Quick Answer:
Yes, corn syrup is gluten-free. Itโs made from corn, which naturally does not contain gluten. Most commercial corn syrup is safe for those with celiac disease or gluten intolerance, but you should always double-check the label for hidden gluten ingredients or shared equipment warnings.
What Is Corn Syrup?
Corn syrup is a thick liquid sweetener made from corn. Youโll often see it listed as an ingredient in:
- Baked goods (especially pies and cookies)
- Caramel or toffee recipes
- Processed foods
- Store-bought jams and syrups
Unlike high fructose corn syrup (HFCS), which is manufactured for use in packaged foods, regular corn syrup is what youโll find in your grocery store for home baking. Corn syrup helps baked goods retain moisture and stay soft.
