Comparative analysis of volatile compounds between jackfruit (Artocarpus heterophyllus L.) peel and its pulp

In the study, the solid-phase microextraction (SPME) and gas chromatography and mass spectrometry (GC-MS) were used for identifying and analysising the volatile compounds of jackfruit (Artocarpus heterophyllus L.) fresh peel (FE) and fresh pulp (FU). The result showed that it was apparent differences of the species and quantities of volatile compounds between peel and pulp. 2,3-Butanediol, Butyrolactone, 1-Methoxy-2-propyl acetate, Butanoic acid, 3-methyl-, butyl ester, n-Amyl isovalerate, n-Hexadecanoic acid were found in peel and pulp. While compounds, such as Geranylgeraniol, Lanosterol, Pentanoic acid, 3-phenylpropyl ester, Phthalic acid, butyl 3-methylbut-2-en-1-yl ester, Hexadecanoic acid, methyl ester, were only present in the peel. But in the pulp, compounds, like Dibutyl phthalate Phenol, 2,4-bis(1,1-dimethylethyl)- henols were confirmed, which did not be found in the peel. The experimental result also indicated that SPME-GC-MS is a simple, rapid, reliable and effective method to analyze the volatile fraction in jackfruit. It may have as profound an impact on analysising the volatile compounds of jackfruit.
