The Column spoke to Professor Andrea Tapparo, of the University of Padova, Italy, about the use of chromatography to investigate declining honeybee populations.

This article examines the FFF technique with particular reference to the analyses of nanoparticles in food packaging.

Three scientists from the University of Illinois (Illinois, USA) have detected key compounds in honey using high performance liquid chromatography (HPLC) that can up-regulate detoxification genes. HPLC was performed on ethyl acetate honey samples identifying four compounds that induce detoxification genes, potentially required for the detoxification of pesticides.

6th International Symposium on Recent Advances in Food Analysis (RAFA 2013)

The six Tuesday afternoon presentations will examine food safety issues and advances in MS for characterization of additives and contaminants, including a quantitative comparison of DART-MS to GC?LC-MS methods for contaminant screening of foods, cosmetics, and packaging; experimental design guidelines for non-targeted analyses; a demonstration of the use of multivariate software in developing sample class prediction models based on a recursive workflow; the development of a mobile ambient mass spectrometry for on-site screening for plasticizers; melamine, and residue pesticides in tainted foods; an ultra-fast method and direct method to quantitatively monitor phenolic off-flavor compounds in wine to prevent product spoilage during aging; and a demonstration that UHPLC?QTOF-MS has the potential to differentiate whiskies on the basis of origin as well as age.

Contamination of food products with pesticides is a growing concern because of recognized damaging health effects. This concern is particularly acute for baby foods because of the vulnerability of young children to harmful effects of synthetic chemicals, particularly pesticides. This application note presents results for analysis of trace levels of 24 organophosphorus (OP) pesticides in baby foods using the Shimadzu GCMS-TQ8030 triple quadrupole GC–MS-MS.

Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable.

Caramel colorings are used as additives in a broad range of food and beverage products, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen (1).

Scientists in Portugal have been investigating important molecular and biochemical changes that occur when grapes are growing to find out how they affect wine aroma.
