Olive oil obtained from virgin olive oils by refining methods that do not lead to alterations in the initial glyceridic structure. Its free acidity, expressed as oleic acid, is not more than 0.3 grams per 100 grams. It may be sold directly to the consumer according to the requirements of the country of sale.
