Fatty acid analysis by hplc abstract: although gas chromatography is the predominant technique used for fatty acid analysis, high-performance liquid chromatography has an important role to play in applications such as the handling of less usual samples, avoidance of degradation of heat-sensitive functional groups, and for micropreparative purposes. Branch chain fatty acids, while actinomycetes produce 10-methyl fatty acids one can categorize the results by the type of organism generating the fatty acids found.
Physicochemical characterization, fatty acid composition, the analytical tests for the characterization of the oil were performed at the laboratory for research and analysis of fuels, chemistry department and drugs quality control laboratory, faculty of pharmacy, federal university of pará, ufpa, from march to december 2010. The acid content of edible fats is given by the quantity of free fatty acids deriving from the hydrolytic rancidity of triglycerides as this alteration occurs in unsuitable conditions for the processing and preservation of fats, acidity represents a basic indicator of the genuineness of the product. Figure 3 is the xic of fatty acids found in sample a table 2 shows the analysis results for the six samples in figure 3, there were lots of unknown peaks in the late elution stage on many of the xics.
