WebEsters, aldehydes, alcohols and sulfur compounds have been found to be the main aroma components in strawberry. In recent years, two volatile compounds, 2,5-dimethyl-4-methoxy-3(2H)-furanone (DMF) and 2,5-dimethyl-4-hydroxy-3(2H)-furanone (DHF) were reported to contribute heavily to strawberry aroma. Webas GC/MS, GC/ECD, or GC/NPD, proved that quantification limits of previous methods could be reduced 5-fold to approximately 10 ppb for an incurred pesticide sample. Water was introduced as an integral part of the initial extraction to facilitate SPE loading, but it also had additional benefits. Water partitioning enables the more polar set of
