In recent decades, Russia has increased the demand for
high oleic sunflower oil and, consequently, for the raw
material from which it is derived – high oleic sunflower
seeds. Currently existing methods of control of mass
fraction of oleic acid in the seed oil of sunflower, have
significant drawbacks, due to which sharply raises the
question of the development of the Express methods of
control of mass fraction of oleic acid. The study presents
the results of determining the mass fraction of oleic acid
in the oil of sunflower seeds, obtained by known
methods (GC and ri), and developed a method based on
NMR. The developed method of determining the mass
fraction of oleic acid in sunflower seed oil has a number
of advantages compared with the known: is not
destructive (does not require the extraction of oil from
seeds), does not require special sample preparation
excludes the use of toxic chemicals, the analysis duration is 5 minutes, ensuring high representativeness of the
sample, and the simplicity and automation of the analysis
process reduces the requirements for qualifications of
laboratory personnel. The developed method of
determining the mass fraction of oleic acid in the oil of
sunflower seeds can be carried out simultaneously with
the determination of oil and moisture content of seeds on
commercially available analyzers, but I hope it 1006М,
which is currently applied at more than 250 companies of
oil and fat industry
