Food and Beverage Analysis

Waters has launched a programme to support scientific innovation in the fields of health and life science research, food safety and environmental protection.

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 nonessential foodstuffs.

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.

AB Sciex Application Note

Metrohm Application Note

PerkinElmer Application Note

Agilent Technologies Application Note

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.

PerkinElmer Application Note

Using narrow-bore column fast GC combined with rapid scanning qMS to analyse flavours and fragrances is described.

Practical HPLC, HILIC and RP-LC methods of analysing common food and beverages containing polyphenols are presented.

Phenomenex Application Note

We spoke to Waters about the development of an international food safety training laboratory set to open next year and how this will help specialists meet global standards.

Furan is naturally occurring at low levels in many foods and drinks (1).

An overview of current chromatography-based food toxicant screening is presented.

Agilent Poroshell 120, a superficially porous particle column, offers resolution and speed similar to columns packed with 1.8-µm totally porous particles, without generating high back pressure.

AB SCIEX Application Note

This paper describes the use of the AB SCIEX TripleTOFTM 5600 LC–MS-MS system for targeted and nontargeted screening for pesticide residue in food samples.

Participants in this Technology Forum are Deanna Hurum of Dionex Corporation, Sue Steinike of Shimadzu Scientific Instruments, and Gerry Broski and Eric Phillips of Thermo Fisher Scientific.
