Yes — Brown Sauce is ultra-processed.
The ingredient list is valid. The product is ultra-processed because it contains modified maize starch, which is an industrially processed additive used as a thickener/stabilizer and is classified as UPF under NOVA. Other ingredients like sugar, vinegars, cane molasses, date purée, tomato purée, tamarind, salt, and spices are not UPF by themselves, but the presence of modified maize starch is sufficient to classify the overall product as ultra-processed.
Other sauces, condiments & spreads Nomi has checked — these ones aren't ultra-processed.

Yes — Brown Sauce by By sainsbury's is ultra-processed, so it counts as a UPF (ultra-processed food). The ingredient list is valid. The product is ultra-processed because it contains modified maize starch, which is an industrially processed additive used as a thickener/stabilizer and is classified as UPF under NOVA.

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.
