The effects of principal extraction conditions on the extraction rates of 10 selected volatile compounds (isoamyl alcohol, ethyl lactate, 2-nonanone, ethyl octanoate, 2-ethyl-1-hexanol, butanoic acid, phenethyl alcohol, phenol, δ-decalactone, and decanoic acid) with the headspace solid-phase microextraction (SPME) method for the analysis of white-brined cheese with two different fibers (CAR/PDMS and DVB/CAR/PDMS) were investigated. Optimum conditions were determined by using response surface methodology (RSM). Results showed that boiling points of volatile compounds significantly affected the effectivity of fibers. CAR/PDMS fiber was more suitable in isolation of the volatile compounds with low boiling point and suggested to be used in the SPME analysis of volatile compounds in white-brined cheese. The optimum condition for CAR/PDMS fiber was found to be as 56.20 °C, 84.92 min, and 549 min−1, for extraction temperature, time, and agitation speed, whereas it was calculated to be as 54.75 °C, 85.60 min, and 250 min−1 for DVB/CAR/PDMS fiber, respectively.
