Yes — Dark soy sauce is ultra-processed.
Not a great choice for everyday use.
Dark soy sauce is classified as ultra-processed because it contains plain caramel colour and potassium sorbate, which are industrially produced additives used for colouring and preservation. Lactic acid and citric acid are basic acidity regulators and are not the reasons for the classification. Sugar, salt, soybeans, wheat flour, and water are conventional culinary ingredients.
Other sauces, condiments & spreads Nomi has checked — these ones aren't ultra-processed.

Yes — Dark soy sauce by Amoy is ultra-processed, so it counts as a UPF (ultra-processed food). Dark soy sauce is classified as ultra-processed because it contains plain caramel colour and potassium sorbate, which are industrially produced additives used for colouring and preservation. Lactic acid and citric acid are basic acidity regulators and are not the reasons for the classification. Sugar, salt, soybeans, wheat flour, and water are conventional culinary ingredients.
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.
