What is it about?
In literature are reported procedures for triglyceride transesterification as mathyl, ethyl, propyl, butyl esters of fatty acids analyzed by GC. In this paper a new transesterification procedure based on fatty acid pentyl esters is reported. The adavntage of this procedure is that pentyl butanoate is not miscible with water and has higher boiling point than butyl pentanoate and then is better analyzed by GC. Moreove another transesterificatio procedure of triglycerides in reported based on formation of fatty acid phenetyl esters that were separated by using liquid chromatography (HPLC) and detected by means of UV detector.

Why is it important?
This paper is important because gives the possibility to analyse fatty acid chains linked in triglycerides in the best way, by using the same GC capillary column used for separation of fatty acid methyl esters. As an alternative, this paper gives to analysts the possibility to analyze triglicerides mixtures (butteroil, olive oil etc.) in liquid chromatography (HPLC).
Perspectives
I think that this paper can change the way of analysing triglycerides mixture applying two new transesterification procedures: fatty acid pentyl esters and phenetyl esters. These new procedures are an alternative to fatty acid methyl esters and to procedures that use post column derivatization for HPLC analysis of fatty acids.
