| Abstract: | Purpose To develop a simple and accurate determination method of the fatty acids in hydrogenated soybean oil.MethodsThe fatty acids fraction of oil was determined after conversion to the corresponding fatty acid methyl esters using boron trifluoride methanol solution 14% by programmed GC.ResultsEight fatty acids in hydrogenated soybean oil can be identified and determined within 20 minutes by this method.The method shows good linearity,precision and recurrence.ConclusionThe method is simple and rapid for the determination of the fatty acids in hydrogenated soybean oil. |
