# Commission Regulation (EEC) No 2568/91 of 11 July 1991 on the characteristics of olive oil and olive-residue oil and on the relevant methods of analysis, Division 5.5: Quantitative analysis of the waxes

Extent: E+W+S+N.I.

Determine the area of the peaks corresponding to the lauryl arachidate internal standard and the aliphatic esters from C 40 to C 46 with the aid of the integrator.
Determine the total waxes content by adding each individual wax, in mg/kg of fat, as follows:
Waxes, mg ∕ kg = ∑ A x × m s × 1000 A s × m
where:
A x area corresponding to the peak for the individual ester, in computer counts
A s area corresponding to the peak for the lauryl arachidate internal standard, in computer counts
m s mass of the lauryl arachidate internal standard added, in milligrams;
m mass of the sample taken for determination, in grams.
