METHOD OF DETERMINING CONTENT OF OLEIC ACID IN SUNFLOWER SEED OIL Russian patent published in 2004 - IPC

Abstract RU 2241979 C1

FIELD: fat-and-oil industry.

SUBSTANCE: method comprises preparing samples of seeds for analysis, for which purpose sample is thermostatically held at 23±0.2^оС for 2 h and spin-spin relaxation of oil protons belonging to first component (T₂₁) is measured, after which content of oleic acid P_oa is calculated from formula: P_oa = 1.361 T₂₁ + 213.3.

EFFECT: simplified preparation of sample and shortened analytic time.
