ABSTRACT: The use of nitrogen fertilizers in corn crops for silage can improve both production and, theoretically, nutritional quality, especially carbohydrate and protein fractions, thereby optimizing animal production. Thus, the aim of this study was to evaluate the effect of increasing levels of nitrogen fertilization in carbohydrate and protein fractionation on the resulting corn silage (Zea mays L.). Nitrogen fertilization was carried out in the urea form (45-00-00) in V5 stage, at the following doses: T1: 0kg N ha-1; T2: 45kg N ha-1; T3: 90kg N ha-1; and T4: 135kg N ha-1. Crops were harvested at R4 stage and submitted to ensiling in experimental PVC silos. The chemical composition of the resulting silage was evaluated after silo opening. There was no... |

This study evaluates the physical and physicochemical properties of three sugary cassava (Manihot esculenta Crantz) landraces: São Francisco Bag 3, Manicueira 62, and Castanhal Iracema. These three landraces showed high estimated productivity (≥3.93kg plant-1) and had a high sugar content (≥3.92g 100g-1 of root), making them viable for use in syrup production, especially the São Francisco Bag 3 landrace (4.76g 100g-1). The Manicueira 62 landrace had the highest starch content (4.40g 100g-1). The three sugary cassava landraces exhibited high levels of cyanide (>195mg kg-1), indicating the need for processing prior to consumption. |

This study evaluated and compared the effect of the utilization of five different non-conventional starches (chickpea, common bean, Peruvian carrot, sweet potato and white bean) and four different commercial starches (cassava, corn, potato and rice) in pound cake. Common bean starch, followed by Peruvian carrot starch were the non-conventional starch sources that showed tendency to improve the technological quality of pound cake, mainly in relation to corn starch, the most common commercial source. With these sources, the batters presented lower specific gravity and the cakes presented higher specific volume, lighter color, lower crumb moisture reduction during the storage period, and better texture attributes during all the cake shelf-life. Moreover,... |

ABSTRACT: The current research aimed to evaluate the effects of extrusion parameters on the physical characteristics of extruded blends of cassava leaf flour and starch. A factorial central composite design with four independent variables and the response surface methodology were used to evaluate the results of color parameters (L*, a*, b*), water absorption index, water solubility index and paste properties, according to the variations in the leaf flour percentage (1.5 to 7.5%), extrusion temperature (60 to 100ºC), screw speed (175 to 231rpm) and moisture (20 to 30%). Extrusion conditions affect color, water absorption and water solubility indexes and paste properties of blends. The intermediate tested conditions of variable parameters lead to obtain... |

Amylose and amylopectin are the two polysaccharides that constitute starch in bread wheat and the enzyme GBSSI (Granule-bound starch synthase I), also known as waxy protein, is responsible for amylose synthesis in storage tissues. Decrease of the amylose content in starch has been associated with the lack of waxy protein(s). In this work, different sets of PCR markers were used to characterize the genetic variability of waxy loci from 103 Argentinean bread wheat cultivars. For the Wx-A1 locus, Wx-A1a and a novel molecular allele designed Wx-A1g were detected. Wx-B1 locus showed three alleles (Wx-B1a, Wx-B1b, Wx-B1e), and Wx-D1 locus showed only the Wx-D1a allele. Novel single-locus allele specific markers for Wx-A1b, Wx-B1b and Wx-D1b null alleles were... |

ABSTRACT Conventional soil and hydroponic growing systems have inherent differences in water and nutritional availability. These differences may affect plant physiological development and biochemistry. The objective of this study was to evaluate lettuce (Lactica sativa) cv. ‘Crocantela’development in either a hydroponic system or in soil through analyses of vegetative growth; chlorophyll abundance; and sugar and starch content. We evaluated the dry mass (DM), fresh mass (FM), number of leaves (LN), stomatal density and contents of chlorophyll, carotenoids, sugars and starch. Due to the improved nutritional conditions, especially in relation to macronutrients, plants grown in hydroponic system presented significant differences in chlorophyll a (0.4481... |

O amido é uma importante fonte de energia para o milho, sendo o carboidrato mais comum na alimentação humana. A presença de amido favorece a infecção por fungos, entre eles, os produtores de fumonisinas, um metabólito tóxico a humanos e animais. O milho é um componente importantes em sistemas produtivos diversificados, como aqueles em que a soja e braquiárias fazem parte. Entretanto, existem dúvidas se o teor de amido pode ser afetado pelos sistemas de produção e se há relação com as concentrações de fumonisinas. Dessa forma, o objetivo deste trabalho foi avaliar a relação do teor de amido com a concentração de fumonisinas em milho cultivado em três sistemas de produção: a) Sucessão milho no verão/pousio, correspondendo a uma condição de monocultura. b)... |

In order to assess the influence of dietary protein on digestive enzyme expression and cholecystokinin (CCK) content in sea bass larvae, four groups of larvae were fed experimental diets from mouth opening until day 42: three isonitrogenous diets with increasing protein hydrolysate levels (0%, 14% and 46% of crude matter) and one diet incorporating starch. The groups fed high starch or high protein hydrolysate level exhibited the lowest growth. The final weight in these groups was 9.5 and 5.6 mg, respectively, whereas it reached approximately 20.0 mg in the groups fed 0% or 14% protein hydrolysate level. The highest levels of trypsin secretion were observed in larvae fed the lowest protein hydrolysate level. Paradoxically, the groups fed diet containing... |

White breads with Yudane dough (Yudane bread) were made from commercial hard flour by the no first fermentation method. Yudane dough was prepared by mixing boiling water and flour at a ratio of 1:1. The dough at 20 and 40% (w/w, flour base) was added to the total bread dough. In the Yudane bread making method, an extended final proof, lower dough gas retention and gassing power, as well as specific loaf volume were observed compared to conventional bread making (control) without Yudane dough. Also, the moisture content of the Yudane breads increased with increasing water absorption for bread making. The total and reducing saccharide and maltose contents in the water-soluble fraction of Yudane bread also increased with the volume of added Yudane dough. The... |
