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.
