A rapid FT-NIR method for estimation of aflatoxin B1 in red chili powder

Determination of mycotoxins in barley grain by FT-NIR Spectroscopy.

“…The PLS calibration method which produced RMSEC of 0.432 and RMSECV of 2.005, was suggested as applicable for quick discrimination of contaminated samples. Tripathi and Mishra (2009) estimated the concentration of aflatoxin B 1 in red chili powder. The RMSECV of their calibrations was in a range of 0.65-1.88 and the number of factor varied from 5 to 10 according to the selected part of spectra.…”

“…Gaspardo et al (2012) assayed fumonisins B 1 and B 2 in milled corn with the concentration of 0.417-11.845 mg.kg -1 . Tripathi and Mishra (2009) prepared a method for quantification of aflatoxin B 1 in red chili powder in the range of 15-500 μg.kg -1 , which can be used for discrimination of contaminated lots before processing.…”

Methods for Detection and Quantification of Aflatoxins

“…This technique has been underutilized for the detection of aflatoxins due to calibration requirements required against standard reference chemical processes (Tripathi & Mishra, 2009). Despite of the aforementioned limitations, this technique has some advantages, such as: fast and easy equipment operation, good accuracy, precision, performing nondestructive analyzes, prediction of chemical and physical sample from a single spectrum parameters from a single spectrum enabling several components to be determined simultaneously based on the use of multivariate calibrations.…”

“…It basically consists of measuring the absorbance of the sample to light whose wavelength varies in the range known as the Near Infrared (NIR). In the work of Tripathi & Mishra (2009) it is found that for the correct quantification of aflatoxins B1 in chili powder network readings were taken in the range of 6900.3 -4998.8 cm -1 and also in the range of 4902.3 -3999.8 cm -1 , excluding the water absorption bands (5155 and 7000 cm-1). Good results were obtained with respect to chemical techniques such as High Performance Liquid Chromatography (HPLC) and Thin Layer Chromatography (TLC), although its detection range is between 15 to 500 mg / kg which is slightly high compared to these techniques.…”

Assessment of the Sensitivity and Accuracy of Immunochromatographic Test Strips in the Qualitative Detection of Aflatoxin Contamination in Peanuts

“…These include Fourier transform near-infrared spectroscopy (Tripathi and Mishra, 2009), a fluorometric method (Holbrook et al, 2000), high performance liquid chromatography (HPLC) (Manetta et al, 2005), liquid chromatography-tandem mass spectrometry (LC-MS) (Edinboro and Karnes, 2005), and enzyme-linked immunosorbent assay (ELISA) (Li et al, 2009b). These methods are accurate, selective, sensitive, and effective.…”
