# 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 4.5.4: Normalisation of fatty acid moles to 100 % (2)

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

moles % P 1,2,3 = moles P * 100 moles P + S + Po + O + L + Ln
moles % S 1,2,3 = moles S * 100 moles P + S + Po + O + L + Ln
moles % Po 1,2,3 = moles Po * 100 moles P + S + Po + O + L + Ln
moles % O 1,2,3 = moles O * 100 moles P + S + Po + O + L + Ln
moles % L 1,2,3 = moles L * 100 moles P + S + Po + O + L + Ln
moles % Ln 1,2,3 = moles Ln * 100 moles P + S + Po + O + L + Ln
The result gives the percentage of each fatty acid in moles % in the overall (1, 2, 3–) position of the TAGs.
Then the sum of the saturated fatty acids P and S (SFA) and the unsaturated fatty acids Po, O, L and Ln (UFA) are calculated (3):
moles % SFA = moles % P + moles % S
moles % UFA = 100 − moles % SFA
