The objective of the research study was to determine the physicochemical properties, fatty acid composition and antioxidant activity of the oils of the fruits of Oenocarpus bataua "ungurahui" colected in Peru and Brazil during the waxing and waning seasons. The type of study was evaluative with comparative design, having as population the fruits of O. bataua "ungurahui" randomly collected from the national reserve Alpahuayo Mishana, in the department of Loreto-Peru and in the forestal reserve Adolpho Ducke (Ducke Reserve) of Manaus-Brazil. The results obtained for the oil percentage of the fruits collected in the growing season were 17.08% (Peru) and 19.06% (Brazil); in the emptying season 15.41% (Peru) and 18.23% (Brazil). The comparison of the physicochemical results of the oils of the fruits of O. bataua "ungurahui" collected in different seasons (waxing and waning) in Peru and Brazil...

Actualmente existe una tendencia hacia el consumo de alimentos que proporcionen beneficios para la salud, como es el caso de los frutos de palmeras que tienen una gran importancia como fuente de alimento y por su uso como medicinal. En el presente estudio se evaluó y comparó el valor nutricional y la actividad antioxidante de ungurahui (Oenocarpus bataua), sinamillo (Oenocarpus mapora), asaí (Euterpe oleracea) y huasaí (Euterpe precatoria), frutos de palmeras nativas de la Amazonía peruana.  Se analizó la composición proximal y propiedades fisicoquímicas por métodos oficiales, los micro y macro nutrientes por espectroscopia de absorción atómica y la composición de ácidos grasos por cromatografía de gases. La evaluación de la actividad antioxidante se realizó mediante los métodos de DPPH y ABTS. Los cuatro frutos presentaron un buen contenido de proteínas y carbohid...

The search for new protein sources for food formulation is increasing. Black soldier fly (Hermetia illucens) larvae have high levels of protein, good fat content and are rich in essential amino acids, making them an alternative source of dietary protein. In this work, the nutritional properties and metabolomic characterization of black soldier fly larvae meal native to the Peruvian Amazon reared on three organic waste substrates were carried out. The three meals had a high protein content (38.90-44.68%), lipids (26.96-31.01%), as well as a high potassium, calcium and low sodium content. The larvae meal fed with orange bagasse presented the best content of iron and manganese. The fatty acid profile showed a high content of palmitic, oleic and linoleic acids for the three flours. The most abundant essential amino acids in the three meals were leucine, lysine and valine. A total of 48 compo...

Currently there is a trend towards the consumption of foods that provide health benefits, as is the case of palm fruits that are of great importance as a food source and for their medicinal use. In the present study the nutritional value and antioxidant activity of ungurahui (Oenocarpus bataua), sinamillo (Oenocarpus mapora), asaí (Euterpe oleracea) and huasaí (Euterpe precatoria), palm fruits native to the Peruvian Amazon were evaluated. The proximal composition and physicochemical properties were analyzed by official methods, the micro and macro nutrients by atomic absorption spectroscopy and the composition of fatty acids by gas chromatography. The evaluation of the antioxidant activity was carried out using the DPPH and ABTS methods. The four fruits have a good content of proteins and carbohydrates, as well as a high content of K, Cu and Mn. The oils extracted from the fruits have ...
