Food Control. 72, 110-122 (2017). Review of the methodologies reported on mycotoxin analysis in Sub-Saharan Africa. The review highlights the analytical methods reported for monitoring of toxic contaminants in food and feedstuffs, including references on the application of TLC and quantitative densitometry. _x000D_

Food Chem. 239, 865-871 (2018). NIR spectroscopy for the analysis of oleic, palmitic, linoleic, linolenic, omega-3 and omega-6 acids, unsaturated and saturated fatty acids, and triacylglycerides was compared with HPTLC and GC methods. HPTLC of polar (1) and neutral (2) lipids in salmon oil on silica gel with methyl acetate – isopropanol – chloroform – methanol – potassium chloride (0.25 % solution) 25:25:25:10:9 for (1) and with n-hexane – diethyl ether – glacial acetic acid 35:15:1. Detection by dipping into primulin reagent (10 mg primuline, 40 mL water, 160 mL acetone) for 2 s. The NIR method permits the simultaneous quantification of several fatty acids, but the accuracy and robustness of the method remain at the screening level for palmitic and linolenic acids and monounsaterated fatty acids. The method is not sensitive enough to detect low concentrations of fatty acids, therefore direct measurements on salmon tissue samples were not considered. The NIR method requires a previous extraction of the lipids, similar to the chromatographic techniques. Still the NIR method is a fast, direct and not destructive technique for salmon oil sample screening purposes.

CBS 117, 5-7 (2016). HPTLC of amylase-produced dextrins and standards glucose, maltose, maltotriose, maltotetrose, maltopentose, maltohexose, and maltoheptose on silica gel with acetonitrile – acetone – water 3:3:2 with chamber saturation to a migration distance of 60 mm. Detection by immersion into aniline-diphenylamine-phosphoric acid reagent (2 g diphenylamine and 2 mL aniline in 80 mL methanol in 10 mL 85 % phosphoric acid, made up to 100 mL with methanol) followed by heating at 120 °C for 5 min. Evaluation under white light. Quantitative determination by absorbance measurement at 500 nm. Evaluation in the polynomial working range of 40-210 ng/band.

J. Chromatogr. A 1558, 69-76 (2018). Development of an HPTLC method for monoacylglycerols (MAG), diacylglycerols (DAG), triacylglycerols (TAG) and free fatty acids (FFA) in E 471 food emulsifiers, as a simple, rapid, sensitive and convenient screening alternative to HPLC and GC analysis. HPTLC of the samples in t-butyl methyl ether on primuline pre-impregnated LiChrospher silica gel by two-fold development, first with diethyl ether to 18 mm, then with n-pentane – n-hexane – diethyl ether 13:5:7 to 75 mm. Quantitative determination by fluorescence measurement at UV 366/>400 nm, using the cumulative signal for each lipid class and 1,2-distearin for calibration. The amounts of the lipid classes were calculated using response factors and expressed as monostearin, distearin, tristearin and stearic acid. The LOD and LOQ for 1,2-distearin were 1 and 4 ng/zone, respectively. The visual detection by fingerprint enabled an easy characterization and the direct comparison of emulsifiers through the lipid class pattern.
