Despite agri-business's great importance, our principal products are exported in the form of commodities, without any quality specification. In order to commercialize them with quality attributes, it is necessary to make use of processes of quality determination and certification, at low costs, so that the price of the analyzed product won't rise significantly. Thus, it is necessary to develop ultrafast sensors that allow the analysis of thousands of samples an hour and non destructively, which don't cause damage to the analyzed product. Some research groups have been working in the development of technologies for the analysis of agro-industrial products in a non-destructive manner and at high-speed, based especially in spectroscopic and imaging techniques. Among these techniques, our research group has been focusing in the development of nuclear magnetic resonance (NMR) of low resolution which have potential for the analysis of oil quantity and quality in thousands of samples an hour, also of its fat levels in hundreds of parts an hour, and even in the identification of orange plants with citrus sudden death disease. The most important goal of this research project is the evaluation and adaptation of a commercial system of development of new analysis methods for agricultural products such as seeds, fruits, meats and its by-products, by NMR in low resolution, with the techniques of CPMG and CWFP pulse among others.
