Application of stable isotope ratio analysis for olive oil and honey

Olive oil and honey are natural products whose quality is defined both by its botanical and geographical origin. Their consumption by humans began thousands of years ago. Consumers demand for certain varieties with premium prices. The versatile use of olive oil and honey have always been thought to be a part of a healthy lifestyle. At the same time, they are the most commonly adulterated ingredients, olive oil on the first and honey on the third place. Olive oil is adulterated with cheaper oils and honey with high fructose corn syrup (HFCS). These problems could easily be detected by liquid chromatography using an elemental analyzer isotope ratio mass spectrometer (LC EA IRMS). Isotopes of an element have different number of neutrons and different masses. Stable isotopes of an element are those isotopes that do not decay through radioactive processes over time. Some of these elements are hydrogen, carbon, nitrogen, oxygen, sulfur, strontium. A significant fraction of stabile isotopes always occurs in food. The carbon ratio tells us about feeding habits and the nitrogen ratio about available nitrogen in soil and atmosphere. A stable isotope ratio of hydrogen and oxygen provides information about climatic conditions of the region, sulfur about surface geology of the area. All these data can give us information about olive oil and honey adulteration and geographical origin.
