METHOD OF IDENTIFYING RAPESEED LECITHIN Russian patent published in 2016 - IPC G01N24/08 

FIELD: measurement technology.

SUBSTANCE: invention consists in that is followed by sampling and preparation, sample is taken of lecithin mass (10 ± 0.02) g, preparation of sample is performed by temperature control at temperature of 60 °C for 1 h, after which lecithin sample is placed in pulse sensor of NMR analyser and spin-spin relaxation time is measured first components of lecithin (T₂₁) in milliseconds, lecithin is referred to rapeseed if time of spin-spin relaxation of first components of lecithin (T₂₁) ranges from 158 to 168 ms.

EFFECT: time of identification reduction, avoiding complex preparing sample and avoiding use of organic solvents and toxic chemicals.
