“…The standard deviations showed low dispersion in the composition of the TAG, except for the TAG with 34 carbons, which in general terms, is similar to what was informed by Timms, Pinto et al, Fontecha et al, Gutiérrez et al and Zhou et al [14]- [18]. In Table 1 it is observed that the values of TAG in ultra-pasteurized and raw milk were consistent.…”

The study of the triacylglycerols (TAG) by gas chromatography (GC) using capillary columns is an efficient technique for the determination of some characteristics of quality of fats and oils. The objective of the present study was to determine by GC the content of TAG present in fat of cow and goat milk produced in four zones of Mexico. According to criteria established in Mexican Standardization, 25 samples were obtained of 1 L of ultra-pasteurized cow milk (UHT) and 27 and 48 of raw cow and goat milk, respectively. The fat was extracted from all of the milk samples by detergent solution, and was stored at −20˚C until its analysis. The chromatographic conditions made it possible to identify and quantify TAG of 28 to 54 numbers of carbons, which were analyzed under descriptive and inferential statistical techniques. For the cow milk fat, the statistical analyses indicated significant difference (p < 0.05) in the TAG C34, C50 and C52, and for the goat milk fat in the TAG of C36 to C52. No equality of means was found among the TAG of the cow and goat milk fat. This study offers an advance in the characterization of the TAG present in the cow and goat milk fat produced in Mexico.

“…Contrary to numerous references that have appeared in the older literature, polar solutes such as free glycerol can be analyzed via SFC without derivatization. For example, TAGs have been analyzed by packed column SFC using for example 2-ethylpyridine [9] and silver-ion exchange [10] stationary phases. Using a reversed phase stationary phase such as octadecylsilica [11], the SFC separation may be based upon carbon number (i.e.…”

“…However, the resolution obtained by SFC was not as good as that using highperformance liquid chromatography (HPLC). A completely new approach to the analysis of TAG has therefore been described in the last few years, which represents a "rediscovered" supercritical fluid chromatography, now called Ultraperformance Convergence Chromatography (UPC 2 ) [10].…”
