Volatile organic compounds (VOC) in fresh Capsicum annuum (FRC), red pepper flakes (RPF), industrial (INI), and traditional (TRI) isot spices were quantitatively analyzed by means of solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry (GC-MS). Total concentration of VOC in FRC, TRI, RPF and INI were 23.24, 113.24, 15.29 and 28.48 mg kg−1 dry weight, respectively. VOC characteristics of RPF and FRC were similar compared to isot. The production method of TRI was noticed to be appropriate for enzymatic and/or thermally degradations of terpenoids, carotenoid, amino acids, lipid derivatives, and some Strecker degradations compounds. Heat induced or thermally generated by Maillard reactions or Strecker degradations were responsible for the diversity of INI due to heating and kepertme thermal process. The results show that the mild thermal process, suitable moisture content and time were critical parameters for the total amount and diverse patterns of VOC during production of pepper spice from capsicum anuum.
