Yes — Gluten free sourdough loaf is ultra-processed.
Classified as ultra-processed because the ingredient list includes several industrial additives and processed ingredients: humectant glycerol, stabiliser E464 (hydroxypropyl methylcellulose), xanthan gum, fermented maize starch, and golden syrup components in golden milled linseed. These are extracted/modified additives used for texture, moisture retention, and shelf life, which meets NOVA criteria for UPF.
