Food safety standards change and evolve
Ensuring the safety of the world’s food supply is critical, but there are concerns about the safety of global food supply chains because food can:
- Be grown and processed in widely differing environments under a variety of regulatory frameworks
- Travel thousands of miles and handled by many different operators and people
- Experience various storage conditions with temperature fluctuations that may affect shelf life
At any point in the process, products may become contaminated and unfit for consumption. Whether you are ensuring regulatory compliance or enhancing nutrition, our food safety testing solutions strengthen the entire food chain so you can deliver the uncompromised food products that consumers worldwide expect and deserve.
Ethylene oxide (EtO) - the new threat in food
Hundreds of products are currently being pulled of the shelves in supermarkets all over Europe, due to contamination with the pesticide ethylene oxide (E410, E412) found in sesame seeds and guar gum produced outside of Europe. Food labs are challenged by the amount of additional samples that need to be tested now for this contaminant.

Acrylamide - in the news again
The number of positive samples for acrylamide has dramatically increased in 2021. Acrylamide (2-propenamide) has been found in some cooked foods, including fried and baked starchy foods such as potato crisps, chips, roasted coffee, breads and peanuts. In baked and fried foods, acrylamide is formed from asparagine as a by-product of the Maillard reaction at temperatures above 120 °C.
Find complete workflow solutions for acrylamide in food samples, including a proven method used by food labs all over Europe, utilizing the Thermo Scientific TRACE 1310 gas chromatograph and ISQ 7000 single quadrupole GC-MS systems in one of our recent eBooks, GC-MS for food safety analysis.
Food analysis sample preparation is a key step in the analytical workflow. Sample preparation encompasses far more than liquid-liquid extraction (LLE), QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) and solid phase extraction (SPE) techniques.
There are several stages involved in order to get from an original food sample to the analytical sample.
- Sample collection, including transportation and storage should be controlled as to avoid cross contamination and potential degradation of analytes.
- Sample processing. This can involve a number of procedures such as cryogenically freezing, avoid analyte degradation, cutting, grinding, milling and mixing, to increase the total surface area of the sample and ensure that the analytical test portion represents the whole analytical portion.
Once the food sample has been prepared the analytes have to be extracted from the matrix into a solvent.
Automated sample preparation solutions include accelerated solvent extraction, for solid and semisolid samples using solvents at elevated temperatures and pressures, automated cartridge-based micro solid-phase extraction (µSPE) and evaporation systems. These systems help to avoid cross contamination and ensure fast turnaround times and consistent reliable results and are ideal for larger volume samples and large numbers of samples.
The most common manual technique, particularly in the case of pesticides residue analysis other contaminants in food samples, is QuEChERS. Clean-up, with the QuEChERS technique uses dispersive solid phase extraction, (dSPE) to remove undesired matrix components from the sample.
SPE is the most common form of cartridge clean-up. When using QuEChERS or SPE clean samples can be directly injected into the analytical system.
