OF PLANTS FROM THREE REGIONS OF THE SAVANNA FROM GOIÁS STATE. 2009. 55 f. Dissertação (Mestrado em Ciencias Agrárias - Agronomia) - Universidade Federal de Goiás, Goiânia, 2009.http://repositorio.bc.ufg.br/tede/handle/tde/1441The aim of this study was to evaluate the influence of different regions (East, West and Southeast) of the Goiás state in the nutritional composition and the protein quality of the roasted baru almond (Dipteryx alata Vog.), produced in 2008. One hundred and fifty newly fallen fruits were collected of six plants, in each region. The almond was removed from the fruits, roasted and was analyzed for centesimal composition, mineral content and amino acid profile. The indexes Amino Acid Score (AAS), Protein Digestibility-Corrected Amino Acid Score (PDCAAS) and the Net Protein Ratio (NPR) were determined to evaluate the protein quality. A biological assay was carried out with 36 Wistar rats, which were assigned into six treatments for fourteen days in standardized climate conditions. The diets were formulated according to the American Institute of Nutrition (AIN-93G): diet with casein and 7% lipids (reference); diet with casein and 14% lipids (control); diet with baru almond from East region; from West region; from Southeast region; and protein-free diet. The pair feeding procedure was adopted to control the consumption of diets of animals. The results were submitted to analysis of variance and test for comparison of means (Tukey, p <0.05). The baru almond from the three regions showed a high protein (31 g. 100 g-1), lipids (41 g. 100 g-1) and energy (532 kcal. 100 g-1) contents, with no significant differences between the three regions. The almond also showed a high content of fiber (12 g. 100 g-1), iron (3 mg. 100 g-1) and zinc (3 mg. 100 g-1). It was found significant differences in the amino acid profile between the regions assessed, and the amino acid valine was the first limiting in the three regions (AAS between 77% and 89%). The value of PDCAAS of the almond protein from the West region (73%) was higher than the Southeast region (64%). The NPR index was similar between the three regions (relative NPR = 71%). The origin region of the baru did not influence the nutritional composition, but caused differences in amino acid profile of the almonds. The almonds are rich in lipids, protein, fiber, iron and zincapplication/pdfAcesso Abertocumaru, Dipteryx alata Vog., Cerrado, valor nutritivo, aminoácidosDipteryx alata Vog., Savannah, nutritive value, amino acidsCNPQ::CIENCIAS AGRARIAS::CIENCIA E TECNOLOGIA DE ALIMENTOS::TECNOLOGIA DE ALIMENTOSDissertação
