Six-panel figure showing detection probability curves for Isoamyl alcohol combined with six different esters: ethyl acetate, ethyl isovalerate, ethyl hexanoate, ethyl caprylate, ethyl nonanoate, and ethyl laurate. Each panel compares measured, theoretical, and fitted detection curves, displaying both theoretical and detected sensory thresholds with correlation values provided for each analysis. Data is shown as log concentration in micrograms per liter on the X-axis and detection probability on the Y-axis. — Sigmoidal threshold modeling for binary mixtures of isoamyl alcohol and fatty acid ethyl esters.
