Sažetak
It is known that triglycerides comprise 97-98% of the total milk lipids. Composition of milk fat triglycerides i.e. the percentage of individual fatty acids in them are effected by the species, as well as by the breeding, composition and plan of feeding, lactation, season, climate and agitation. Determinations of triglyceride composition of milk fats have been carried out by high-temperature gas chromatography. Great number of samples of cow and sheep milk fats have been analyzed. Separation of triglycerides proved to he satisfactory according to the number of carbon atoms in acyl chain of triglycerides. The obtained quality of separation is also proved by the fact that even triglycerides with an odd number of carbon atoms have been separated. Comparison of gas chromatograms of the composition of triglycerides from different samples of milk fat can give the data on the origin, quality and possible addition of vegetable oil or animal fat, particularly if the addition exceeds 10%.
