Edible Oils

The edible oil industry boasts revenue measured in the tens of billions of dollars. As such, it can be subject to criminal acts of fraud aimed at increasing profits (adding a cheaper, inferior oil to boost the volume of a premium, higher priced oil). A GC fingerprinting technique can be used to monitor product for adulteration, and also to identify the source of oils in unknown samples. Following derivatization to convert the fatty acids to FAMEs, GC analysis is performed. This quick fingerprinting technique allows the oil type and purity to be identified, by comparison of the FAME ratios in sample oils to the FAME ratios in reference oil standards.
