Adulteration detection in olive oil using dielectric technique and data mining

Raman Spectroscopic Detection of Olive Oil Adulteration

Olive oil is among the most commonly adulterated food products. Raman spectroscopy has the potential to be utilized in measurements of olive oil to establish purity from adulteration with other, less expensive, oils. This application note reviews some of the most compelling data present in recent scientific literature to support this claim. Background and Motivation Extra‐virgin olive oil is in...

Olive Oil Adulteration

Among edible oils, olive oil shows important and outstanding characteristics due to its differentiated sensorial qualities (taste and flavor) and higher nutritional value. It is an important oil that is high in nutritional value due to its high content of antioxidants (including vitamin E) 1. Several health benefits, such as its ability to lower LDL cholesterol and its anti-inflammatory activit...

Detection of extra virgin olive oil adulteration with lampante olive oil and refined olive oil using nuclear magnetic resonance spectroscopy and multivariate statistical analysis.

High-field 31P NMR (202.2 MHz) spectroscopy was applied to the analysis of 59 samples from three grades of olive oils, 34 extra virgin olive oils from various regions of Greece, and from different olive varieties, namely, 13 samples of refined olive oils and 12 samples of lampante olive oils. Classification of the three grades of olive oils was achieved by two multivariate statistical methods a...

Detection of Virgin Olive Oil Adulteration Using Low Field Unilateral NMR

The detection of adulteration in edible oils is a concern in the food industry, especially for the higher priced virgin olive oils. This article presents a low field unilateral nuclear magnetic resonance (NMR) method for the detection of the adulteration of virgin olive oil that can be performed through sealed bottles providing a non-destructive screening technique. Adulterations of an extra vi...
