E1400 – Dextrins, roasted starch
ThickenerDescription
White to yellow-white powder or granules, produced by heat treatment of starch in the presence of acid or alkali catalysts
Notes
Dextrin is created by breaking down starch (usually from corn, wheat, or potatoes) using heat treatment combined with small amounts of acid or alkali (a basic substance, the opposite of acid). Think of it as a controlled way of partially 'cooking' starch to change its properties - similar to how toasting bread changes its texture and behaviour. During this process, the long starch molecules are broken into shorter chains, creating a powder that behaves differently from regular starch when mixed with water. Dextrin serves multiple functions in food production, primarily as a thickening agent, stabilizer, and binding agent. You'll encounter it in powdered soups, instant gravies, salad dressings, processed meats, baked goods, and adhesive substances (like the glue on stamps and envelopes, though that's obviously not food-grade). In foods, it helps create the right texture, prevents ingredients from separating, and can help bind mixtures together while being easier to dissolve than regular starch. Since dextrin comes from plant starches, it's naturally suitable for vegetarians and vegans. However, people with celiac disease or gluten sensitivity should check the source - if it's made from wheat starch, it could potentially contain traces of gluten, though the processing often removes most gluten proteins. Dextrin made from corn or potato starch is typically gluten-free. It's considered very safe and is widely used in both conventional and organic food production.
