METHOD OF QUANTITATIVELY DETERMINING LIPIDS IN FOODS Russian patent published in 2005 - IPC

FIELD: analytical methods in food industry.

SUBSTANCE: method comprises providing food sample, adding it to separating funnel with filter, adding extractant, stirring resulting mixture, separating miscella by aspiration from separating funnel, distilling extractant therefrom, removing non-lipid substances from extract lipids, and weighing lipids. Distinguishing feature of invention is that stirring of extract mixture is accomplished via throwing off pressure in separating funnel until pressure provides boiling of extractant, whereupon pressure is returned to its initial value.

EFFECT: increased productivity of examination due to accelerated recovery of lipids and significantly prolonged service time of filter.
