E1422), the United States (GRAS), and globally. It is a common ingredient in commercially produced salad dressings and retort-packaged sauces in the United States and Asia-Pacific markets. Gluten source considerations apply as with other wheat-derived modified starches. No adverse health effects have been identified at dietary intake levels.
