51 Food Analysis Application Data at RAFA 2011 Vendor Seminar
Experts from Bruker’s CAM division recently presented new data on several of its food testing solutions at the 5th International Symposium on Recent Advances in Food Analysis (RAFA), 2-4 November 2011 in Prague. Application case studies were presented as part of Bruker’s Vendor Seminar at the meeting, Speakers also highlighted the company’s commitment to transparent migration to Bruker solutions, and discussed how the Bruker team can assist with implementation and refinement of client methodologies.
Bruker's food testing solutions portfolio was recently extended with the addition of capability in the GC-MS arena, with the launch of the SCIONTM SQ and TQ GC-MS. There is significant risk to human health and the environment from increased pesticide use, and the analysis of pesticide residues in grain often results in enhanced responses and matrix interference leading to false positives and false negatives. The details of this case study, utilising the power and sensitivity of the SCION TQ GC-MS, were one of the highlights of Bruker’s Vendor Seminar.
"We enjoyed presenting the data on pesticide residues and matrix combinations where interferences and minimisation of false results with significant limitations in levels of detection and quantification in grains and pulses were discussed and illustrated," said Meredith Conoley, GC-MS Markets Manager for Bruker’s Chemical & Applied Markets (CAM) division. "These data, along with other presentations from our food testing solutions portfolio, serve to demonstrate Bruker's commitment to food analysis, food quality control and pesticide screening, along with meeting the expanding needs of a global market."
Studies evaluating Bruker's instrumentation focusing on recent advanced analytical technologies and emerging food-related applications were presented at RAFA including: a new complete solution for automated, comprehensive ESI-(Q-)TOF full scan accurate mass screening of pesticides in food with high confidence; matrix matched standards reveal matrix MRM interferences and minimise false results in pesticide residue analysis of grains and pulses; use and qualification of TXRF for trace element analysis of dietary supplements and nutrients; and NMR-based food quality screening.

Laboratory Blender Used in
E.coli 0157 Food Safety Study
Seward, the manufacturer and developer of the world leading, patented Stomacher® Paddle Blender range, highlights the recent use of the Stomacher®
400 Circulator, as part
of a reference method, for the assessment of
E.coli 0157 rapid testing protocols. In an extensive food safety study recently published in the E.U. by the Hygiene Unit of the Department of Public Health and Infectious Disease, Sapienza University of Rome, enzyme linked fluorescent assays (ELFA) and PCR were compared with the standard culture technique applying ISO 16654:2001 for E. coli 0157 detection in raw and cooked meat samples. The Stomacher 400 Circulator was used to prepare and homogenise samples in TSB with novobiocin for all testing protocols.
The study revealed that the new rapid methods are equivalent to the original direct culture technique. The team at the Rome- based facility concluded that the speed of testing of the rapid methods over the culturing techniques will be of great benefit to the public. Several days can be saved between sampling and detection, allowing a quick response to outbreaks.
The Stomacher 400 Circulator has a proven track record of excellent organism recovery from meat samples, with reduced sample debris ensuring minimal interference with subsequent sample processes. The quality of the sample is key to the performance of all rapid methods. It is for this reason that the Stomacher 400 Circulator is the most referenced laboratory blender in comparative studies between rapid microbiological detection methods and traditional reference techniques.
