Understanding the business impact of chemical contamination on food products requires a rapid response.

RSSL is your expert partner for resolving contamination issues, from initial identification of the contaminants in foods to recognising its root cause (whether accidental or malicious), and taking appropriate corrective action.

We have 30 years’ experience in chemical contamination identification, including unknown peak identification, taint and off-flavour investigation and suspected contamination events.

Whatever the contaminant, our expertise in sampling, extraction and analytical methods, allows us to provide you with thorough and effective analysis.

We can identify:-

  • Heavy metals and elemental contamination
  • Cleaning agents including bleach and detergents
  • Drugs of abuse
  • Hydrocarbons, including oils, petrol and diesel
  • Substitution and adulteration of products such as alcohols and oils
  • Preservatives and colours
  • Cross contamination from packaging, production or storage
  • Acrylamide in a number of different food products including biscuits which we are UKAS accredited for

Our chemical contamination analytical services include:-

  • Chromatographic analysis
  • Spectroscopic analysis
  • Elemental determination
  • Energy dispersive x-ray analysis in the Scanning Electron Microscope
  • Semi-quantitative metals screen for ~70 elements

Acrylamide Management

Under new legislation which will come into force on April 2018 food businesses in Europe will be required to put in place practical steps to manage acrylamide within their food safety management systems.

RSSL offers a robust method to the food industry to quantify acrylamide. By carrying out  a survey routinely (many clients opt for an annual assessment), RSSL can help manufacturers understand which parts of their manufacturing process impact  acrylamide formation. RSSL's service has UKAS accreditation for biscuits, but the method is applicable to a number of different product matrices. The sample preparation is often complex, and the LC-MS technique used in detection/quantification is highly sophisticated and capable of detecting low levels of acrylamide.
