Gas chromatography e mass spectrometry (GCeMS) analysis
was used to quantify 1-octen-3-ol. The concentration of 1-octen-3-
ol in all samples was compared to ensure volatile concentration was
maintained at similar levels during preparation, thereby removing
concentration differences of aroma volatiles as a variable of
perceivable difference. An equal concentration of 0.8 mL/L 3-
heptanone (SigmaeAldrich, Dorset, UK) was added in dichloromethane to the sample and left on a roller mixer to equilibrate for
