The complexity of many food samples places a great demand in terms of both separation capabilities and specificity of detection. In this article, a novel system for fully automated comprehensive two-dimensional liquid chromatography (LC?LC) is discussed.

Food for human consumption and animal feedstuffs contain a variety of mono-, di-, oligo-, and polysaccharides with different functions. In this article specific liquid chromatographic (LC) systems (column, mobile phase, and detector), which are used to determine different carbohydrates in food and feed matrices, are described.

Food provides the body with energy and good food is indispensable for a healthy life.

This article is focused on the detailed qualitative analysis of the fatty acids and the unsaponifiable constituents of a vegetable oil derived from a food-industry waste product, namely lemon seeds.

If food flavor is not as expected, it can damage consumer confidence and give the perception of poor quality. Setting analytical standards of what constitutes an acceptable flavor can be challenging, and while methods based on total volatiles or specific marker compounds can be a useful quality control check, a more investigative approach is often required.

Advances in nano-ultrahigh-performance liquid chromatography (nUHPLC) and "plug-and-play" micro-UHPLC (?UHPLC) for the detection of veterinary drugs and steroids in porcine meat and urine respectively are described.

Edible oils and fats are complex mixtures of compounds. To understand the properties of an oil or fat, information on groups of molecules, as well as individual molecules, is needed.
