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.
Other breads & wraps Nomi has checked — these ones aren't ultra-processed.

Yes — Gluten free sourdough loaf by Marks & Spencer is ultra-processed, so it counts as a UPF (ultra-processed food). 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.
Ultra-processed foods (UPFs) are industrial formulations made with ingredients and additives you wouldn't find in a home kitchen — such as emulsifiers, artificial flavourings, colourings and modified starches. The classification is based on the NOVA system used by researchers and dietitians worldwide.
