An Analysis of Amino Acids in Oxidized and Unoxidized Feed Samples

Chinese researchers created a new approach for identifying and quantifying illegal additives in fruit and vegetable plums, types of often-consumed health-care foods.

Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.

A multidimensional liquid chromatography (LC)-based technique was created to help profile antioxidant metabolites in onion leaf extracts.

U.S. Department of Agriculture researchers used QuEChERSER-based methods to analyze chemical contaminants in foodstuffs in a new study published in the Journal of Chromatography A.
