Does corn starch have gluten?
Corn starch, also spelled as cornstarch and known as maize starch, tends to be a white powder and a common additive in food. Its main purpose is usually to act as a thickener in recipes, so it is popular in gravy, sauces and puddings. Corn does not have the gluten protein in it, but this does not mean that all brands of corn starch are safe for those on a gluten-free diet.
It is possible for cross-contamination to occur during the manufacturing process, and some brands add extra ingredients that can make corn starch unsafe. Pure corn starch does not have gluten, but you must check each brand before you buy it.

What is modified corn starch?
You will frequently see modified corn starch on ingredient labels, and it means that the starch has been changed with chemicals or enzymes. It is also used as a thickener or stabilizer in recipes. Modified corn starch is common in packaged and processed foods because it can often withstand temperature changes. Similar to plain corn starch, it is important to check the labels and make sure it is gluten-free, but it is generally safe.
