“…Among analyzed biogenic amines, putrescine and cadaverine were found to be good indicators of freshness because their levels rapidly increased during the process of meat aging. Better LODs (10–42 μg/L) were obtained in the analysis of seven unlabeled biogenic amines (spermine, spermidine, histamine, cadaverine, β‐phenylethylamine, tyramine, and tryptamine) by using CZE with amperometric detection (AD) . Several additives were tested to improve biogenic amine separation.…”

In this work, the analysis of foods and food components using capillary electromigration methods is reviewed. The present work presents and discusses the main CE applications performed in Food Science and Technology including the new field of Foodomics, reviewing recent results on food quality and safety, nutritional value, storage, bioactivity, as well as applications of CE for monitoring food interactions and food processing. The CE analysis of a large variety of food-related molecules with different chemical properties, including amino acids, peptides, proteins, phenolic compounds, carbohydrates, DNA fragments, vitamins, toxins, pesticides, additives, and other minor compounds is described. The use of microchips, CE-MS, and chiral-CE in food analysis is also discussed as well as other current and foreseen trends in this area of research. Following the previous review by Castro-Puyana et al. (Electrophoresis, 2012, 33, 147–167), the current review covers the papers that were published from February 2011 to February 2013.

“…A series of standard mixture solutions of the six amines were tested under the optimal conditions to determine the linearity of this method. As listed in Table , the LODs of this method (S/N = 3) were 6.15–68.32 nM, which were approximately 100‐fold lower than those reported in several previous studies . Compared with the common CE‐AD method (Figs.…”

It is difficult to detect biogenic amines (BAs) in biological fluids because of their very low concentrations. In this paper, we reported an on-line sample preconcentration method in CE-amperometric detection (CE-AD) based on a dynamic pH junction, and a concentration enhancement of approximately 100-fold was achieved compared with the classical CE-AD methods in the simultaneous analysis of six BAs in urine (dopamine, epinephrine, norepinephrine, tyramine, tryptamine, and serotonin). The technique is proposed based on the sharp pH change generated at the boundary between an acidic sample and the basic BGE zone. Under optimized conditions, all analytes were successfully focused and well separated within 20 min with high efficiency and sensitivity (LODs at S/N = 3 ranging from 5.34 to 68.3 nM). For the analysis of urine samples by this method, satisfactory recoveries were obtained without a complicated pretreatment step or derivatization process. Therefore, it is self-evident that this approach for the analysis of real biological samples has great potential in the future.

“…Although these methods are convenient and simple, sample pretreatment is usually required to reduce interferences. Thus far, only a few detection methods have been reported for the determination of several biogenic amines in food based on conventional CE coupled with amperometric detection (AD) ; W. L. Li et al 2012), pulsed amperometric detection (Sun, Yang, and Wang 2003), conductometric detection (Kvasnick and Voldrich 2006), contactless conductivity detection (Gong and Hauser 2006), and chemiluminescence detection (J. F. Liu, Yang, and Wang 2003;Y. M. Liu and Cheng 2003;M.…”

A novel method based on miniature capillary electrophoresis with amperometric detection was developed for the rapid determination of 1,2-diaminoethane and 1,6-diaminohexane, which are restricted compounds present in plastic. The use of online preconcentration significantly improved the limits of detection compared with conventional methods. Under the optimum conditions, the analytes were separated from other aliphatic diamines within 6 min with low limits of detection (1,2-diaminoethane: 0.01 ng/mL, and 1,6-diaminohexane: 0.1 ng/mL). The method was successfully applied to determine the analytes in bottled drinking water. The method does not require off-line preconcentration and derivatization steps, providing an alternative method for the rapid determination of diamines in drinking water.
