FIELD: analytical methods in fat-and-oil industry.
SUBSTANCE: method comprises sampling vegetable oil, measuring conductivity value of sample under direct current conditions, calculating phospholipid content according to formula and using calibration curve plotted in coordinates "phospholipid content' versus "conductivity value". Conductivity is measured at 45 to 250°C. Invention allows more accurate values to be obtained and carrying out determination at process temperatures, i.e. enables in-line control of phospholipid weight content "in stream" immediately before and after process conducted.
EFFECT: increased determination accuracy and enabled its use in automatic control systems.
