Yes — Light Soy Sauce is ultra-processed.
Not a great choice for everyday use.
This product is ultra-processed because it contains the pre-identified UPF ingredients plain caramel colour, yeast extract powder, and lactic acid as an acidity regulator. These are industrially extracted or formulated additives; yeast extract powder functions as a flavour enhancer, while caramel colour and lactic acid are processing additives. Potassium sorbate is also an industrial preservative. The water, soybeans, wheat flour, salt, and sugar are not the factors driving the classification.
