Is Food Dye Gluten Free?

Yes, food dye is generally considered gluten-free as most commercial food colorings are made from synthetic chemicals or natural sources that do not contain gluten proteins. However, it’s always important to check specific product labels or contact manufacturers directly if you have celiac disease or severe gluten sensitivity, as cross-contamination can occasionally occur during manufacturing processes.
