The preparation of the fatty acid methyl esters from olive oils and olive-pomace oils are performed by transesterification with methanolic solution of potassium hydroxide at room temperature. The necessity of purification of the sample prior to the trans-esterification depends on the sample's free fatty acids content and the analytical parameter to be determined, it can be chosen according to the following table:
| Category of oil | Method |
|---|---|
| Virgin olive oil with acidity ≤ 2,0 % |
|
| Refined olive oil | |
