Thermo Fisher Scientific?s Global Food Safety Response Centre in Dreieich, Germany has announced that it is monitoring the dioxin crisis in Germany where animal feed additives may have been tainted with industrial fats containing the toxic chemical.

Participants in this Tech Forum are Arthur Sims and Brent Lefebvre of AB SCIEX, Jennifer Singh of EMD Millipore, Gerry Broski of Thermo Fisher Scientific, and Paul B. Young of Waters Corp.

The United States Food and Drug Administration in Irvine, California, USA has purchased the Dionex ICS-5000 ion chromatography system with mass spectrometer for the analysis of biogenic amines in fish samples.

Whether organic produce provides any actual health benefits is still controversial, and a recent study of organic carrots, onions and potatoes has claimed that the process may add nothing at all.

This article describes a straightforward ion chromatographic method that uses isocratic elution and pulsed amperometric detection (PAD) to sensitively determine water-soluble polyols and sugar alcohols as well as mono-, di- and oligosaccharides in essential and non-essential foodstuffs. While carbohydrate determination of most foodstuffs requires only minimal sample preparation such as dilution and filtration, samples with interfering matrices such as protein-containing dairy products have to be dialysed before injection.

In food, organic acids originate from the natural biochemistry processes or are added as preservatives, acidulants and stabilizers.

Wyatt Technology?s instruments are to be used by the Biological Macromolecules Joint Research Unit of the Université de Provence and Université de la Méditerranée in Marseille, France, to eliminate bacteriophage infections in dairy production.

Gerry Broski, food safety marketing director for Thermo Fisher Scientific speaks about two new analytical screening methods that have recently been developed at the company's food safety response centre.

A study into the composition of krill oil may offer new insights into the complexity of this source of omega-3.

Beer is one of the world?s oldest and most widely consumed alcoholic beverages, and a recent study of its proteome may provide brewers with ways to make it even better.

A simple and rapid test for cobalt in leguminous plants has been developed that Spanish and Venezuelan chemists claim could provide an alternative to more expensive methods.

Following the accident at Chernobyl Nuclear Power Plant in 1986, the surrounding area remains substantially contaminated with radioactive isotopes. A study into the adaptations of the surrounding plant life has suggested that the plant proteomes remain largely unchanged by the radio contamination.

A robust, selective and sensitive separation method for the determination of four steviol glycosides in stevia plant matrix is demonstrated. In addition to the two calibrated substances two more glycosides could be found in stevia plant extracts by LC–MS. Using a popular Eurospher NH2 phase and applying moderate separation conditions results in an inexpensive and precise analysis method.
