From 2008 to date, basically, single‐cross microchip electrophoresis ( ME ) design has been used for food analysis with electrochemicaland laser‐induced fluorescencedetection being the most commonprinciples coupled. In the last 4 years, the main outlines were: (i) the exploration of new analytes such as heavy metals, nitrite, micotoxins, microorganisms, and allergens; (ii) the development of electrokinetic microfluidic (bio‐) sensors into microchip format for the detection of toxins; and interestingly (iii) although sample preparation is still performed off‐chip, an important increase in works dealing with complicated food samples has been clearly noticed. Although microchip technology based on electrokinetics is emerging from important fields such as authentication of foods, detection of frauds, toxics, and allergens; the marriage between micro‐ and nanotechnologies and total integration approaches has not reached the expected impact in the field but it is still a great promise for the development of ME of new generations for food analysis.
