m these plants is sometimes mixed with olive oil, but not disclosed on the label.
The test focuses on key regions of two genes, matK and psbA-trnH, which occur widely throughout nature, including in olive, canola and sunflower. The DNA sequence of specific regions of these two genes, Kahlon notes, provides a reliable basis of comparison, and can be used to detect the presence of the non-olive oils at concentrations of 5% or higher.
Though using PCR technology to detect specific plant DNA in ol
