The effect of distilled water or brine sample suspensions was examined to measure the effect on headspace composition. According to the report, “The SPME fiber coated with 50/30 μm DVB/CAR-PDMS afforded the highest extraction efficiency, particularly when the samples were extracted at 60°C for 15 min under dry conditions with toluene as an internal standard.” The authors extracted and identified 45 compounds, dominated by previously known odoractive components. The authors reported that their cocoa product analysis was remarkably reproducible and sensitive, and that more research of the chocolate making process is underway to further analyze flavor/odor volatile compounds.
