Shimadzu Application Note

Responding to widespread recalls of potentially harmful phthalate?tainted food and beverages in Asia, AB Sciex has provided food safety investigators with a new method to identify the harmful plasticizer.

A combination of static and dynamic headspace analysis is described for routine profiling of both abundant and trace compounds in alcoholic beverages containing dry extract.

The Food and Environment Research Agency (Fera), an executive agency of the UK Government?s Department for Environment, Food and Rural Affairs (Defra), has selected Thermo Scientific GC?MS and LC?MS systems for its analysis of food products.

Green tea is drunk by many for the health benefits of the antioxidant catechins, which are thought to help fight heart disease and other conditions. The stability of these compounds is important for choosing the best storage conditions and determining an accurate shelf life. However, a study has revealed that they may not be as stable as was once thought.

Fraud in the fisheries sector can range from low-cost catfish sold as expensive sole to cod caught in the North Sea but declared as originating from the Baltic.

A process has been developed that uses combinational peptide ligand libraries to determine whether Cola drinks have been flavoured using natural vegetable extracts or only with artificial chemical flavourings.

This article describes modifications to US EPA Method 218.6 for detecting dissolved hexavalent chromium in drinking water, to permit a MDL of 0.001 µg/L

This article describes the current requirements for the analysis of POPs and the measures taken to improve workflows, enabling high throughput and low complexity screening using GC-MS-MS.

In this review, practical principles and guidelines for designing LC?LC methods are given.

The Food Safety Modernization Act, which was recently signed into law, is the country's first major food legislation since 1938, and increases the FDA's authority over the U.S. food supply. These new regulations require that foods, including baby food, be tested for pesticide residues.

Biogenic amines are present in protein-rich foods such as fish, meat, and milk. Their concentration increases during food decomposition.

Hydroxymethylfurfural (HMF), an organic compound containing aldehyde and alcohol functional groups, is naturally found in very low amounts in sugar-containing foods.

This note describes the use of the AB Sciex TripleTOF? 5600 LC–MS-MS system and data processing using the XIC Manager software to screen extracts of fruit and vegetable samples for pesticide residues.

The N-methylcarbamates and the N-methylcarbamoximes are among the most widely used pesticides in agriculture. Dionex has announced an improved HPLC method for the determination of these chemicals.

Unlike wine and whisky, beer tastes best when consumed fresh. After 6-12 months in storage, beer develops an unpleasant, bitter aftertaste. A study to identify the key substances that cause this bitter taste has been published in the Journal of Agricultural and Food Chemistry.

In this review, practical principles and guidelines for designing LCxLC methods are given.

The different aspects of food metabolomics are described using tomato taste as an example.

Flavour analysis of a Bloody Mary has provided some key insights into the best ways to mix the drink. The challenges and findings of cocktail?s analysis were presented at the 241st National Meeting & Exposition of the American Chemical Society.

Actinomycetes in soil produce various antifungal compounds that may protect crops from anthracnose disease.

Little is known about the role of selective attention in odour discrimination, which is why a group from Japan has assessed whether mice can discriminate between different liquors, just like a wine expert.

A high performance liquid chromatography (HPLC)–UV method was developed for the analysis of phenylurea herbicides and applied successfully to the analysis of herbicides spiked in three soft drink brands and tap water.

Scientists from chocolate company Hershey, in collaboration with other laboratories, have reported improved methods for determining the amounts of flavanol antioxidants in cocoa and chocolate. Flavanol antioxidants promote a healthy cardiovascular system by deactivating free radicals and helping to reduce blood pressure.

In the wake of the recent dioxin poisoning scare in Europe that sparked import bans on some German farm products, GC-MS is emerging as the perfect analytical tool for forensic analysis.

This article describes important aspects of food metabolomics using tomato paste as an example of this approach in practice.
