| Abstract Ethanol is one of the most promising fuels in Brazil, but its production is centralized in sugarcane cultivation, and is currently in search for other sources alcohol producing biomass to replace sugarcane monoculture. The aim of this study was to study fermentation process variables such as fermentation time (72 and 96 hours), addition of nutrients (with and without addition) and yeasts (dry and fresh organic yeast), employed in ethanol production from two sweet potato (Ipomoea batatas (L.) Lam.) genotypes: UGA 05 and UGA 77. Alcohol evaluation content in °GL was performed in a completely randomized design according to two factorial schemes (22 and 23), and results obtained were analyzed using Design Expert® software version 8. Results of the... |

| This research studies archaeological samples of maize (Zea mays mays) and cassava (Manihot esculenta), from Januaria, MG, Brazil, for samples between 1010 (for the oldest sample) and 570 years (for the most recent) as estimated through radiocarbon dating. Maize cobs were morphologically analysed by using length, basal and apical diameters, largest diameter, number of rows, number of grains per row, and number of grains per row per length parameters. The maize cob length presented increases through time, allowing an increase on the number of seed per cob, but the size of seeds did not vary significantly. Starch present in the reserve organs of the maize and cassava were analysed morphologically through Scanning Electron Microscopy, and compared to... |

| Dois experimentos foram conduzidos para determinar o valor nutritivo e o desempenho de suínos nas fases de crescimento e período total, alimentados com dietas formuladas com silagem de raiz de mandioca contendo ou não soja integral. No primeiro, foram utilizados 15 suínos, distribuídos em delineamento inteiramente casualizado em parcelas (animais) subdivididas no tempo (subparcelas), totalizando cinco tratamentos e seis repetições. Os alimentos avaliados foram silagem de raiz de mandioca (MA), silagem de raiz de mandioca com inoculante (MI), silagem de raiz de mandioca + soja integral (MS) e silagem de raiz de mandioca + soja integral com inoculante (MSI). As silagens apresentaram bons valores nutritivos e o uso de inoculante não foi efetivo para melhorar... |

| Los rumiantes en producción intensiva reciben dietas basadas en maíz o sorgo y en ambos cereales el almidón es el principal componente. Por tanto, se hizo un experimento de crecimiento (50 d) usando 32 borregos Criollos machos (enteros; 21.4 ± 5 kg PV), alojados en jaulas metabólicas individuales, para evaluar una mezcla enzimática amilolítica α-amilasa proveniente de Bacillus licheniformis y glucoamilasa proveniente de Aspergillus niger y un amortiguador (Acid buf®). Los siguientes tratamientos se asignaron al azar a las unidades experimentales (borregos): A) sin enzima ni amortiguador (testigo); B) α-amilasa (ENMEX®; 1.3 g proteína kg-1 sorgo) y glucoamilasa (ENMEX®; 1.3 g proteína kg-1 sorgo) sin amortiguador; C) sin enzima y con amortiguador... |

| ABSTRACT The aim of this study was to quantify and compare the levels of carbohydrates and phenolic compounds and the antioxidant activity in the pulp and peel of 15 banana cultivars in two ripening stages. Four bunches per cultivar were harvested in the pre-climacteric stage, six fruits were used by sample unit. Fruits were analyzed in the pre-climacteric stage and after ripening. Total, reducing and non-reducing soluble sugars, starch, phenolic compounds and antioxidant activity were evaluated. Cultivar and ripening stage influenced all characteristics analyzed. Unripe pulp and peel had small percentage of sugar, but high percentage of starch, especially ‘Terrinha’ and ‘Marmelo’ cultivars. AAB and ABB cultivars presented the highest percentages of... |
