Aflatoxins, a mold largely produced by Aspergillus flavus and Aspergillus parasiticus1 are commonly tested mycotoxins found naturally in a wide range of agriculture crops and food products. Due to their harmful effects on human health, animal health, and global trade, aflatoxins are regulated in most countries and have established global limits in a wide variety of matrices.

The compound 4-methylimidazole (4-MEI) is formed as a byproduct in some foods and beverages. Caramel coloring Type III and Type IV in beverages is one of the ingredients which may contain 4-MEI. Products that potentially contain 4-MEI include certain colas, beers, soy sauces, breads, coffee, ammoniated livestock feed and other products.

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.

Mycotoxin testing awareness has increased as countries involved in world trade of raw agriculture and processed consumer products rely on a safe global food supply. Several mycotoxins are naturally produced and monitored; however, aflatoxins, produced mainly by the Aspergillus species, are considered to be the most important mycotoxin group in the world’s food supply to monitor.

Deoxynivalenol is a common mycotoxin found in wheat agriculture crops. Being the most popular agricultural cereal crop, wheat is also a dietary staple for about 35% of the global human population and animals. Safety of wheat food and agriculture products is a concern, with deoxynivalenol present in 90% of food and feed samples.

Deoxynivalenol is a common mycotoxin found in agricultural grain crops and final consumer processed products. Most impacted are wheat, barley, and corn. Deoxynivalenol, also known as Vomitoxin, is produced by Fusarium fungi and has a unique dual-stage growth cycle of producing mold during warm daylight and toxin during cool nights. There is no known procedure or processing that will remove deoxynivalenol that is already present in grain.

Mycotoxin testing in consumer food products has become increasingly important as global food trade increases, making it necessary to identify mycotoxins efficiently and accurately. Deoxynivalenol, also known as vomitoxin, is a mycotoxin commonly found in wheat feed crops. Because wheat is a highly-used raw agricultural export commodity in many counties for both animal feed and consumer food products, it is an important component in the diets of both humans and animals.

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.
