“…Silica gel layers seem to be the most common stationary phases used for such investigations. Different mobile phases combined with single, multiple, mono-dimensional or bidimensional development procedures [19,23] were employed depending on the mycotoxins polarity and matrix complexity. Plate documentation was achieved either by measuring the fluorescence emission after UV light (364 nm) exposure or after spraying the plate with different reagents.…”

ABSTRACT. Based on advantages of available modern image processing techniques, thin-layer chromatography combined with image analysis becomes a promising alternative for the mycotoxins determinations in various foodstuffs. For this, the effect of digitizing channel selection and image processing parameters on aflatoxin B2 (AB2) and ochratoxin A (OTA) determination was evaluated and the obtained results were compared with those of classical photodensitometric analysis. The best exciting wavelength for OTA was found to be λ excitation =333nm while for AB2 λ excitation =365nm. Low detection and quantification limits were determined (LOD OTA =0.310ng/spot; LOQ OTA =0.616ng/spot, LOD AB2 =0.557ng/spot, LOQ AB2 =1.098ng/spot). For image processing, the parameter with the highest influence upon the regression calibration curve was brightness and the best digitizing channel was found to be the green one. First-order calibration curve with a good determination coefficient (R 2 >0.99) were obtained on the working range of 2.5-50ng/spot. Although image processing techniques do not provide higher LOD and LOQ values than classical photodensitometry, this method offers the advantage of simultaneous quantification of both mycotoxins.

“…Aflatoxins (AFs) are small molecular weight compounds produced mainly by two fungal species, Aspergillus flavus and A. parasiticus, which are normally occur in hot and humid regions of the world. Recently, a large number of studies focusing on aflatoxin contamination in foodstuffs, mainly in nuts, cereals and spices, have been reported in many countries, especially those in Africa and Asia (Bankole, Adenusi, Lawal, & Adesanya, 2010;Ding, Li, Bai, & Zhou, 2012;Ok et al, 2007;Soubra, Sarkis, Hilan, & Verger, 2009).…”

Aflatoxins are among all known mycotoxins, the most widespread source of contamination of food and feed throughout the world. In aquaculture and aqua-feed formulations the increased use of plant based materials has intensified the risks of aflatoxicosis in farmed fish because of the high load of aflatoxin by the vegetable sources. The aflatoxins production by toxic fungal strains can take place in the field directly, during different processing stages like insiling, aqua feed formulation, preparation and due to improper feed storage. However, the thermal treatments can only destroy the fungus but have no effect on the heat-resistant mycotoxins present in mycelium and spores of the mold. So, the aflatoxin accumulation in fish meal and fish feed represents a great threat for the aqua-cultured species and ultimately for the consumer's health and safety. Consequently, the issue of aflatoxin contamination in fish and aquaculture industry has intensified. This review focused on the deleterious effects of aflatoxins in fish and aquaculture and the possible remedy by the use of adsorbents.
