A key feature of rice acceptance by consumers is closely related to its aroma. A few decades of research on rice aroma indicated associated difficulties which arise from its complicated volatile composition. Our investigation seeks to resolve this highly complicated aroma profile using an experimental design for headspace solid-phase microextraction GC–MS. The Plackett–Burman methodology was used as a factor screening method for the headspace solid-phase microextraction procedure and GC–MS analysis, and a central composite design was implemented as an optimization methodology for both steps. Optimization of the extraction procedure and GC–MS analysis leads to a highly resolved rice aroma profile resulting in 66 new constituents. A total of 123 constituents were identified by implementing the procedure on Champa rice from the south of Iran.
