ANNEX VDETERMINATION OF THE COMPOSITION AND CONTENT OF STEROLS BY CAPILLARY-COLUMN GAS CHROMATOGRAPHY

6.EXPRESSION OF THE RESULTS

6.1

Record individual sterol concentrations as mg/100 g of fatty material and their sum as ‘total sterols’.

6.2

Calculate the percentage of each individual sterol from the ratio of the relevant peak area to the total peak area for sterols.

% of sterol x = AxA · 100math

where:

Ax

peak area for x;

A

total peak area for sterols.
