“…Being capable to detect different types of mycotoxins in a simple test sample, TLC has been widely used for quantification and identification of aflatoxins in various food samples at ppb level [18][19][20][21][22]. Thus, for each test sample, multiple mycotoxins can be detected by this method.…”

The detection and determination of aflatoxins at nanogram level is important from human health point of view. Aflatoxins exhibit acute toxicity demonstrating teratogenic, mutagenic and carcinogenic effects. Amongst the available aflatoxins, B1, B2, G1, G2, M1 and M2 have been the more frequently analysed aflatoxins by chromatographic, spectroscopic and immuochemical methods. Because of the presence of aflatoxins at trace level in food and feedstuff used for human and animal consumption, new analytical methods have been designed for sensitive and selective detection and quantification of aflatoxins. Each of the employed analytical methods, described herein, such as thin layer chromatography, high performance liquid chromatography, gas chromatography and immunochemical methods, among others, has inherent merits and demerits in aflatoxins analysis. This chapter critically examines each of the analytical methods currently in use in the analysis of aflatoxins. Deviating from the earlier approaches, this chapter focuses on the need of methodologies that have negligible environmental impact. Though most of the existing methods are highly sensitive and reasonably safer to use but still there is the need of development of new green methodologies focusing on the reduction of solvent consumption, replacement of environmentally hazardous solvents with more benign alternatives, miniaturization of instrumentation and solvent-free sample preparation.

“…Using TLC, it was possible to determine several types of mycotoxins (e.g., aflatoxins, ochratoxins, patulin, tremorgenic toxins, zearalenone, citrinin, sterigmatocystins, versicolorins, etc.) in one sample, aflatoxins being detected in a range as low as 1 to 20 ppb [ 67 , 68 ]. Usually, the quantification of AFM 1 is performed by its UV fluorescence, using an excitation at 360 nm and emission at 435 nm [ 67 ].…”

Aflatoxins, which are mainly produced by Aspergillus flavus and parasiticus growing on plants and products stored under inappropriate conditions, represent the most studied group of mycotoxins. Contamination of human and animal milk with aflatoxin M1, the hydroxylated metabolite of aflatoxin B1, is an important health risk factor due to its carcinogenicity and mutagenicity. Due to the low concentration of this aflatoxin in milk and milk products, the analytical methods used for its quantification have to be highly sensitive, specific and simple. This paper presents an overview of the analytical methods, especially of the electrochemical immunosensors and aptasensors, used for determination of aflatoxin M1.

Planar chromatography (PLC) is gaining importance in the analysis of natural products. Sophisticated instrumentation has become available in this field. Major progress in planar chromatography has been achieved through the development of forced-flow techniques. Progress has also been made in the capillary-controlled flow techniques with the use of modified development chambers. A large variety of stationary phases is available and strategies to optimize mobile phase compositions in PLC have been developed. The detection and quantitation in PLC has improved through direct coupling of PLC with spectroscopic methods with and the use of modern, computerized scanning densitometers.
