The European Commission's Joint Research Centre has developed three new methods to detect an illegal clouding agent that can be found in sports drinks imported from Taiwan.
In late May, the Taiwanese authorities informed the European Commission that significant amounts of phthalates were illegally added to certain categories of sports drinks. Normally, producers of sports drinks, jelly and fruit pulps use a palm-oil based product to obtain a cloudy appearance, but in this incident, it was largely replaced by two cheaper substances: bis-(2-ethylhexyl) phthalate (DEHP), and di-iso-nonyl phthalate (DINP). DEHP and DINP are commonly used as plasticizers in many plastic products. These chemicals are believed to affect reproductive performance and fertility, and have been linked to developmental problems with children, so that they are prohibited in the production of food, and their use in plastic toys and childcare products is restricted in the EU.
Under a request from the commission's Directorate-General for Health and Consumers, the JRC developed and validated three new testing methods that allow the substances to be rapidly and accurately detected.
The methods are available from the JRC website at http://irmm.jrc.ec.europa.eu/activities/phthalates
Examining Alkaloid Profiles in Milk with LC-MS
February 10th 2025Research conducted by The Technology Transfer Center of the Edmund Mach Foundation (San Michele all'Adige, Italy) and the University of Udine (Udine, Italy) used liquid chromatography coupled with high-resolution mass spectrometry (LC-MS) to investigate alkaloid transfer from alpine pastures to milk.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
