The 1 uL of sample was injected in the split mode (20:1) and the hydrocarbons were identified by comparing the retention time and mass spectrum of peaks, as shown in the total ion chromatogram, with that of an authentic standards including 1-tetradecene (C14:1), pentadecane (C15:0), 1 hexadecene (C16:1), 1, 7hexadecadiene (C16:2), heptadecane (C17:0), 8-heptadecene (C17:1), and eicosane (C20:0).
However pentadecane (C15:0) and 1-tetradecene (C14:1) were derived from palmitic acid, with Cn-1 hydrocarbons (C15:0) having higher amounts than Cn-2 (C14:1) (Table 3).
The identified hydrocarbons in all electron beam irradiated beef jerky samples at all doses included pentadecane (C15:0), 1-tetradecene (C14:1), 1,7-hexadecadiene (C16:2), 1-hexadecene (C16:1), 8-heptadecene (C17:1) and heptadecane (C17:0) (Table-4).
The third fatty acid which gave significant amount hydrocarbons by electron beam irradiation was palmitic acid with pentadecane (C15:0) and 1-tetradecene (C14:1) as radiolytic products showing high content in case of Cn-2 than Cn-1.
