Claim One:
1. A method for detecting a geographical origin of a fresh commodity comprising the steps of: generating a plurality of neural network models, each having as a training set a data set from a plurality of samples of a commodity of known origins analyzed for a plurality of elemental concentrations using an analytical method selected from a group consisting of inductively coupled plasma-optical emission spectrometry and inductively coupled plasma-mass spectrometry; presenting to each neural network model for classification a test data set from a plurality of samples of a commodity of unknown origins analyzed for the plurality of elemental concentrations; employing a bootstrap aggregating strategy to combine the results of the classifications for each sample in the test data set made by each neural network model; and determining from the bootstrap aggregating strategy a final classification of each sample in the test data set indicative of a geographical origin of the commodity.
