Asaí is a neotropical palm with fruits that are traditionally consumed by native communities in the Amazon. Consumption has increased due to the antioxidant contents. Distribution of this wild Amazonic palm is widespread and it is possible to find more than one species. While in Brazilian forests, E. oleraceae is the most abundant; in the eastern A...
Amazonian fruits exhibit a very remarkable functional capacity due to its organic acid, pigments and polyphenol composition conferring an insuperable antioxidant capacity. Camu-camu (Myrciaria dubia) is a small wild berry from the floodable Amazonian river region and of which the high ascorbic acid content (around 1648 mg/100 g fresh fruit in green...
Asai is a palm tree native to the tropical region of South America which has recently drawn the attention of the scientific community due to its extraordinary antioxidant content (mainly anthocyanins) and consequent beneficial effects on human health. There are two species: Euterpe oleracea Mart. and precatoria Mart., with the latter being poorly s...
Seje is a native palm found in tropical forests. In the Amazon region, the traditional extraction process involves a long cooking process wherein the collected seje fruits stay in hot water until the oil is separated from the mesocarp. The aim of this study was to compare mechanical extraction methods to the traditional one in order to overcome the...
Several studies show that some foods like fruits, vegetables and grains have different percentages of antioxidant compounds. Copoazú is a wild cacao from the Sterculiaceae family, with a very close relation to cacao (Theobroma cacao). The copoazú is a neglected species, which has not been characterized enough in order to establish its industrial us...
Copoazú (Theobroma grandiflorum) is one of the semi-domesticated arboreal fruit species originating from the Amazon region. This fruit has been studied due to the fact that its pulp is used in derivatives for food industries, for example juices, jams and preserves. In addition, Copoazú seeds can be used in a way similar to that of cocoa seeds in ch...
