So far fragrance of rice has mainly been determined by the traditional sensory method. This evaluation is fast but does not define precisely because it depends entirely on subjective assessment of the evaluator’s olfaction. To overcome this shortcoming, the modern physico-chemical methods, SDE-GCFID and SDE-GCMS were employed. In these analytical processes, quantitative analysis of 2-AP content in pandan’s leaf was performed to serve as basis for comparison with that in aromatic rice. By these methods, since 2005, 2-AP and some other aromatic compounds in aromatic rice have been identified and quantified in thePhysicochemicalLaboratory, Centerfor Biological and Chemical analysis and experiment,University of Agriculture andForestryHo Chi Minh City. In this laboratory from 2010,the content of2-APin theold, matureand young leaves of Pandanus were accurately quantified andused asa standardforquantification of2-AP infragrant rice usingSDE(orSPME)extraction methodcombinedwithGC-FID and GC-MS. The limit of detection(LOD) andlimit of quantification(LOQ) ofthemethod were also determined.
