Citrus fruits and juices contain organic compounds and inorganic minerals. There are major, minor and trace mineral elements found in orange and other citrus juices. The concentrations of some specific elements may be utilized to determine and distinguish the geographical country of origin and the blend percentage of citrus juices.
ICP-MS (Inductively Coupled-Plasma Mass Spectrometry)
The levels of trace elemental markers are measured in orange juices and blends for origin determination and blend percentage. ICP-MS (Inductively Coupled-Plasma Mass Spectrometer) may be used for both qualitative and quantitative analysis.
Identification of Country of Origin (COO)
Databases comprised of the concentrations of trace elemental markers from various juice sources are used to identify the country of origin (COO) of orange juices. Artificial ‘neural networks’ are ‘trained’ from this data and statistical evaluations are used to assist in COO determinations. We have primarily built COO databases emphasizing juices from two countries, Florida and Brazil. Our goal is to expand our databases with data derived from juices produced in other juice producing regions around the world.
