Análise de sementes de Amendoím por meio da técnica RMN

Abstract

This work is part of a project (NMR Project) underway in the Physics department, financed by the UEM research fund, and is mainly intended for the non-destructive selection of oilseeds by means of the NMR technique. On the one hand we have NMR (according to many, the best of all spectroscopic techniques), on the other we have peanuts (an oilseed) and in the middle is quality. This trinomon2 can weigh favorably on the economic balance of our country, given that Mozambique is dependent on agriculture. Nuclear Magnetic Resonance has been used recently in the analysis of the distribution of oleosomes in seeds (Carlton et al., 1996). Agronomists and other peanut specialists are well aware that it is capable, as well as of the numerous applications that it can provide. Nuclear magnetic resonance is the study of the magnetic properties of the nucleus (Shaw, 1984). Thus, in this work, NMR will be used in the analysis of peanuts, and especially of the oil in which it is impregnated. The nucleus that we are interested in investigating in the LTA, at the moment, is the hydrogenoid proton1 H, because it is the largest constituent of the oil and the most studied in NMR. The peanut to be investigated is of the Namitil variety (supplied by INIA) whose oil was extracted in the Chemistry department. Based on the objectives recommended in the TL protocol, practical work was carried out following the general scheme of figure 1.
