Rapid Analysis of Acrylamide in Foodstuffs without Chromatography Revealed at BMSS Meeting

Mass Spec Analytical demonstrates Acrylamide Quantification in Foodstuffs in Minutes Using a Thermal Extraction Ionisation Source without Chromatography

Ambient Ionisation Mass Spectrometry (AI-MS) is an exciting field of mass spectrometry where direct analysis of samples in real time without sample preparation or long run times is possible. However, without chromatographic separation to minimise matrix effects, there is concern that quantitation is not reproducible using AI-MS alone.

At the recent British Mass Spectrometry Society Ambient Ionisation Special Interest Group meeting at Huddersfield university, Mass Spec Analytical presented a Thermal Extraction Ionisation Source (TEIS) coupled to a SCIEX triple quadrupole instrument for the identification and quantitation of acrylamide within seconds using a direct injection. Acrylamide is an organic compound and a naturally occurring by-product in carbohydrate-rich foods that are prepared at low moisture levels and at temperatures above 120C. The European Food Safety Authority has confirmed acrylamide to be a probable carcinogen, so it is important to be able to quantify levels are below commission regulation limits (EU) 2017/2158.

Our rapid quantitation method for acrylamide in foods was demonstrated using the Mass Spec TEIS with a high degree of reproducibility suggesting quantitation is possible using AI-MS. The sample preparation is simple and amenable to automation, suggesting that the TEIS method can significantly increase sample throughput without a concomitant loss in quantitation accuracy.

A poster was presented that provides more detail. An application note will be published shortly. Contact MSA for more information.
