What is E1422?
A modified starch made from ordinary starch, such as maize, potato or tapioca starch. The starch is cross-linked with adipic anhydride and treated with acetic anhydride. This makes it hold its thickness better under heat, acid and stirring than plain starch.
Why it's marked “Generally halal”
The base is plant starch and the reagents are industrial chemicals, so no animal material or alcohol is involved. The word “acetylated” refers to acetic acid, the acid in vinegar, not to alcohol. There is no known halal catch.
How to check the label
No special check is needed for this starch. A thickened product may still contain gelatin or other doubtful ingredients, so read the rest of the label.
Where you'll find it
- sauces and ketchup
- dairy desserts
- soups
- ready meals
- fruit fillings
Good to know
- EFSA's 2017 re-evaluation of 12 modified starches found no safety concern and no need for a numerical acceptable daily intake.
- Modified starches are not absorbed intact: gut enzymes break most of them down and gut bacteria ferment the rest.
