DyeFreeCheck scans for all 8 petroleum-based synthetic food dyes that the FDA is phasing out by 2027:
We've checked thousands of products across 15 categories. Find dye-free options for everything from snacks to condiments.
Artificial food dyes are petroleum-derived chemicals added to thousands of processed foods to make them look more appealing. Research has linked these synthetic dyes to hyperactivity in children, allergic reactions, and potential long-term health effects.
The FDA announced a voluntary phase-out of synthetic food dyes by 2027, but many products still contain them today. Reading ingredient labels for dye names like “FD&C Red No. 40” or “Tartrazine” can be confusing and time-consuming. A food dye checker like DyeFreeCheck makes it instant: scan the barcode, get a clear answer.
Whether you're a parent avoiding dyes for your kids, managing a dye sensitivity, or simply choosing cleaner food, our food dye scanner helps you make informed decisions at the grocery store.
