“…This behavior is uncommon in açai fresh pulp and blackberry (Rubus fruticosus L.) residues, according to values reported by Del Pozo-Insfran et al (2004) and Machado et al (2014), respectively, where the anthocyanin C3Gl is the predominant compound in the extracts. This difference can be explained due to process conditions through which the raw material used in this work was obtained, and the water content in the raw material (Welch et al, 2008;Yamaguchi et al, 2015). Yamaguchi et al (2015) highlighted the presence of C3Gl and C3R in the açai extracts.…”

Yamaguchi et al (2015) highlighted the presence of C3Gl and C3R in the açai extracts. Both compounds contribute biological properties to the extracts such as antioxidant, anti-inflammatory, anti-proliferative and cardio-protective activities.…”

Açai is considered a functional food, and in addition to being a source of energy and fiber, it is a valuable source of bioactive compounds such as anthocyanins, minerals and fatty acids. In the present work, antioxidant-rich extracts from açai pulp were obtained using pressurized liquid extraction (PLE). The effects of the independent variables, including solvent type (pure ethanol and ethanol/water (50:50 v/v)), citric acid (0 and 0.3%, w/w), pressure (20 and 80 bar) and temperature (30 and 60 °C) were evaluated using a full factorial design. The extraction was affected primarily by the solvent type and the citric acid percentage. The results indicate that the maximum overall yield (X 0 ) was 64 ± 9 (%, d.b.) when the process was performed using ethanol (99.5%) and citric acid (0.3% w/w). The maximum total anthocyanin content and anthocyanin recovered from the raw material were 7 ± 1 (mg anthocyanin/g extract, d.b.) and 11 ± 2 (%, d.b.), respectively.

“…In a recent review, was presented comparative results of biological studies between the species E. precatoria and E. oleraceae that showed the antioxidant activities of the fruit pulp of E. precatoria are superior to those of the fruit pulp in E. oleracea. The results suggest that E. precatoria contains strongly water soluble antioxidants that can enter living cells and inhibit ROS (Reactive Oxygen Species) formation, with greater efficacy than those produced by E. oleracea [33]. Import data show that açaí, once totally destined for local consumption, has conquered new markets and become an important source of income and employment.…”

“…Primariamente é processada a polpa do fruto para produzir o suco, ou a polpa congelada, mas pode-se também produzir sorvetes, geleias, doces, licores e néctar, além da extração de corante(SANTANA; LIMA; MOURÃO, 2014). No Equador as raízes da E. oleracea é usada para aliviar a dor muscular; E no Peru são usadas as raízes para problemas renais, úlcera de pele e malária (YAMAGUCHI et al, 2015). O seu uso se estende para essa área da medicina tradicional com diferentes aplicações devido à grande diversidade dos compostos bioativos presentes na planta.…”

RESUMOOs avanços da biotecnologia nas últimas décadas têm transformado a diversidade biológica de mera fonte de matéria prima, em recurso informacional indispensável para o conhecimento científico e tecnológico desta área, em especial na fabricação de produtos ou processos elaborados a partir de espécies de plantas nativas da biodiversidade brasileira. Considerando que as grandes empresas internacionais vêm incorporando ativos da biodiversidade amazônica como matéria prima para o lançamento de seus produtos, este estudo pretende investigar, por meio de informações tecnológicas contidas em uma base de patente, as tendências tecnológicas de processos e/ou produtos relativos a E. oleracea, visando orientar linhas e projetos de pesquisa e de desenvolvimento tecnológico por pesquisadores vinculados a área de biotecnologia aplicada à saúde humana.Palavras-chave: Informação Tecnológica. Biotecnologia. Euterpe oleracea. PROSPECTIVE STUDY OF PRODUCTS AND TECHNOLOGICAL PROCESSES WITH AÇAÍ (EUTERPE OLERACEA)ABSTRACT Advances in biotechnology in recent decades have transformed the biological diversity in a mere source of raw materials and essential information resource for the scientific and technological knowledge in this area, especially in the manufacture of products or processes developed from species of native biodiversity Brazilian plants. Whereas the major international companies are incorporating assets of Amazonian biodiversity as raw material for the release of their products, this study aims to investigate, by means of technological information contained in a patent based on the technology trends of processes and/or products related to E. oleracea, aiming guide lines and research projects and technological development by researchers linked to biotechnology applied to human health.
