  11. C1b 5.4 What is added to our food? Food additive: a substance added to food to -keep it longer -improve taste or appearance Detecting Additives Chromatography Mass Spectrometer

  12. C1b 5.4 What is added to our food? Chromatography This technique separates different compounds based on their solubility in a solvent which effects how far they travel across a surface.

  13. C1b 5.4 What is added to our food? Chromatography This technique separates different compounds based on their solubility in a solvent which effects how far they travel across a surface. Eg paper

  14. C1b 5.4 What is added to our food? This technique identifies both: elements and compounds and measures the relative formula mass Mass Spectrometer

  15. C1b 5.4 What is added to our food? This technique identifies both: elements and compounds and measures the relative formula mass FT-ICR MS can resolve dozens of peaks at the same nominal mass, as shown in this expanded view of a negative-ion spectrum of an olive oil. . (Fourier-transform Ion Cyclotron Resonance) Mass Spectrometer

  16. C1b 5.4 What is added to our food? This technique identifies both: elements and compounds and measures the relative formula mass Mass Spectrometer

  17. C1b 5.4 What is added to our food? Complete analysis of vegetable oils has yielded markers, such as the relative abundance of C18 fatty acids with zero, one, two, or three double bonds , that can be used to check the purity of different oils. This technique identifies both: elements and compounds and measures the relative formula mass Mass Spectrometer
