  • Microalgae extracts on virgin olive oil may have important health benefits

    Carotenoids, anti-oxidant molecules found in marine microorganisms, prevent the deterioration of fatty acids in olive oil, which prevent from going rancid and increase its life. This was demonstrated by a group of researchers from the Department of Physical and Analytical Chemistry of the University of Jaén (UJA).

    According to scientists, in laboratory, these bioactive elements increase protection against rancidity of oil or deterioration of the natural fatty acids when in contact with air.

    Stopping this process, it is possible to extend the date of juice consumption, although at present is usually twelve months, with the extra intake of antioxidants it could exceed the year.

    This increase in resistance to oxidation also results in a major stability of the oil in its exposure to light -avoiding degrade- and to temperature changes, for example, when used in deep fryer.

    In this case, antioxidant molecules allow, despite the heating cycles, the oil to retain its properties.

    Incorporating these microalgae extracts on virgin olive oil may have important health benefits, since, according to what experts say, the deficit of carotenoids means less protection against those diseases whose onset is associated with lack of antioxidants, such as skin cancer.

  • France bans Italian olive oil to wipe out the bacteria

    Puglian farmers have refused, saying the uprooting of trees — some of them hundreds of years old — won’t halt the bacteria’s spread since trees can be infected without showing symptoms. They say the EU should instead be investing in research to wipe out the bacteria.

    “If we cut down 1 million trees this year, we’ll find another million infected a year later,” said Giovanni Melcarne, a Puglian olive producer and activist with the Voice of Olive commission opposing the cull. “We’ll never be able to resolve it.”

    Experts from the 28 EU nations meet again April 21 to discuss a unified EU position. A decision on action needs a “qualified majority,” which Italy couldn’t veto.

    In a statement announcing the boycott, Le Foll cited the risk of contamination on French vegetables if the bacteria were to be introduced on French territory.

    “There is no way to directly combat the bacteria,” he warned. “Once contaminated, only the complete uprooting of the vegetables can eradicate the infection.”
