Food and Beverage Analysis

The Food and Environment Research Agency (Fera) and Waters (Milford, Massachusetts, USA) have officially opened the first food safety training facility (York, UK), the first of its kind in Europe.

Malvidin, a polyphenol found in red wine, has been presented as a potential candidate for the reduction of heart disease.

The United States Pharmacopeial Convention (USP) has added nearly 800 new records, mostly from 2011 and 2012, to its Food Fraud Database, increasing the size of the database by 60%. The original database contained 1,300 records, covering fraud reports issued between 1980 and 2010. The database compiles data taken from publicly available reports in both scholarly journals and general media, with key findings published in the Journal of Food Science.

Sample preparation in this study involved QuEChERS extraction followed by a filter-based cleanup method that is easier and faster than dispersive solid-phase extraction.

This article describes how a food testing laboratory can transition routine high performance liquid chromatography (HPLC) methods to microflow LC for improved sensitivity, throughput, and robustness of analysis.

Levels of benzene, toluene, ethylbenzene, xylenes, and styrene (BTEXS) are a concern in olive oil. These compounds find their way into olive trees and hence into olives and olive oil mainly as a result of emissions from vehicles, bonfires, and paints into ambient air near orchards. This analysis uses a PerkinElmer? TurboMatrix? 110 Headspace (HS) sampler with a Clarus? SQ 8 gas chromatograph–mass spectrometer (GC–MS) to achieve detection limits below 5 ng/g and concentrations up to 100 ng/g.

A sensitive and selective liquid chromatography spectrometry mass spectrometry (LC–MS–MS) method to determine clenbuterol-like beta agonist residues in human hair was developed and validated.

Monday afternoon’s “Food and Environment†session will take place in Grand Ballroom F-K, starting at 4:30 p.m. The Session Chairs will be Andy Dang of San Jose University (San Jose, California), and Frantisek Svec of Lawrence Berkeley National Laboratory (Berkeley, California).

A novel "green chromatography" method for analysing melamine in milk is described. The method uses 100% water as the eluent and in the sample preparation stage and is reported to be a reliable and cost-effective method for laboratories in developing countries.

HPLC with diode-array and electrochemical-array detection overcomes sensitivity and specificity limitations in natural products analysis.

Antioxidants protect cells from the damaging effects of free radicals and offer numerous benefits for human health. Many phenolic compounds found in plants, as well as some vitamins, exhibit antioxidant activity. Several colorimetric assays exist to measure the total antioxidant capacity, typically expressed as Trolox or Gallic acid equivalents.

Red wine is a challenging matrix that contains organic acids, sugars, phenols, and pigments such as anthocyanins. This application note describes a simple, fast, novel, and effective method to clean up red wine co-extractives.

The monomer bisphenol A (BPA) is used to make polycarbonate plastic and epoxy resins and has been present in many plastic bottles and metal food and drinks cans since the 1960s.
