Considering that a combination of several strategies to compensate for sodium content reduction could be advantageous, we set out to examine whether odour could enhance the saltiness of solutions containing mixtures of sodium and potassium salts in a second experiment.
Moreover, because food usually elicits several tastes that could interact at a perceptual level, we evaluated whether an OISE could be observed in salty-sour solutions containing potassium and sodium salts along with citric acid.
