Argan Oil Geographic Origin Analysis with SIFT-MS

4 months ago

Argan oil is an increasingly popular oil used for culinary and cosmetic purposes. In fact, I use it myself to keep my hair strong and healthy as it grows. The oil is harvested from the Argan tree and authentic Argan oil is only produced in certain Moroccan regions. Therefore, geographic origin analysis is an important tool throughout the supply chain to ensure that the material is unadulterated.

In a recently published paper, scientists investigated different methods for geographic origin analysis of Argan oil. They compared SIFT-MS with traditional chemical profiling, in terms of accuracy in determining the oil origin, ease of use and analysis speed. The study analyzed 95 different Argan oils originating from 5 different Moroccan regions.

While both techniques were able to reliably determine the origin of samples, SIFT-MS was found to be the quicker, easier and cheaper method.

Chemical profiling measures numerous parameters such as acidity, fatty acid content and peroxide value. Using multivariate analysis, these parameters are combined to achieve excellent classification according to region. However, the authors note how time consuming and expensive it is to obtain all parameters needed.

This is an excellent example of the power of SIFT-MS coupled with multivariate analysis for determining origin and quality of products.

SIFT-MS provides an alternative. By measuring the headspace of Argan oil samples, the authors developed a fast, reliable and non-destructive way to accurately measure the VOC profile. By applying multivariate analysis to this data, the origin of the oil can be readily determined.

This is an excellent example of the power of SIFT-MS coupled with multivariate analysis for determining origin and quality of products.
