Learning about industry trends and discussing global challenges with others – that’s the AOCS Annual Meeting.
Since Sunday, Scientists from around the world have been in Denver (Colorado, USA) to present the latest research trends and technologies on fats, oils, proteins, surfactants and related materials.
Here's a little insight:
For almost a decade, mineral oil saturated and aromatic hydrocarbons (MOSH/MOAH) are considered as relevant contaminants in foodstuffs and are therefore analyzed by official authorities, food producers, and contract laboratories. The analysis is routinely performed by hyphenation of HPLC and GC-FID. Despite the use of this elaborated technique and harmonized methods, inter-laboratory comparisons still revealed insufficient precision of the obtained results. This especially holds true for the quantitation of MOAH in refined or tropical oils, such as palm oil, near the aspired limits of quantitation. Residual biogenic matrix compounds are the main reason for the observed discrepancies. Multiple analytical approaches were proposed in the past. The addition of mass spectrometry or comprehensive GCxGC methods were only two ideas. As part of the presented work, investigations were made how these interfering compounds can be removed more efficiently during sample preparation. As an outcome, an improved procedure could be derived as shown in the figure.
Kinetic studies revealed the underlying problems and gave indications about unintended side reactions and possible analyte losses. Overall, this presentation dealt with the question what obstacles and bottlenecks are still present in the analysis of MOSH/MOAH and how they can be overcome.
