“…Moreover, because of their soluble and insoluble dietary fibre contents, each of the components can be used to formulate prebiotic tablets that are beneficial in preventing colon cancer. The components can also be used in slimming formulations because the water-retaining capacity of dietary fibre (especially soluble fibre) is well known for increasing satiety and decreasing nutrient absorption time (GRIGELMO-MIGUEL; MARTIN-BELLOSO, 1999;YUYAMA et al, 2012). In addition, the components can be included in natural formulations to prevent increases in blood cholesterol, because a relationship has been proven between the consumption of dietary fibre and decreases in the intestinal absorption of cholesterol (AJILA et al, 2007).…”

SummaryThe chemical characterization of the pulp, peel and seeds of cocona (Solanum sessiliflorum Dunal) was determined. In artisanal fruit processing, 26.3% of peel and 9.7% of seeds were obtained. The seeds showed a high potential for the development of value-added products because of their dry matter contents ResumoA caracterização química da polpa, casca e sementes de cocona (Solanum sessiliflorum Dunal) foi determinada. No processamento artesanal da fruta foram obtidos 26.3% de casca e 9.7% de sementes. As sementes apresentaram um alto potencial para o desenvolvimento de produtos com valor agregado devido ao seu conteúdo de matéria seca (23,46%), como segue: carboidrato (69,37% base seca (b.s.)), nitrogênio (3,18 g/100 g de sementes, b.s.), K (0,023 g/100 g de sementes, b.s.), Fe (0,0185 g/100 g de sementes, b.s.) e fibra dietética (21,27 g/100g de sementes, b.s.). O teor de carboidrato, fibra dietética e conteúdos minerais da polpa, casca e sementes também evidenciaram o potencial agroindustrial da fruta, visto que estes constituintes podem ser usados para desenvolver alimentos funcionais, aditivos para alimentos, preparações para dietas funcionais e suplementos dietéticos.

“…is a palm native to the Amazon. Its fruits are of economic importance in the Brazilian state of Pará and contain in addition to essential nutrients, anthocyanins, a class of polyphenols to which antioxidant properties have been attributed (Kuskoski et al, 2006;Kang et al, 2011;Gordon et al, 2012;Inácio et al, 2013). Anthocyanins are the predominant polyphenols and account for more than 90% of açai´s total polyphenolic contents (Pacheco-Palencia et al, 2009).…”

Euterpe oleracea Mart. is a palm tree popularly known as açai, which is primarily found in northern Brazil. The açai's fruits contain anthocyanins, a class of polyphenols to which antioxidant properties have been attributed. The aim of this work was to develop O/W sunscreens emulsions containing açai glycolic extract (AGE) and to evaluate both their physical stability and photoprotective efficacy. Emulsions containing AGE and sunscreens were formulated using different types and concentrations of polymeric surfactant (acrylates/C 10-30 alkyl acrylate crosspolymer and sodium polyacrylate). The influence of two rheology modifiers (polyacrylamide (and) C13-14/isoparaffin (and) Laureth-7 and Carbomer) on the stability was also investigated. Physical stability was evaluated by preliminary and accelerated studies. Emulsions with 1.0% sodium polyacrylate were stable and exhibited non-newtonian pseudoplastic behavior and thixotropy. Photoprotective efficacy was evaluated by in vivo Sun Protection Factor (SPF) and determination of Protection Factor of UVA (PF-UVA). When AGE was added to the sunscreen emulsion, no significant increase in the in vivo SPF value was observed. The emulsion containing AGE showed PF-UVA = 14.97, 1.69 of the SPF/PF-UVA ratio and a critical wavelength value of 378 nm, and may therefore be considered a sunscreen with UVA and UVB protection. Euterpe oleracea Mart. é uma palmeira popularmente conhecida como açaí, encontrada no norte do Brasil. O fruto do açaí apresenta em sua composição antocianinas, uma classe de polifenóis à qual é atribuída propriedade antioxidante. Os objetivos desse trabalho foram desenvolver emulsões fotoprotetoras O/A contendo extrato glicólico de açaí (AGE), avaliar a estabilidade física e avaliar a eficácia fotoprotetora. Emulsões contendo AGE e filtros solares foram formuladas utilizando diferentes tipos e concentrações de tensoativo polimérico (acrilates/C 10-30 alquil acrilato polímero cruzado e polilacrilato sódico). A influência de dois modificadores reológicos (poliacrilamida (e) C13-14/isoparafina (e) Laureth-7 e Carbomer) na estabilidade foi avaliada. A estabilidade física das emulsões foi avaliada por meio de estudos de estabilidade preliminar e acelerada. Emulsões com 1,0% poliacrilato sódico foram estáveis, exibiram comportamento não-newtoniano pseudoplástico e tixotrópico. A eficácia fotoprotetora foi avaliada pelo teste in vivo de Fator de Proteção Solar (FPS) e pela determinação do Fator de Proteção UVA (FP-UVA). Quando adicionado o AGE na emulsão contendo filtros solares, não se observou aumento significativo no valor do FPS. A emulsão contendo o AGE apresentou FP-UVA=14,97, a razão FPS/ FP-UVA = 1,69 e o comprimento de onda crítico igual a 378 nm, podendo ser considerado um protetor solar com proteção UVA e UVB.

“…Açaí and blueberry stand out mainly for the presence of red pigments called anthocyanin (Su and Chien, 2007, Kang et al, 2011, Rodrigues et al, 2011Gordon et al, 2012). In addition to anthocyanins, blueberry is an excellent source of quercetin, kaempferol, myricetin, procyanidins, catechin, epicatechin, resveratrol and vitamin C, which contribute to antioxidant activity and bring health benefits to people (Rodrigues et al, 2011;Norberto et al, 2013).…”

The aim of this study was to determine the best extraction conditions of phenolic compounds present in açaí, blueberry and goji berry fruits using the response surface methodology (RSM). The phenolic compounds profile by high-performance liquid chromatography, antioxidant activity was also determined. A factorial 23 design was used to analyze the effect of the solvent (ethanol and water), time (30 and 60 min) and temperature (30 °C and 60 °C) on the extraction of total phenolic compounds (TPC) and activity antioxidant (AA). The variables time and temperature had a positive effect on antioxidant activity (AA) in their highest levels, 60 min and 60 °C, respectively. The solvent ethanol 800 g/mL was more efficient in TPC extracting with AA in all matrices. Rutin was present in high amounts in blueberry and goji berry, and the myricetin in açaí. The açaí showed higher in vitro antioxidant activity when extracted at 60 °C for 60 min. The high correlation coefficient (0.98) of global response (GR) showed that we can find out single and global response in research with multiple dependent variables. The GR analysis indicated the highest values of the TPC and AA when the fruits were extracted at 60°C for 60 min using ethanol as solvent and it was very useful for simplifying and improving the phenolic compounds extraction performance.
