Caracterización química del aceite de barú y su subproducto de la región noroeste de Minas Gerais, Brasil
This study investigated baru oil and partially defatted baru flour from the northwest region of Minas Gerais, Brazil. The physicochemical characterization of the oil was made by determining the fatty acid profile using gas chromatography, lutein, and α- and β- carotenes by means of high-performance liquid chromatography, and total carotenoids by spectrophotometry. The flour was analyzed for its chemical composition, fiber, and mineral contents. Baru oil presented excellent quality parameters and high contents in unsaturated fatty acids and carotenoids. The flour showed relevant levels of proteins, lipids, and dietary fiber, in addition to having representative mineral contents for food such as manganese, magnesium, and copper. Thus, baru oil and the by-product of its extraction offer a rich chemical composition, and their application may add nutritional value to foods in addition to reducing negative environmental impacts.En este estudio se investigó el aceite de barú y la harina de barú parcialmente desengrasada de la región noroeste de Minas Gerais, Brasil. La caracterización físico-química del aceite se realizó mediante la determinación del perfil de ácidos grasos mediante cromatografía de gases, luteína y α- y β- carotenos mediante cromatografía líquida de alta resolución y carotenoides totales mediante espectrofotometría. En la harina se analizó su composición química, fibra y contenido mineral. El aceite de barú tiene excelentes parámetros de calidad, un buen contenido de ácidos grasos insaturados y carotenoides. La harina presentó niveles relevantes de proteínas, lípidos y fibra dietética, además de tener un contenido representativo de minerales para la alimentación, como manganeso, magnesio y cobre. Así, el aceite de baru y el subproducto de su extracción tienen riqueza en su composición química y su aplicación puede agregar valor nutricional a los alimentos, además de reducir los impactos ambientales
Supergravity brane worlds and tachyon potentials
We study massless and massive graviton modes that bind on thick branes which
are supergravity domain walls solutions in -dimensional supergravity
theories where only the supergravity multiplet and the scalar supermultiplet
are turned on. The domain walls are bulk solutions provided by tachyon
potentials. Such domain walls are regarded as BPS branes of one lower dimension
that are formed due to tachyon potentials on a non-BPS D-brane.Comment: RevTex4, 6 pages; version to appear in Phys. Rev.
