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...

La Amazonía peruana, uno de los ecosistemas más biodiversos del planeta, alberga numerosas especies vegetales aún poco estudiadas respecto a su potencial funcional. En el presente estudio se evaluó el contenido de fenoles totales, por el método de Folin-Ciocalteu, la capacidad antioxidante, mediante los ensayos de DPPH, ABTS y FRAP, y el potencial inhibidor frente a la α-glucosidasa y α-amilasa, enzimas relacionadas con la diabetes, de 428 extractos hidroalcohólicos preparados a partir de 214 especies de plantas amazónicas, con el fin de identificar especies promisorias para su aprovechamiento biotecnológico. Los extractos mostraron amplias variaciones en el contenido fenólico (18.47–507.53 mg GAE/g) y actividad antioxidante, DPPH (3.93-90.63 %), ABTS (2.10-91.51 %), Valor FRAP (0.01-1.61 %), y una buena inhibición enzimática a concentraciones bajas, con valores superiores...
