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).
