Yes, icing sugar is generally gluten-free.
Icing sugar, also known as confectioners' sugar or powdered sugar, is primarily made from finely ground granulated sugar. The reference provided confirms that certain brands explicitly state their icing sugar is 100% natural and gluten-free. Therefore, in its pure form, icing sugar does not contain gluten.
However, it is crucial to check the packaging of the specific brand you are purchasing. Some icing sugar products may contain added ingredients, such as cornstarch, to prevent clumping. While cornstarch itself is typically gluten-free, there's a risk of cross-contamination during manufacturing, especially if the facility also processes gluten-containing products. If you have celiac disease or a severe gluten intolerance, it's essential to verify that the icing sugar is certified gluten-free to avoid any potential issues.
In summary, while most icing sugar is inherently gluten-free, always read the label and look for a "gluten-free" certification to ensure safety, especially if you have a gluten sensitivity or allergy.
