POTENTIAL OF NEAR INFRARED SPECTROSCOPY-NIR ALLIED THE MULTIVARIATE ANALYSIS FOR GEOGRAPHICAL DISCRIMINATION OF BURITI (MAURITIA FLEXUOSA L.) AMAZONIAN OIL
Journal Title: Periódico Tchê Química - Year 2017, Vol 14, Issue 27
Abstract
Pulp oils from buriti fruit (Mauritia Fleuxosa L.), from the Amazon region, were obtained from different locations of the state of Roraima - Brazil, for the application of Near Infrared Spectrometry with Fourier Transform (FTNIR) (PCA) and Hierarchical Cluster Analysis (HCA) as a methodological alternative for geographical discrimination of buriti collection points, which has been the focus of research related to bioactive compound compositions and presented potential for oil extraction for use in the fuel, pharmaceutical, cosmetic and food industries. In total, twenty samples of these oils were analyzed in the 700 to 2000 nm range, and processed through application PCA and HCA . In both cases the potentialities of the techniques were confirmed, obtaining satisfactory results for the geographic identification of the oils collected in the places of Boa Vista, Mucajaí, São João da Baliza and Caroebe, with a data description of up to 99.77% by PCA. Which demonstrates the effectiveness of the methods for discriminations without destruction of the samples and in real-time, useful in the efficient monitoring of healthy and safe products to consumers.
