Testing Samples for Food Safety

When it comes to food samples, it is important to know how efficient your workflow is. It is also vital to have confidence that the knowledge that is being displayed is everything your sample has to offer.

In a series of free webinars, LECO outlines what can be achieved when it comes to food safety analyses.

Automated Thermogravimetric Determination of Moisture and Ash in Flour

The AOAC Official Method (925.10) Solids (Total) and Moisture in Flour uses a manual, air oven, loss-on-drying technique that is employed widely across the food industry.

AOAC Official Method (923.03) Ash in Flour also uses a manual, air oven, loss-on-drying technique.

Within this webinar, Jeffery Gast discusses how an automated thermogravimetric moisture determination instrument such as the TGA801 can comply with AOAC Official Method requirements for oven temperature and airflow while simultaneously reducing operator and analysis times, boosting the overall efficiency of the entire workflow.

Food Safety: A Journey Beyond the MOSH&MOAH Hump in Food Determination

LC-GC-FID is the current analytical method for the determination of Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH). Yet, the chromatographic profile acquired using the approach is more often than not just a bunch of unresolved substances.

However, GCxGC-TOFMS/FID is a promising solution for the quantitive characterization of MOSH and MOAH and helps identify markers that can help determine the source of contamination, allowing users to take appropriate action.

Here, Giorgia Purcaro introduces the challenges faced when conducting MOSH/MOAH analysis. She also discusses how introducing a GCxGC-TOFMS analysis into your process can boost results.

Application of Two-Dimensional Gas Chromatography with Mass Spectrometric Detection for Analysis of Pesticide Residues in Foodstuffs

Since 2005, the Czech Agriculture and Food Inspection Authority has implemented the use of GCxGC-TOFMS for the analysis of pesticide residue in food of plant origin. 

Radim Stepan talks about progress and achievements made to the instruments and the analyses used for pesticide residue analysis in cooperation with the University of Chemistry and Technology Prague.
