    Everything You Wanted to Know about Olive Oil

    The debate about whether olive oil is healthy continues, but there is a lot of chemistry that goes on to produce a bottle.



    While “Olive Oil is Awesome,’ there are factors that impact the quality and shelf-life of a bottle of edible oil. Teledyne Leeman Labs tackled the challenge of determining trace elements in edible oils using ICP-OES in a recent study using its Prodigy 7 ICP configured for radial viewing.


    “Oils contain unsaturated fatty acids and relatively
high levels of phospholipids, which can react with
oxygen to produce unpleasant flavors and odors in
the oil. The presence of trace concentrations of
metals such as Ca, Cu, Fe, Mg and Ni promote
oxidation and can significantly reduce shelf life.
Vegetable oils are very high in phosphorus, calcium and magnesium as well as traces of iron. As the oil is refined, the levels of these metals are continuously reduced to improve the final product’s flavor, color and stability.”


    To ensure quality control throughout the refining process, accurate trace metal analysis is required.
