METHOD FOR DETERMINATION OF LINOLENIC ACID CONTENT IN LINESEED Russian patent published in 2005 - IPC

Abstract RU 2260794 C1

FIELD: fat-and-oil industry.

SUBSTANCE: claimed method includes linseed sample preparation for analysis and linolenic acid content calculation in percents. Lineseed sample preparation is carried out by incubation thereof at 23±0.2°C for 2 h followed by measurement of oil proton spin-spin NMR relaxation characteristics and calculation of weighted average value of spin-spin relaxation time (T_2WA, in msec) and linoleic acid content (P_lin in %) is calculated according to formula: P_lin = 1.277T_2WA-92.081.

EFFECT: accelerated measurement method, simplified sample preparation.
