E1402 – Alkaline treated starch
ThickenerDescription
Modified starch produced by treating starch with alkaline substances like sodium hydroxide or potassium hydroxide
Notes
Alkaline modified starch is regular starch (usually from corn, potato, or wheat) that has been treated with a strong alkali like sodium hydroxide (also known as lye or caustic soda) or potassium hydroxide. This chemical treatment changes the starch's molecular structure, making it behave differently when mixed with water and heated. Think of it as giving ordinary starch a chemical makeover to enhance its performance in food manufacturing. This modified starch works as a thickener, stabilizer, and texture improver in processed foods. You'll commonly find it in sauces, soups, gravies, salad dressings, frozen meals, and baked goods where it helps create the right consistency and prevents ingredients from separating. It's particularly useful because it performs better than regular starch under extreme conditions like high heat, freezing, or acidic environments. While the starting material (starch) is natural, the chemical modification process makes this additive synthetic in nature. It's generally suitable for vegetarians and vegans since it's plant-derived, though those following strict whole-food diets might prefer to avoid chemically modified ingredients. People with celiac disease should check the source of the starch, as wheat-derived versions would contain gluten. The additive is considered safe by food authorities worldwide when used within approved limits.
