One of analytical techniques that enables precise chemical analyzes with speed, low cost and little sample manipulation is near-infrared spectroscopy - NIRS. The interest in NIR spectroscopy has grown remarkably and this technique has been recognized as a powerful tool for quantitative and qualitative analysis of chemical and physical parameters. Besides these features, the methodologies based on NIR spectroscopy have the following inherent properties: 1) allows simultaneous analysis of multi ...Status: Completed Start date: 01/04/2011 |
| Spectroscopy, which is always associated with chemometrics, is a versatile technique that is applied in several areas of science. It is fast, non-destructive, low-cost and, in addition, “clean”, requiring few or no reagents. The latter factor aligns the tool with green chemistry. Status: Completed Start date: 01/03/2013 |

Legislation requirements and consumer demands increasingly push for food safety and quality assurances. Nowadays, generally speaking, quality indicators and contaminants are individually determined in specialized laboratories, which requires long procedures and expensive reagents and makes the analysis of large volumes of samples impracticable. The quick obtainment of analysis results to identify the presence of contaminants and characterize the technological suitability of grains and derivat ...Status: Completed Start date: 01/02/2015 |

This project aims to map degradation levels of cultivated pastures in the Cerrado biome of four Brazilian states (Mato Grosso do Sul, Mato Grosso, Tocantins e São Paulo); to establish computational models to classify degraded pastures in Cerrado areas, according to different levels of degradation; and structure a geospatial database to assist decision making by public and private initiative regarding the use of these lands by agriculture and livestock. Despite being a relevant topic for the c ...Status: Completed Start date: 01/08/2019 |
