Comparing E525 - Potassium hydroxide vs E1402 - Alkaline modified starch

Overview

E525 - Potassium hydroxide

Potassium hydroxide (E525) is a strong alkaline ingredient used to control acidity in foods. In tiny, carefully measured amounts it helps keep products stable in taste, color, and texture, and it can also be used to help peel some fruits and vegetables during processing. It’s sometimes listed on labels as potassium hydroxide or E525.

E1402 - Alkaline modified starch

Alkaline modified starch (E1402) is a form of food starch that has been treated with a mild alkali to improve its cooking and storage performance. It helps foods stay smooth and stable, especially in sauces, soups, and ready meals. It is one of several “modified starches” approved for use in many countries.

Popular questions

  1. Is potassium hydroxide a strong base?

    Yes—potassium hydroxide (KOH) is a prototypical strong base that fully dissociates in water and is highly caustic in concentrated form.

  2. What is potassium hydroxide used for?

    In foods (E525) it’s used as an acidity/pH regulator and processing aid, e.g., for lye peeling of fruits and vegetables, curing olives, and in some cocoa and caramel color processing.

  3. Is potassium hydroxide safe?

    Yes—at permitted food-use levels it’s considered safe (GRAS in the U.S. and authorized in the EU); concentrated solutions are corrosive and must be handled carefully.

  4. What is the formula for potassium hydroxide?

    KOH.
