Yes — English Mustard is ultra-processed.
The product is classified as ultra-processed because it contains xanthan gum, an industrial stabiliser, which falls under emulsifiers/stabilisers in the NOVA system. All other ingredients (water, mustard flour, sugar, spirit vinegar, salt, fortified wheat flour, turmeric powder) are minimally processed or basic culinary ingredients and do not by themselves make the product UPF, but the presence of xanthan gum is sufficient to classify it as UPF.
Other sauces, condiments & spreads Nomi has checked — these ones aren't ultra-processed.

Yes — English Mustard by Tesco is ultra-processed, so it counts as a UPF (ultra-processed food). The product is classified as ultra-processed because it contains xanthan gum, an industrial stabiliser, which falls under emulsifiers/stabilisers in the NOVA system. All other ingredients (water, mustard flour, sugar, spirit vinegar, salt, fortified wheat flour, turmeric powder) are minimally processed or basic culinary ingredients and do not by themselves make the product UPF, but the presence of xanthan gum is sufficient to classify it as 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.
