Determinação de macro e micro nutrientes de frutos de Moringa oleífera Lamark (parede interna e externa da casca) e sementes. 2017. 120f. Dissertação (Mestrado em Química) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2017.https://repositorio.ufrn.br/jspui/handle/123456789/24004The Moringa oleifera Lam is a tree of Indian origin with several utilities in the areas of pharmaceutics, fuels, water purification and mainly food. The plant has a better development in dry climates. The culture of use as food is very broad in some African countries and with widespread expansion in Latin and Asian countries because of its rich nutritional value. In this work were realized the determination of macro and micronutrients of the internal and external wall of the bark, and seeds of two Moringa trees of the same species, but of different localities, existents in the UFRN and EAJ to determine the contents of moisture, ash, proteins, fats, carbohydrates, fiber and metals. Make a comparison between these and, if possible, compare with other analyzes made with the plant from other locations. The two samples were divided into three parts each: internal and external wall of the shell, and seeds, where they were sprayed and kept in polyethylene containers. After preparation of the samples, were carry out moisture and ash determinations, lipid extraction by Soxhlet, Proteins, by the Kjeldahl method. Fibers, with the equipment to determine fibers. Some metals (Ca, Co, Cu, Cr, Fe, Mg, Mn, Mo, Ni, K Se, Si, Na e Zn) by ICP-OES, in addition to making FTIR-ATR and TG/DSC. The results obtained showed an optimum lipid content in the seeds (29,26 - 35.83 %), while in the inner and outer wall of the shells, the contents were low compared to seeds (0,4 – 1,2 %). Protein contents had a high value in the seeds (30,46 and 34,57%), while the internal and external walls of the peels had a much lower content (3,54 – 6,53%). The fiber contents of the seeds (64,19 – 70,76%), of the internal and external wall (72,18 – 85,59%). Carbohidrate contents had a high value in the internal and external part of the bark (70,89 – 82,72%), while in the seeds the contents were low (19,41 – 29,09%). The metals found in the seeds of the two samples were Ca, Cu, Fe, Mg, Mn, K, Na and Zn and the metals found on the inside and outside of the bark were Ca, Cu, Fe, Mg, Mn, K, Na, Si and Zn. The mean of the results of the analyzes was submitted to the paired Student t test, with 95% significance to know if there was a significant difference or not. The results found are important for comparisons with future research for camparisons with future research, of trees of the same species from other localities and different environments, and also to elaborate a nutritional table of seeds and moringa shells for future use.Acesso AbertoMoringa oleífera LamSoxhletKjeldahlMacro e micro nutrientesTeormasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICA
