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
