Food and Beverage Analysis

The benefits of olive oil as part of a healthy diet reaches back to the 1950's. Methods were developed to determine benzene, toluene, ethylbenzene, xylenes and styrene (BTEXS) by static headspace methods.

By identifying maturation tracers and molecules commonly responsible for taste defects, gas chromatography–mass spectrometry (GC–MS) augments expert opinion with objective and quantitative information. When using a solid phase micro extraction (SPME) method, GC–MS requires very small sample sizes and a minimum of sample preparation while providing rapid analysis of target molecules. GC–MS can provide an automated technique with repeatable results for detecting all of these compounds.

LCGC asked a group of experts about the techniques and technologies they chose to use in food analysis, and how they made those choices.

A fast heart-cutting liquid chromatography–gas chromatography (LC–GC) method for the analysis of mineral oil saturated hydrocarbons (MOSHs) in a range of widely consumed foods is described.

The global food, beverage and agricultural industry caters to the population of the entire world. Even though the food industry does not rely on analytical instrumentation to the same extent as perhaps other industries, the sheer size of the industry results in a considerable market for such instruments.

The iDQuant? Standards Kit for pesticide analysis of certified reference material (ISP Guide 34, IOS/IEC 17025, and ISO 9001:2008) includes 204 pesticides in 10 mixes at a concentration of 100 ?g/mL. This kit has been designed to eliminate the need to source pesticides individually, and measure each one manually. This allows users to setup, verify, and validate the performance of pesticide screening methods faster.

With more than 800 pesticides currently in use there is growing concern by government agencies about the effect of pesticide exposure on human health. While analytical techniques like GC or GC–MS have traditionally been used for pesticide analysis, LC–MS-MS has become the technique of choice due to speed, increased sensitivity, and reduced sample preparation. The following describes an LC–MS-MS method for screening of 534 pesticides in food products.

A method has been proposed that positively identifies over 100 common pesticides using a GC column with MS detection.

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.
