Some unidentified minor compounds have been observed in the residue from short‐path distillation of transesterified palm oil that are not detected in the original palm oil. A method combining short‐path distillation to enrich the unknowns with fractionation using solid‐phase extraction is described. The fractionated components were identified using GC coupled with MS. The transesterified palm oil was found to contain methyl esters of up to C 32 carbon atoms. In the very long chain FAME with carbon numbers ≥20, both even and odd carbon numbers accounted for 0.26 wt%, with C 24 and C 26 being the major ones present in the residue after short‐path distillation of transesterified palm oil.
