This study assesses whether two commonly used plastic packaging materials are safe for use. Their potential migrants are analyzed using data-independent acquisition and liquid chromatography coupled with high-resolution, accurate-mass mass spectrometry.

Using highly specific immunoaffinity solid-phase extraction to selectively extract and enrich aflatoxins prior to HPLC-FLD analysis, without derivatization, low LOQ values-far below the European regulations-can be achieved even in highly complex and fatty matrices.

The method described here is a simple method for detection of a wide spectrum of metals and for quantitative analysis over a wide dynamic range of elements, including both toxic metals and those metals essential for health and well-being.

Application of multivariate statistical analysis to a combined data set demonstrated that SIFT-MS discriminates premium quality beef from eight sensory defects, and, therefore, could be applied as an instrumental grading tool, obviating sensory panel grading.

A discussion of challenges in mycotoxin analysis, a new multi-analyte method that does not require sample cleanup, and how analytical chemistry can help reduce contamination by these toxins along the food chain.

A new method enables quantification of pyrrolizidine alkaloids in a range of food matrices.
