Orange soda is gluten-free — Fanta, Crush, and Sunkist are all GF.
Yes. Orange soda (Fanta, Crush, Sunkist, store brands) is carbonated water, sweetener, citric acid, natural flavors, and color — no gluten-containing grains. The modified food starch is corn-derived (wheat-derived would be allergen-declared). Soda makers follow FDA top-9 allergen labeling and would declare wheat if present. Diet/Zero versions use aspartame/acesulfame potassium, both gluten-free. Fountain orange soda is the same formula as bottled.
Orange soda is a reliably gluten-free pick — whether it’s Fanta, Crush, Sunkist, or a store brand, it’s carbonated water, sweetener, citric acid, citrus flavoring, and color, with no grain. The one ingredient people ask about — “modified food starch” — is corn-derived in US orange soda.
What’s in Orange Soda
Per Fanta’s product information: Fanta Orange is carbonated water, high fructose corn syrup, citric acid, sodium benzoate (preservative), modified food starch, natural flavors, sodium polyphosphates, glycerol ester of rosin, Yellow 6, and Red 40. Crush and Sunkist have similar profiles. Per FDA labeling rules, none of these is a gluten-containing grain.
