Unfortunately, inappropriate refrigeration can sometimes lead to food spoilage, which is often difficult to detect. Such is the case for mackerel fish, which readily develop harmful levels of a substance called histamine when left at room temperature for too long. Histamine is neurotoxic and can trigger severe allergic reactions, including rashes, vomiting, and diarrhea. Because spoiled fish can sometimes look and smell completely normal, it is important to accurately quantify histamine levels in fish samples to ensure food quality has been properly maintained during transportation and storage.

Although several techniques to detect histamine exist, they generally require expensive and bulky equipment, as well as the presence of a qualified analyst.

MOLECULES 08/08/20 Development and Validation of a TLC-Densitometry Method for Histamine Monitoring in Fish and Fishery Products

Therefore, the monitoring of histamine content in fish and fishery products is considered to be a crucial measure in the seafood industry. In the present study, a simple and rapid densitometric thin-layer chromatographic (TLC) method for histamine determination in fish samples was developed and validated. The samples were homogenized with 10% trichloroacetic acid and histamine was efficiently extracted. Then, an appropriate derivatization procedure was adopted with dansyl chloride.

Once the derivatization was carried out, the samples were applied to silica gel TLC plates and developed by ascending chromatography with chloroform-triethylamine (6:4, v/v) as the mobile phase. ►▼ Show Figures Figure 1 This is an open access article distributed under the Creative Commons Attribution License which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

The optimal conditions of liquid chromatographic separation and mass spectroscopy of histamine have also been investigated. The linear ranges of the method were 20.0 ÷ 1000 ng/mL, and the corresponding correlation coefficient was 0.9993. Mean recoveries of the analyte at three spike levels (low, medium, and high) were within the range of 98.5% ÷ 102.5% (n = 7). The limit of detection (LOD) and limit of quantification (LOQ) values were 3.83 and 11.50 ng/mL for the fish sauce sample and 4.71 and 14.12 ng/mL for the fish sample, respectively. The influence of the matrix effect on the accuracy, repeatability, and recovery of the method was negligible. 1. 2. 2.1. Int. J. Environ. Res.

The proposed method consists of two successive solid–liquid extractions: one with a dilute solution of perchloric acid (6%) and the second only with water. The instrumental analysis with UHPLC provides a very fast run time (only 6 min) with a retention time of approximately 4 min, a limit of quantification (LOQ) of 7.2 mg kg−1, a limit of detection (LOD) of 2.2 mg kg−1, a recovery around 100%, a relative standard deviation (RSD%) between 0.5 and 1.4, and an r2 of calibration curve equal to 0.9995. The method detected optimal values of the validation parameters and required a limited number of reagents in comparison to other methods reported in the literature. Furthermore, the method could detect histamine in a very short time compared with other methods. ►▼ Show Figures.

The FAO/WHO Codex Alimentarius as well as EU legislation have therefore set maximum limits for histamine in fish and fish products. The analytical methods requested by Codex and by EU are different and concern has been raised that this could lead to disputes in the international trade of seafood.

Ces signes cliniques, peu spécifiques, se manifestèrent quelques heures après la consommation d'espadon fumé acheté sur la côte africaine. La relation entre ces deux événements et l'intervalle de temps réduit qui les sépare permirent aux médecins de suspecter une toxi-infection alimentaire collective probablement d'origine histaminique [1].
