Journal Highlight: Quantitative analysis of bioactive compounds from aromatic plants by means of dynamic headspace extraction and multiple headspace extraction-GC/MS

Date: May 16, 2016

Author: separationsNOW

Seven bioactive monoterpenes in 4 aromatic plants (sage, cardamom, lavender, and rosemary) were quantified in liquid extracts and directly in solid samples by dynamic headspace-GC/MS and multiple headspace extraction-GC/MS, respectively.

Noble gases: neon lights, anaesthetics... and doping agents?

Date: May 1, 2016

Author: Ryan De Vooght-Johnson

The noble gas xenon, as well as being a common anaesthetic, increases oxygen delivery in the body, leading to widespread misuse in sport. Researchers from Hong Kong now describe a method to detect the gas (and its cheaper sibling, krypton) in racing horses.

Journal Highlight: Analysis and occurrence of dichloropropanol fatty acid esters and related process-induced contaminants in edible oils and fats

Date: Apr 18, 2016

Author: separationsNOW

A headspace GC/MS method for the indirect determination of ester-bound dichloropropanols uses mild alkaline-catalysed release of chlorohydrins and glycidol, followed by a transformation of glycidol to monobromopropanediol.

Dangerous cholesterol by-products detected in processed meat, cheese and fish

Date: Apr 14, 2016

Author: Ryan De Vooght-Johnson

LDL cholesterol is known to be bad for heart health, but when cholesterol is oxidised it may become even more dangerous. This study describes a new and efficient method for detecting cholesterol oxides, applied to common processed foods.

Is sea air really good for you?

Date: Apr 7, 2016

Author: Ryan De Vooght-Johnson

The air around us contains millions of tiny particles, some of which contribute to global warming. A new study from Japan investigated these ‘aerosols’ in the air above the Pacific Ocean, finding a new set of chemicals that may help to predict effects on climate, air quality and human health.

A reason to wash your vegetables

Date: Mar 21, 2016

Author: Ryan De Vooght-Johnson

As well as damaging the environment, pesticides can be harmful to the consumer when residues are left on crops. A recent study analysed concentrations of over 50 pesticides in a range of commonly eaten vegetables, several of which exceeded safe levels.

Journal Highlight: High-throughput microanalysis of large lignocellulosic sample sets by pyrolysis-gas chromatography/mass spectrometry

Date: Mar 14, 2016

Author: separationsNOW

A high-throughput pyrolysis-GC/MS system for lignocellulose that incorporates automated multivariate-based data-processing was demonstrated on 300 Arabidopsis mutants and 5 biological replicate trees.

Defining the ‘fresh’ in fresh fish

Date: Mar 10, 2016

Author: Ryan De Vooght-Johnson

Fish is best eaten fresh, which can be difficult, given its very short shelf life. To identify the optimum window for eating cod, a team of French researchers used gas chromatography to detect molecular indicators of freshness.

Journal Highlight: Impact of comprehensive two-dimensional gas chromatography with mass spectrometry on food analysis

Date: Feb 15, 2016

Author: separationsNOW

The use of comprehensive two-dimensional gas chromatography with mass spectrometry in the untargeted (general qualitative profiling and fingerprinting) and targeted analysis of food volatiles has been reviewed.

The characteristic aroma of different Chinese liquors

Date: Feb 12, 2016

Author: Ryan De Vooght-Johnson

Chinese liquor is big business. Renowned for their characteristic flavours, some bottles can sell for over US $3000. However, what makes each liquor unique is not fully understood. A new study applied taste tasting alongside GC-MS to identify the tasting notes and volatile compounds associated with three major types of liquor.
