[F1 ANNEX V U.K. DETERMINATION OF THE COMPOSITION AND CONTENT OF STEROLS AND TRITERPENES DIALCOHOLS BY CAPILLARY-COLUMN GAS CHROMATOGRAPHY

Textual Amendments

F1 Substituted by Commission Implementing Regulation (EU) No 1348/2013 of 16 December 2013 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 THE RESULTS U.K.

6.1. Report individual sterol concentrations as mg/kg of fatty material and their sum as ‘total sterols’. U.K.

The composition of each of the individual sterols and of the erythrodiol and uvaol should be expressed to one decimal point.

Total sterol composition must be expressed without any decimal point.

[F2 6.2. Calculate the percentage of each individual sterol from the ratio of the relevant peak area to the total peak area for sterols: U.K.

where:

A _x

=

peak area for x;

ΣA

=

total peak area for sterols.]

Textual Amendments

F2 Substituted by Commission Implementing Regulation (EU) 2015/1833 of 12 October 2015 amending Regulation (EEC) No 2568/91 on the characteristics of olive oil and olive-residue oil and on the relevant methods of analysis.

6.3. Apparent β-sitosterol: Δ5-23-stigmastadienol + clerosterol + β-sitosterol + sitostanol + Δ5-avenasterol + Δ5-24-stigmastadienol. U.K.

6.4. Calculate the percentage of erythrodiol and uvaol: U.K.

where

ΣA

=

sum area for sterol in computing system counts;

Er

=

area of Erythrodiol in computing system counts;

Uv

=

area of Uvaol in computing system counts;]
