MALDI-ToF workshop (food microbiology) in Oslo, Norway, on 5 June 2019

The workshop, which is arranged by NMKL, is not only useful for MALDI-ToF users but also for those who are considering to use MALDI-ToF in the future. It will focus on microbiology, however, there will be presentations about the general principles of MALDI-ToF, what is required, how to use it, how to expand the database, experience with usage and also presentations by the suppliers of the equipment.

New NordVal International certificate

Certificate 048 for the biosensor developed by DirectSens® to determine residual lactose in lactose-free milk products has been extended. At the same time, the name of the method was changed from LactoSens® 0,01% to LactoSens®R. New validation studies have been performed to validate that the biosensor LactoSens®R may also be used to determine residual lactose in milk samples with a fat content of up to 36% and in fermented milk products: yoghurt, cream, sour cream and curd. Further, it was assessed that the sensor is also applicable to lactose-free flavoured yoghurts and milk drinks (coffee, cacao, fruits). In addition, it was verified that the sensors are stable for at least 3 days' storage at 30⁰C. See the certificate here.

 

Three new certificates for Analytik in Milch Produktions- and Vertriebs- GmbH, Germany, have been issued. The methods describe Brilliant Black Reduction tests in microtiter plates for detection of anti-microbial agents in bovine milk. The inhibitors lessen or inhibit metabolic activity of the test bacteria. Detection may be visual or photometric. The methods have been tested in a large test for a range of different anti-microbial agents. The results are compared with EU maximum residue limits and POD curves are given.

The new certificates are:

NordVal International Certificate 051 for “BRT Inhibitor Test - see the certificate here

NordVal International Certificate 052 for “BRT MRL Screening Test” - see the certificate here

NordVal International Certificate 053 for “BRT hi-sense” - see the certificate here

Sensory quality control method for drinking water has been updated

NMKL Method 183 describes the sensory quality control method for drinking water. The Finnish / English version of the method has been updated and now includes also test setup and parameters for the appearance of drinking water. Furthermore, the references have been updated. Update of the Norwegian / English version is expected to be ready early 2018.

New method for determination of sodium by capillary electrophoresis in foodstuffs

NMKL method No. 203 describes the determination of sodium content in foodstuffs by capillary electrophoresis (CE). The CE method is quick and needs both very little sample handling and low amount of solvents. It is applicable to various matrices such as bread, vegetables and meat products. The salt content is calculated from the sodium content with the formula: salt = 2.5 x sodium.

Sodium is extracted from sample and analysed by CE with diode array detector. The minimum content of sodium that can be detected and quantified is 0.03 g/100 g.

International symposium in Norway in June 2019: Speeding towards -omics ...

Chemical and Microbiological Food Analyses

Don’t miss the opportunity to participate in this international symposium in Oslo, Norway, on 3-4 June 2019 arranged by AOAC Europe – NMKL – NordVal International.

The purpose of the symposium is to bring together scientists, technicians and companies to discuss emerging technologies and techniques with emphasis on recent advances and applications in food analyses.

The scope of this symposium is to discuss different aspects of use, validation and application of –omics related to food, but not only.

The topics are presented in plenum and in parallel sessions:

  • Genomics, proteomics, transcriptomics, metabolomics, foodomics
  • New rapid methods
  • Multi-methods
  • Hand-held instrumentation
  • Digitalization of the analytical process (from sampling to interpretation of results)

For programme see here.

New method for determination of isotope dilution in foodstuffs

NMKL method No. 202, "Methylmercury: determination by isotope dilution GC-ICPMS in foodstuffs", describes the quantitative determination of mono-methylmercury (MMHg) (10-5000 µg/kg dry weight) in mainly marine biota samples. The principle of the method is that the sample is spiked with an appropriate amount of Hg isotope-enriched MMHg and extracted. After derivatisation the sample is analysed using GC-ICPMS. The GC separates the different mercury species before MMHg is atomised and ionised in the high temperature of the ICP. The ions are extracted from the plasma, and in a mass spectrometer the ions are separated by their mass/charge ratio.

2nd edition of procedure on control of microbiological media is now available in both Scandinavian and English language

NMKL procedure No. 10 describes the control programmes and methods which should be applied when preparing microbiological culture media in a quality-assured laboratory. The procedure includes both solid and liquid culture media in the following categories: purchased, ready-to-use culture media; culture media prepared from commercially available dehydrated media; culture media prepared from the individual components.
