COMMISSION IMPLEMENTING REGULATION (EU) 2016/1227
of 27 July 2016
amending Regulation (EEC) No 2568/91 on the characteristics of olive oil and olive-residue oil and on the relevant methods of analysis
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EU) No 1308/2013 of the European Parliament and of the Council of 17 December 2013 establishing a common organisation of the markets in agricultural products and repealing Council Regulations (EEC) No 922/72, (EEC) No 234/79, (EC) No 1037/2001 and (EC) No 1234/2007 (1), and in particular point (d) of the first paragraph and the second paragraph of Article 91 thereof,
Whereas:
| (1) | Commission Regulation (EEC) No 2568/91 (2) defines the chemical and organoleptic characteristics of olive and olive-pomace oil and lays down methods of assessing those characteristics. Those methods are regularly updated on the basis of the opinion of chemical experts and in line with the work carried out within the International Olive Council (IOC). |
| (2) | In order to ensure the implementation at Union level of the most recent international standards established by the IOC, the method for the determination of free acidity and the method related to the organoleptic assessment of virgin olive oils set out in Regulation (EEC) No 2568/91 should be updated. |
| (3) | Regulation (EEC) No 2568/91 should therefore be amended accordingly. |
| (4) | The measures provided for in this Regulation are in accordance with the opinion of the Committee for the Common Organisation of the Agricultural Markets, |
HAS ADOPTED THIS REGULATION:
Article 1
Regulation (EEC) No 2568/91 is amended as follows:
| (1) | Annex II is replaced by the text set out in Annex I to this Regulation; |
| (2) | Annex XII is amended in accordance with Annex II to this Regulation. |
Article 2
This Regulation shall enter into force on the seventh day following that of its publication in the Official Journal of the European Union.
This Regulation shall be binding in its entirety and directly applicable in all Member States.
Done at Brussels, 27 July 2016.
For the Commission
The President
Jean-Claude JUNCKER
(1) OJ L 347, 20.12.2013, p. 671.
(2) 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 (OJ L 248, 5.9.1991, p. 1).
ANNEX I
‘ANNEX II
DETERMINATION OF FREE FATTY ACIDS, COLD METHOD
1. SCOPE AND FIELD OF APPLICATION
This method describes the determination of free fatty acids in olive oils and olive pomace oils. The content of free fatty acids is expressed as acidity calculated as the percentage of oleic acid.
2. PRINCIPLE
A sample is dissolved in a mixture of solvents and the free fatty acids present titrated using a potassium hydroxide or sodium hydroxide solution.
3. REAGENTS
All the reagents should be of recognized analytical quality and the water used either distilled or of equivalent purity.
3.1 Diethyl ether; 95 % ethanol (v/v), mixture of equal parts by volume.
Neutralize precisely at the moment of use with the potassium hydroxide solution (3.2), with the addition of 0,3 ml of the phenolphthalein solution (3.3) per 100 ml of mixture.
| Note 1: | Diethyl ether is highly inflammable and may form explosive peroxides. Special care should be taken in its use. |
| Note 2: | If it is not possible to use diethyl ether, a mixture of solvents containing ethanol and toluene may be used. If necessary, ethanol may be replaced by propanol-2. |
3.2 Potassium hydroxide or sodium hydroxide, titrated ethanolic or aqueous solution, c(KOH) [or c(NaOH)] about 0,1 mol/l or, if necessary, c(KOH) [or c(NaOH)] about 0,5 mol/l. Commercial solutions are available.
The exact concentration of potassium hydroxide solution (or sodium hydroxide solution) must be known and checked prior to use. Use a solution prepared at least five days before use and decanted into a brown glass bottle with a rubber stopper. The solution should be colourless or straw coloured.
If phase separation is observed when using aqueous solution of potassium hydroxide (or sodium hydroxide), replace the aqueous solution by an ethanolic solution.
| Note 3: | A stable colourless solution of potassium hydroxide (or sodium hydroxide) may be prepared as follows. Bring to the boil 1 000 ml of ethanol or water with 8 g of potassium hydroxide (or sodium hydroxide) and 0,5 g of aluminium shavings and continue boiling under reflux for one hour. Distil immediately. Dissolve in the distillate the required quantity of potassium hydroxide (or sodium hydroxide). Leave for several days and decant the clear supernatant liquid from the precipitate of potassium carbonate (or sodium carbonate). |
The solution may also be prepared without distillation as follows: to 1 000 ml of ethanol (or water) add 4 ml of aluminium butylate and leave the mixture for several days. Decant the supernatant liquid and dissolve the required quantity of potassium hydroxide (or sodium hydroxide). The solution is ready for use.
3.3 Phenolphthalein, 10 g/l solution in 95 to 96 % ethanol (v/v) or alkali blue 6B or thymolphthalein, 20 g/l solution in 95 to 96 % ethanol (v/v). In the case of strongly coloured oils, alkali blue or thymolphthalein shall be used.
4. APPARATUS
Usual laboratory equipment including:
| 4.1 | Analytical balance; |
| 4.2 | 250 ml conical flask; |
| 4.3 | 10 ml burette class A, graduated in 0,05 ml, or equivalent automatic burette. |
5. PROCEDURE
5.1 Preparation of the test sample
When the sample is cloudy, it should be filtered.
5.2 Test portion
Take a sample depending on the presumed acidity in accordance with the following table:
| Expected acidity (oleic acidity g/100 g) | Mass of sample (g) | Weighing accuracy (g) |
| 0 to 2 | 10 | 0,02 |
| > 2 to 7,5 | 2,5 | 0,01 |
| > 7,5 | 0,5 | 0,001 |
Weigh the sample in the conical flask (4.2).
5.3 Determination
Dissolve the sample (5.2) in 50 to 100 ml of the previously neutralized mixture of diethyl ether and ethanol (3.1).
Titrate while stirring with the 0,1 mol/l solution of potassium hydroxide (or sodium hydroxide) (3.2) (see Note 4) until the indicator changes (the colour of the coloured indicator persists for at least 10 seconds).
| Note 4: | If the quantity of 0,1 mol/l potassium hydroxide (or sodium hydroxide) solution required exceeds 10 ml, use the 0,5 mol/l solution or change the sample mass according to the expected free acidity and the proposed table. |
| Note 5: | If the solution becomes cloudy during titration, add enough of the solvents (3.1) to give a clear solution. |
Carry out a second determination only if the first result is higher than the specified limit for the category of the oil.
6. EXPRESSION OF RESULTS
Acidity as a percentage of oleic acid by weight is equal to:
