Globalisation has been a significant factor behind the financial meltdown in which we all find ourselves now, but it has also led to significant changes in the variety and origin of the foodstuffs which line our supermarket shelves. In previous articles, I have discussed some analytical responses to the concerns which consumers have regarding claims made on the labels of processed foods; fingerprint technologies, such as near infrared spectroscopy, possess specific features which make them well-suited for deployment to address at least some of these concerns. The focus of this article is on the appropriate chemometric strategy to deploy in the confirmation or determination of issues of the provenance of a food or food ingredient.
