More than 65% of the extra virgin olive oil on shelves around the US is defective due to poor handling or deliberate adulteration with extraneous, non-beneficial oils. The most prevalent and identifying defect in olive oil is rancidity, indicating the absence of expected health benefits such as antioxidants and polyunsaturated fats. This summer, we engineered a biosensor capable of quickly and cheaply evaluating rancidity defects in the chemical profile of olive oil, providing both consumers and retailers with a means of ensuring product quality. | More than 65% of the extra virgin olive oil on shelves around the US is defective due to poor handling or deliberate adulteration with extraneous, non-beneficial oils.

OliView: An Enzyme Based Electrochemical Biosensor Developed for Olive Oil Quality Control
More than 65% of the extra virgin olive oil on shelves around the US is defective due to poor handling or deliberate adulteration with extraneous, non-beneficial oils. The most prevalent and identifying defect in olive oil is rancidity, indicating the absence of expected health benefits such as antioxidants and polyunsaturated fats. This summer, we engineered a biosensor capable of quickly and cheaply evaluating rancidity defects in the chemical profile of olive oil, providing both consumers and retailers with a means of ensuring product quality.
Protein EngineeringLearn about how we engineered substrate specificity of Aldehyde Dehydrogenases and how we characterized specificity profiles. |
ElectrochemistryTake a look at how we developed a robust, coupleable electrochemical system to enable detection of various aldehydes in solution. |
Signal ProcessingTake a look at the potentiostat and corresponding software we developed to acquire and process our data. |
ResultsHere's the criteria that we met for this year's team. |
