In this study, research, articles, translations, Aspergillus spp., peanut, were characterized in common colonists, classified and quantified using FTIR ATR accessory coupled with spectral data of infected FTIR-ATR. peanut samples were preprocessed (mean-centering, smoothing the 1st derivative), for the PLS regression analysis and used for Very high R2 values results. quantitative (99.98% 96.20-) together with low error values of RMSEC (0.014 – 0.153 Log of peanut CFU/g) were obtained, Even the spectrum of peanut. matrix was dominant at early stages of invasion (≤ 2.5 Log CFU/g peanut), resulting in separation section (from Nigri Flavi) and at higher population (> 4 Log CFU/g, species level separation (Aspergillus alliaceus, Aspergillus flavus, Aspergillus parasiticus, Aspergillus caelatus, and Aspergillus tamari) was observed increased The accuracy of classification correct. proportionally with fungal invasion and 100% correct classification level was reached when the cell level was 4.5-5. CFU/g = Log Samples with similar secondary metabolites (toxin producers) grouped in close-by diagrams for all levels of PC score fungal growth. the possible implementation of Results highlight FTIR-ATR model to detect early stages of infected peanuts even at invasion; besides, the potential to prove separation capability in terms of species and their secondary metabolites.
