| This study assessed the antioxidant, total phenolic, and physicochemical properties of in vitro Terminalia Catappa Linn (locally called castanhola) using the DPPH assay. The castanhola fruits had an average weight of 19.60 ± 0.00 g, combining shell, pulp, and seed weight, and a soluble solids content of 8 °Brix. The chemical composition was determined with predominance of carbohydrates (76,88 ± 0,58%).The titration method was used to determine Vitamin C content using 2,6-dichlorophenolindophenol (DCFI), known as reactive Tillmans resulting in no significant levels. Aqueous extracts of castanhola pulp showed a higher concentration of phenolics, 244.33 ± 18.86 GAE.g-1 of fruit, and alcoholic extracts, 142.84 ± 2.09 GAE.g-1 of fruit. EC50 values of the... |

| Sementes de cupuaçu (Theobroma grandiflorum (Willd. ex Spreng.) K, Schum.) são recalcitrantes e requerem conhecimento sobre os fatores que afetam a manutenção da qualidade. Assim, o objetivo desse estudo foi avaliar os efeitos do teor de água das sementes e da temperatura do ambiente na manutenção da qualidade das sementes em três ensaios. Inicialmente foram avaliados os efeitos do dessecamento na qualidade das sementes; posteriormente, os efeitos das temperaturas de 10°C, 15°C e 20°C foram avaliados sobre as sementes armazenadas por períodos de zero, cinco, 10, 15, 20 e 25 horas; finalmente, os efeitos dos graus de umidade (59,4%, 51,6%, 42,4%, 35,4% e 28,7%) e das temperaturas (20°C e ambiente não controlado) em sementes acondicionadas em sacos de... |

| Os objetivos deste trabalho foram verificar a estabilidade, as correlações e os parâmetros fenotípicos e genotípicos nas cultivares Fhia-1, Fhia-18, PV-0344, Thap Maeo e Caipira em características vegetativas, produtivas e de desenvolvimento da Sigatoka-negra. Após três ciclos os resultados indicaram presença de maior contribuição genética nas características avaliadas, exceto em severidade da doença na décima folha (SEV10), folha mais jovem infectada e número de folhas viáveis (NFV), com maior contribuição ambiental e da interação genótipos com anos; plantas mais vigorosas e desenvolvidas demonstraram ser mais produtivas, pois apresentaram correlações entre as características vegetativas e de produção positivas, enquanto as com SEV10 foram negativas.... |

| Fruits of five regional selections of rambutan (Nephelium lappaceum L.) were characterized to identify those with international marketing quality to promote their propagation in Mexico, improvement and conservation in germoplasm bank. The fruits were harvested in June, July, and August 2008 and, after each harvest, were assessed for shape (length/diameter), firmness, fruit weight, number of fruits per kilogram, weight and percentage of pericarp, seed and aril, total soluble solids, total sugars, vitamin C content, pH, and titratable acidity. In addition, a sensorial evaluation was carried out with 31 panelists who graded each selection for color, sweetness, and acidity. Fruits of five selections were ovoid, and with the following characteristics: firmness... |

| O bacurizeiro (Platonia insignis Mart.) é uma planta frutífera que apresenta madeira com boa característica físico-mecânica e suas sementes podem ser utilizadas para extração de óleo. Este trabalho objetivou avaliar diferentes tratamentos de desinfestação de explantes radiculares de bacurizeiro para o seu estabelecimento in vitro. Segmentos radiculares foram lavados com água destilada e detergente, em seguida foram seccionados em estacas de 1,5 a 2,0 cm, as quais foram imersas em álcool 70% (v/v) por 1 minuto e em soluções de hipoclorito de sódio a 0,50, 1,25 e 1,75% (p/v), durante 20 e 30 minutos. Metade das estacas foram imersas em solução antifúngica (carboxin 0,067% p/v + thiram 0,067% p/v, carbendazim 0,17% p/v, clorotalonil 0,17% p/v +... |

| The objective of this study was to develop pitanga nectar formulations in which sucrose was replaced with different sweeteners. Consumer tests were conducted with 50 fruit juice consumers, and a just-about-right scale was used to determine the ideal pulp dilution and ideal sweetness with sucrose. Furthermore, the adequate concentrations of six sweeteners were determined to obtain the equivalent sweetness of sucrose using relative to these concentrations the magnitude estimation model with 19 selected assessors. The ideal dilution test resulted in 25% pulp, and the ideal sweetness test, 10% sucrose. Sweetener concentrations to replace sucrose were 0.0160%, 0.0541%, 0.1000%, 0.0999%, 0.0017%, and 0.0360%, respectively, for sucralose, aspartame, stevia 40%... |

| ABSTRACT Healthy eating is associated with the consumption of fruits, which are notable for their beneficial effects on human health. The aim of this study was to evaluate the proximate composition, composition of fibers and components with antioxidant activity in soursops varieties Crioula, Lisa and Morada of physiological maturity (PM) and mature (M). The protein, lipid and moisture contents did not differ between soursop varieties, but the ash contents were higher in the Morada-PM (0.56%±0.03) and the Morada-M (0.82%±0.10) varieties. The Crioula-M variety showed higher levels of total dietary fibre (5.76%±0.12). The Lisa-M variety showed higher levels of insoluble dietary fibre (4.46%±0.00). The Lisa-M variety also showed a higher level of phenolic... |

| The objective of this study was to verify the effect of drying on germination of cupuassu (Theobroma grandiflorum (Willd. ex Spreng) K. Schum.) seeds. Desiccation was in forced air oven, with temperature ranging from 23 to 33ºC. Sowing was carried out at 0.5cm of depth in plastic trays in sand and sawdust mixture (1:1), previously sterilized in hot water (100ºC), during 2h. Seeds were left to germinate in a laboratory with no temperature and relative humidity control, under natural light. It was quantified the seed moisture content, in four replications of 10 seeds; the germination percentage, performed during 30 days, with daily counts of the number of germinated seeds; the germination speed index; and number of days to the germination onset. The... |

| The presence of dietary fiber (DF) in the food matrix of some tropical fruits plays an important role in the release and absorption of its bioactive compounds, such as phenolic compounds (PCs). The aim of this study was to evaluate the effect of the DF fractions in mango cv. ‘Ataulfo’, papaya cv. ‘Maradol’ and pineapple cv. ‘Esmeralda’, on the bioaccessibility of their PCs and antioxidant capacity (AOXC) under an in vitro digestion model. The highest PCs content and AOXC was found in mango (274.30 mg GAE/100 g FW), followed by papaya (212 mg GAE//100 g FW), and pineapple (107.63 mg GAE/100 g FW), respectively. About 50% of the total PCs in all fruits was released at gastric phase, increasing closer to 60% at intestinal phase in mango and pineapple.... |
