Parameters extracted from time-intensity (TI) curves for perceived saltiness (mean ± standard error) which showed significant differences between samples. Values in the same row with different letters are significantly different (p < 0.05).

Samples: FMS = foam-mat salt; RS = regular salt. Time-intensity parameters: Imax = maximum perceived sensory saltiness; Rate Imax = the maximum perceived saltiness over time to Imax; T(Last Max) = time to last highest perceived saltiness value; T(Last 50% Max) = time taken to reach 50% of maximum perceived saltiness; Max. Duration = time at maximum intensity; T Start (90% Max) = time taken to reach the first 90% of maximum perceived saltiness; T Stop (90% Max) = time taken to reach 90% of maximum perceived saltiness on the descent slope of TI curve; AUCsensory = area under the curve of the TI curve; Desc. Area. = the area of the declining slope of the TI curve.
