6. EXPRESSION OF RESULTS U.K.

Indicate the total of the contents of the various C ₄₀ to C ₄₆ waxes in mg/kg fat (ppm).

NB : The components to be quantified refer to the peaks with carbon pair numbers between esters C ₄₀ and C ₄₆ , using the example of the olive oil wax chromatogram shown in the figure below. If ester C ₄₆ appears twice, it is recommended that to identify it the fraction of the waxes of an olive-residue oil should be analysed where the C ₄₆ peak is easy to identify because it is in the clear majority. U.K.

The results should be expressed to one decimal place.
