Abstract: | An analytical method has been developed to evaluate the intensity of the bitter taste in virgin olive oil. Results from the
proposed method, based on extraction of the bitter constituents of virgin olive oil with methanol/water and measurement of
the absorbance at 225 nm, show a significant correlation with the intensity of bitterness that had been evaluated in a sensorial
manner by a panel. The developed method, therefore, offers a real alternative to the panel test for the evaluation of this
attribute. |
