Chapter 2: Determination of the Origin of Tomato Products
Published:07 Jan 2019
The globalization of markets and the information now required about traded products have made it necessary to adopt regulations for free trade. In particular, statements of the certification and determination of origin are now required. These attract increasing attention and interest from both consumers and producers, not only for their economic added value but also for their implications involving human health. The present chapter reports and reviews some of the most relevant studies that have addressed the investigation of the geographical origin of various tomato products by using different analytical techniques coupled with multivariate statistical analysis. Specifically targeted analysis focuses on stable isotopes, micro and macro elements, or chemical markers, while the untargeted approach relies on NMR-based metabolomic analysis.
