Description
To determine the mass fraction of linolenic acid in flax seed oil the authors developed a rapid method based on the pulse method of nuclear magnetic resonance with the use of NMR analyzers low resolution. This method has some significant advantages compared with the known method on the basis of chromatographic method for the determination of the mass fraction of linolenic acid in the oil extracted from the seeds of flax, namely, does not require additional sample preparation (extracting oil by solvent), eliminates the use of toxic chemicals, requires a much lower investment of time to conduct a single analysis, highly automated, and eliminates the influence of human factor on the research results. The method is based on the revealed correlation between the weighted average time spin-spin relaxation of protons contained in the triacylglycerols of the oil of the flax seed, and a mass fraction of linolenic acid in the seed oil at a temperature of 23ºc. In article results of research of influence of temperature on the weighted average time spin-spin relaxation of protons contained in the flax seed oil. Installed directly proportional linear relationship between the temperature of flax seeds and measured the average time spin-spin relaxation of protons oil contained in the flax seeds with the correlation coefficient is 0,930, the temperature change of the sample of seeds at 1 ° C leads to the change of the coefficient is 0.011 kt. The developed methodaccuracy in the temperature range from 20 to 26 ºC
