The compound 4 Methylimidazole (4-MeI) is made during the production of caramel color commonly found in foods and beverages, especially sodas.
The Codex Alimentarius of the World Health Organization sets a limit of 250 mg/kg of 4-MeI. Also, the state of California has added 4-MeI to its Prop 65 list at an exposure level of 29 μg/day.
This study looks at 4-MeI levels in sodas and malt sodas which
are sold in and outside the state of California. The first section, included in this poster, describes the performance of automated solid
phase extraction of 4-MeI using conventional HPLC/MS detection.

This poster demonstrates a novel, sensitive, cost effective and rugged method for the analysis of acrylamide in coffee and potato chips (crisps) using supported liquid extraction prior to LC-MS/MS
analysis. It demonstrates extraction from coffee down
to a concentration of 1 ng/mL and in potato chips to a level
of 10 ng/g (ppb).

This application note describes a Supported Liquid Extraction (SLE) protocol for the extraction of acrylamide from coffee using ISOLUTE® SLE+ columns with LC-MS/MS detection.
The method described in this application note achieves high recoveries of acrylamide in coffee. The method is sensitive enough to measure levels as low as 1 ng/mL in coffee (solution), 25 ppb in ground coffee (solid) or 125 ppb in instant coffee (solid, traditional or decaffeinated) and gives good selectivity from what is a challenging matrix.

This method describes the clean-up of acrylamide from cooked foodstuffs, using a multimode retention mechanism (hydrophobic, cation and anion exchange) for retention of interfering food components. The analytical technique is LC-MS-MS.

Melamine is traditionally used in making plastics, however, it’s low cost and high nitrogen content has led to exploitation in various sections of the food industry, most notably involving dairy products. Sustained melamine exposure can result in kidney stones and renal failure, with the young being most susceptible. This application note has been optimized on the RapidTrace+; an updated version of the current RapidTrace software which allows the system to process smaller bed heights than were previously possible. The application note shows recoveries of 88-90% with RSDs <10%.
