[F1 ANNEX XX U.K. Method for the determination of the content of waxes, fatty acid methyl esters and fatty acid ethyl esters by capillary gas chromatography

Textual Amendments

F1 Inserted by Commission Regulation (EU) No 61/2011 of 24 January 2011 amending Regulation (EEC) No 2568/91 on the characteristics of olive oil and olive-residue oil and on the relevant methods of analysis.

6. EXPRESSION OF RESULTS U.K.

Report the sum of the contents of the different waxes from C ₄₀ to C ₄₆ ( Note 7 ) in milligrams per kilograms of fat.

Report the sum of the contents of the methyl esters and ethyl esters from C ₁₆ to C ₁₈ and the total of the two.

Results should be expressed to the nearest mg/kg.

Note 7: The components for quantification refer to the peaks with even carbon numbers amongst the C ₄₀ - C ₄₆ esters, according to the specimen chromatogram of the waxes in olive oil provided in the attached figure. For identification purposes, if the C ₄₆ ester is split, it is recommended to analyse the wax fraction of an olive-pomace oil where the C ₄₆ peak is distinguishable because it is clearly predominant. U.K.

Report the ratio between ethyl esters and methyl esters]
