Les huiles végétales

Par Christian Bauer, Ingénieur, naturopathe, thérapeute

L’une des choses primordiales afin de consommer des huiles de qualité est de les acheter biologiques et de première pression à froid. – De qualité biologique pour éviter d’ingérer des pesticides et des OGM par exemple.
– De première pression à froid car une huile chauffée et raffinée (le but de ces procédés étant uniquement d’augmenter le rendement au détriment de la qualité) perd une grande partie de ses propriétés : les fragiles doubles liaisons dont nous avons parlé se rompent à la chaleur, le raffinage utilise de nombreux solvants chimiques.

De manière générale, il vaut mieux éviter de chauffer les huiles. Plus ces huiles contiennent d’AGPI, plus elles sont fragiles (comme les huiles de noix, de maïs ou de soja). A température relativement basse, il est possible de chauffer des huiles comme l’huile d’olive, celle d’arachide voire celle de tournesol. Pour les fritures, il faut préférer l’huile de palme. Dans tous les cas, attention à ne pas surchauffer l’huile, à la renouveler fréquemment et aussi à la filtrer des particules noires qui restent présentes après chauffage.Entre parenthèses et pour démystifier un peu tous ces termes pseudo-scientifiques (oméga 3, 6, 9), ces appellations ne correspondent en fait qu’à la localisation de la première double liaison carbone-carbone au sein de la molécule. C’est-à-dire que si c’est à partir du 3e carbone qu’il y a une double liaison, la molécule sera appelée oméga 3. C’est en réalité un peu plus compliqué que cela, mais cela ne reste ni plus ni moins qu’une méthode de classification sans plus d’intérêt.

Les huiles sont aussi sensibles à la lumière et à l’oxygène. Il est donc conseillé de les stocker à l’abri de la lumière et de refermer le bouchon. Ce n’est pas un hasard si les fabricants utilisent des flacons en verre teinté assez sombre (éviter le plastique !). Certains poussent le perfectionnisme jusqu’à mettre les huiles au froid pour diminuer encore l’effet oxydatif. Pourquoi pas ? Il faut simplement savoir que les points de solidification des huiles sont très proches des températures ambiantes et qu’à basse température des cristaux solides peuvent se former. L’huile de palme, par exemple, est vendue en pain solide à température ambiante.

Voyons maintenant les principales propriétés des huiles les plus courantes.

L’huile d’olive
C’est sans doute l’huile la plus médiatiquement réputée en terme de santé. Cependant, elle ne contient que peu des fameux AGPI (acides gras poly-insaturés oméga 3 et 6). Elle contient surtout de l’acide oléique ou encore oméga 9 qui est mono-insaturé (une seule double liaison carbone-carbone) et qui supporte donc mieux la cuisson. Il existe plusieurs qualités d’huile d’olive : huile d’olive vierge extra (ne pas chauffer), huile d’olive vierge extra fruitée, huile d’olive vierge extra douce. Elle contient les vitamines A, D, E et K, joue un rôle non négligeable à de nombreux niveaux notamment artériel, hépatique, rénal, digestif, cutané.

Pilot plant to treat olive vegetable water

The Environment Ministry will establish a pilot plant by the end of this year to treat the liquid residue of the olive-pressing process, as it pollutes the soil and water resources.

The JD500,000 EU-funded plant, to be built either at the Ikeider holding area or the Jordan University of Science and Technology, will start operating within four to six months with a daily capacity of 5-10 cubic metres, according to Adnan Khdair, director of integrated waste management of the Olive Oil Pressing Industries Programme.

The programme was launched in 2005 to introduce elements of an integrated waste management system to the olive oil sector in Jordan, Lebanon and Syria.

Khdair said the plant will help curb the environmental problems caused by olive vegetable water (OVW), which contains large quantities of organic matter, solid material and oil that are hard to treat.

The country’s 105 olive mills produce 200,000 cubic metres of OVW annually, which poses an environmental challenge, he said.

“The ministry decided to establish the plant as studies indicate that OVW harms the environment as it contains chemicals,” Khdair said, adding that the plant is part of the ministry’s measures to address environmental problems resulting from the by-products of olive presses.

Global warming ravages olive harvest

By Gözde Aslantaþ,

The olive orchards in the Bergama-Dikili-Zeytindað triangle, including some parts of Ayvalýk, have caused concern with about 40 percent loss in harvest. Discussing the definition of “natural disaster” at the “Olive and Bergama” panel discussion within the scope of the 71st International Bergama Festival, the producers asked for urgent action for putting into practice the “natural disasters law.”

Northern Aegean olive oil producers gathered at the “Olive and Bergama” panel discussion to hear the opinions of experts and learn the steps they have to take. At the panel, asking for the loss to be compensated, they informed the mayor and the head official of the district about their request. The producers expressed that they wanted to make use of the “natural disasters law.”

Within the scope of the law, if the fixed rate of loss due to a natural disaster is 40 percent or above, agriculture directorates should prepare the necessary reports to cover the relevant loss after controlling and fixing the rates. Thus, the farmers can make use of bank credits and convenient payment schemes.

After listening to the complaints of the farmers throughout the panel discussion, Ersezgin Companies Group Food Department Head Naci Özgen said: “This loss is completely due to global warming which by nature is a ‘natural disaster’. Therefore, I can say that their complaints and requests are timely and fitting.”

“The reasons are the excessive regression of underground waters, changing climates and extreme heat. Yet the final stroke was the desert dust that came with the rain at the end of May which seriously damaged the olive trees in the blossoming period that had negative effects on the fruits,” added Özgen.

Castelas: Couple makes award-winning olive oil

By Leah Larkin,

He carefully pours a small quantity of the liquid from the dark green bottle into a tiny spoon, lifts the spoon to his nose and sniffs the contents.

“It smells of fresh-cut grass,” he proclaims. He then moves the spoon to his mouth and inhales, letting the juice roll around in his mouth before swallowing. The taste, he says, is reminiscent of “artichokes, almonds, with a pepperiness…. It’s long on the palate.”

Jean-Benoit Hugues was not tasting wine. He was talking about his olive oil, Castelas Huile d’Olive A.O.C. de la Vallée des Baux de Provence, a premier olive oil that has won numerous prizes. A.O.C. (appellation d’origine contrôlée) means that the oil was produced in the valley of Les Baux in Provence, France.

Hugues, 47, and his wife, Catherine, 44, built their olive oil mill at the foot of the medieval town of Les Baux in Provence just four years ago. They had recently returned from the United States where they had been living for some 15 years as Hugues ran a company and “realized the American dream.”

The couple decided to sell the company and “come back to our roots.” They felt it was a good time to take their two young children, then ages 6 and 8, back to France and to the world of grandparents, relatives and cousins. And, it was also a good time to realize another dream, financed with the profits of their U.S. venture.

The couple owned a grove of olive trees in St. Remy de Provence. Catherine had often returned to France from the States in the summers to work on them.

“I caught the olive virus,” acknowledges her husband. “If you have an olive tree, you will understand. It starts with just one olive tree.”

Their original plan was to buy an old mill and make their own oil.
