AB  - Cereal seeds safety may be compromised by the presence of toxic contaminants, such as aflatoxins.
Besides being carcinogenic, they have other adverse health effects on humans and animals. In
this preliminary study, we used two non‑invasive optical techniques, optical fiber fluorescence
spectroscopy and multispectral imaging (MSI), for discrimination of maize seeds naturally
contaminated with aflatoxin B 1 (AFB 1 ) from the uncontaminated seeds. The AFB 1‑contaminated
seeds exhibited a red shift of the emission maximum position compared to the control samples.
Using linear discrimination analysis to analyse fluorescence data, classification accuracy of 100%
was obtained to discriminate uncontaminated and AFB 1‑contaminated seeds. The MSI analysis
combined with a normalized canonical discriminant analysis, provided spectral and spatial patterns
of the analysed seeds. The AFB 1‑contaminated seeds showed a 7.9 to 9.6‑fold increase in the seed
reflectance in the VIS region, and 10.4 and 12.2‑fold increase in the NIR spectral region, compared
with the uncontaminated seeds. Thus the MSI method classified successfully contaminated from
uncontaminated seeds with high accuracy. The results may have an impact on development of
spectroscopic non‑invasive methods for detection of AFs presence in seeds, providing valuable
information for the assessment of seed adulteration in the field of food forensics and food safety.

AB  - In this preliminary study, we used the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) algorithm to analyze the excitation-emission matrix for different samples of maize flour contaminated with aflatoxin B1 (AFB1) - uncontaminated, low-contaminated, high-contaminated and flour from the local market. We intended to see if there are differences in emission spectral parameters that depend on degree of contamination. The analysis used genuine emission of the fluorophores in the flour, in absence and presence of AFB1, which enables fast screening of the samples, without sample pre-processing. As a result of the analysis, two fluorescence components were derived from the emission spectra for all analyzed samples. The components' positions were the same for the uncontaminated reference sample and the commercial flour sample from the local market, whereas for the samples contaminated with the aflatoxin B1, the emitted peaks' positions were red-shifted. We found that the ratio of the areas of these two components is proportional to the intensity of contamination: 0.071 for uncontaminated sample, 0.090 for the sample from local market, 0.192 for low-contaminated sample and 1.431 for high-contaminated sample. These results indicate that fluorescence EEM coupled with MCR-ALS could be used for rapid and simple estimation of the degree AFB1 contamination in maize flour.
