A gas chromatographic procedure for analysis of sterols was developed to detect possible addition of vegetable oils to milk, yoghurt and butter samples. The method involved fat extraction, saponification, hexane extraction, silylation of sterols and then analysis by gas chromatography. The sterol content of 102 samples of milk, yoghurt and butter was determined. Phytosterol content higher than 5% of total sterol was observed in four samples of milk and yoghurt. Principal component analysis showed that there was a direct relationship between the level of phytosterols and fat percentage in yoghurt samples. The described method is accurate and reliable enough to be employed regularly in food quality laboratories.

“…Analysis of TAGs constitutes a challenge for the analyst due to the large number of TAGs molecular species that can be derived from the common, naturally occurring fatty acyl groups found in biological sources. Consequently, more effort has focused on the separation and determination of molecular species of TAGs than to any other single-lipid class (Lipp 1995).…”

The composition of triacylglycerols (TAGs) is a very useful parameter to understand several properties of creams and anhydrous milk fat products such as nutritional value, technological applications, and textural properties. In this paper, the molecular species of TAGs of equine milk were identified using a combination of nonaqueous reversed phase high-performance liquid chromatography, electrospray ionization mass spectrometry and high temperature gas chromatography and were then compared to the TAGs composition of human milk. The data showed that equine milk contained a complex mixture of different TAGs molecular species resulting from the widest range of its fatty acids as compared to human milk. In particular, the largest differences in TAGs composition between equine and human milk concerned TAGs containing medium-chain fatty acids; for C 8 ,C 10 ,a n dC 12 . In terms of carbon number (CN), TAGs with CN36-CN46 were the most abundant in equine milk with a maximum concentration at CN44 (15.3%), while TAGs with CN44-CN52 were the predominant in human milk with a maximum of CN52 (30%). For both milks studied, the experimentally determined distributions of TAGs molecular species deviated from those predicted by the random hypothesis. TAGs with CN44 corresponding to a fatty acids carbon number distribution of C 8 /C 18 /C 18 ,C 12 /C 14 /C 18 ,a n dC 10 /C 16 /C 18 were apparently preferentially synthesized in equine milk. Whereas, in human milk, mixed TAGs with CN52 containing C 16 /C 18 / C 18 fatty acids were much higher than would be expected from the random calculation.

“…All of them reported that the distribution of fatty acids in the triacylglycerol molecule was not random, having a high degree of asymmetry [6,. Reversed-phase, high-performance liquid chromatography (RP-LC) is perhaps the most widely used technique tO separate triacylglycerol mixtures [12][13][14]. Complex fat mixtures, such as dairy fat, which contain a very large number of different fatty acids, require special attention in the separation and identification of triacylglycerols due to the variety of molecular species present.…”

Determination of triacylglycerol composition of idiazabal cheese

et al. 1998

SummaryTriacylglycerols from Idiazabal cheese fat were analysed by high-performance liquid chromatography (LC) with a non-linear gradient of acetone in acetonitrile and a light-scattering detector. Molecular species of triacylglycerols were predicted by a simple and a multiple linear regression analysis of log k of the LC peaks and molecular variables such as equivalent carbon number of the possible triacylglycerol, chain length and number of double bonds of each fatty acid of the triacylglycerol. Predicted results were confirmed by gas chromatographic analysis of the fatty acids in the LC peaks. The main triacylglycerols of Idiazabal cheese fat contained butyric acid, butyroyl-dipalmitin, butyroyl-myristoylpalmitin and butyroyl-palmitoyl-olein. The most abundant triacylglycerols were those with even partition numbers of 36, 34 and 38.
