With a working model, it was time for the ultimate test: Olive Oil

Nine samples of Extra Virgin Olive Oil were obtained and prepared for assay where three of the samples were known to be rancid. The velocities were recorded with each enzyme for a total of 27 data points. We used the best catalytic matrix from our previous model and again inverted the matrix and multiplied by the observed velocity. The results are below:

We noticed two outliers based on the unsaturated aldehyde prediction.

By plotting the predicted concentrations in three dimensions, we saw two obvious outliers. We deemed these two samples rancid based on their demarcation from the rest of the group, but also the high levels of both unsaturated aldehydes, and medium saturated aldehydes.
