The effects of floral location on the physicochemical and thermal parameters of honey samples from Enugu North senatorial zone were evaluated. Floral location had significant effects (P 0.05) on viscosity, electrical conductivity, sugar content, free acidity, ach content, moisture content, density, pH, colour, thermal heat conductivity and thermal heat diffusivity except, F/G ratio and specific heat capacity. Honeys from Igbo-Eze South were more viscose than the rest of the honey samples from other floral locations, with a mean viscosity value at 25 oC (15.58cSt) higher than that at 60 oC (12.63cSt). The electrical conductivity, ash content, moisture content and density ranged between 226.5 - 211.45 µS cm-1, 0.06 - 0.57%, 16.59 – 22.55% and 0.82 – 1.25 g... |

Production, characterization and development of models for glucose syrup obtained from selected agricultural crops were studied. Glucose syrups were produced at 60, 80 and 100oC. The rheological properties of the glucose syrups were investigated and the effect of temperature on viscosity was determined. Also, the effect of shear rate on viscosity was determined at spindle speeds of 10, 20, 50 and 100 rpm. Data obtained were fitted into Power law model for analyzing the viscosity and for fluid classification. The starch yields were 71.7, 85.3 and 91.5% and the syrup yields were 78.82, 86.35 and 88.65% for maize, rice and cassava respectively. Viscosities of the syrups showed an inverse relationship with temperature and shear rates. The power law index (n)... |

Background: The characterization of the dynamic process of veins walls is essential to understand venous functioning under normal and pathological conditions. However, little work has been done on dynamic venous properties. Aim: To characterize vein compliance (C), viscosity (η), peak-strain (W St) and dissipated (W D) energy, damping (ξ), and their regional differences in order to evalúate their role in venous functioning during volume-pressure overloads. Methods: In a mock circulation, pressure (P) and diameter (D) of different veins (anterior cava, jugular and femoral; from 7 sheep), were registered during cyclical volume-pressure pulses. From the P-D relationship, C, W St and ξ (at low and high P-D leveis), η and W D... |

The aim of this work was to study the effect of improved fermentation on sour cassava starch, aiming to reduce its fermentation time and to enhance its expansion capacity as well as its viscoamylographic properties and its sensorial acceptability. Results showed that the improved process of cassava starch production did not harm starch expansion, physicochemical properties or sensorial acceptability; it also produced starches with different viscoamylographic properties, which compared favourably to those of the sour cassava starch produced through current industrial methods. |

Six polysaccharide-producing bacteria, isolated from soil samples and identified as Pseudomonas and Arthrobacter (Strains 3B, 4B, 7B, 21B, 18E and 21D), were tested for the yield of polysaccharides produced during growth in two culture media: one containing glucose and the other sucrose (1, 2, 3, 4 and 5%). The yield was quantified measuring the viscosity of the broth, using the Poiscuille equation. The effect of temperature and pH of the culture media was investigated. The largest polysaccharide yield was obtained when the concentration of the carbon source was lower than 2%. Glucose and sucrose stimulated the polysaccharide production in a similar way. When the initial pH of the fermentation broth was increased from 5.0 up to 7.0, there was an increase... |

ABSTRACT The intestinal health of piglets depends on the balance between diet, microflora and mucosal integrity. Disruption of this balance can compromise the digestive functions, leading to diarrhoeal frame and decline in performance of piglets. However, the level and type of fibre can limit digestive disorders. Thirty newly weaned piglets were used to evaluate the levels of neutral detergent fibre (NDF) in diets regarding performance, pH, viscosity and concentration of short chain fatty acids of digestive contents, gastrointestinal transit time, morphology of the intestinal mucosa, weights of organs and occurrence of diarrhoea. NDF level had quadratic effect on weight gain and feed conversion ratio of piglets, estimating best results at the level of... |

The objective of the research was to relate the physical and chemical characteristics of soymilk plain beverages to its sensory acceptance. Five commercial products and a new product formulated based on the less accepted sample were used. The overall acceptance was evaluated by 102 assessors using a 10-point hybrid hedonic scale. The hedonic scores ranged from 3.8 (sample E) to 7.0 (A). Most assessors (55%) preferred sample A, which was viscous (26.6 cp), dark (L* = 77.7), and slightly acidic (pH = 6.6). Sample C, which had lower solid content and higher acidity, was preferred by 29% of the assessors. These two beverages showed the greatest commercial potential of the products analyzed. The least-accepted sample (E), preferred by 8% of the assessors, had a... |

Abstract The study was aimed to investigate the effect of different salep properties on ice cream quality parameters. Therefore, salep samples obtained from six different Orchidaceae spp. were examined for glucomannan and starch contents. Statistically significant differences were observed between the glucomannan and starch levels, viscosity values (between 23.90 cP and 430.90 cP), and overrun levels (between % 32.62 and % 42.46) of ice cream mixes and melting qualities of ice cream samples according to species of the salep sample (p < 0.05). It is concluded that high-glucomannan (> 40%) containing salep samples, which were obtained from the species (O. mascula ssp. pinetorum, S. vomeracea ssp. vomeracea) have significantly desired effects on the... |

The physical and physicochemical characteristics of blueberry (Vaccinium myrtillus) fruits produced in Brazil were analyzed. Rheological properties were measured at 5, 25, 45 and 65 °C, on a stress controlled rheometer equipped with grooved a stainless-steel parallel-plate in a shear rate range of 0-300 s-1, with the objective of determining the influence of temperature on the rheological properties. The pseudoplastic behavior with yield stress was well described by the Ostwald-de-Waele (Power Law), Herschel-Bulkley (HB) and Mizhari Berk models. The yield stress and behavior index decreased with the increase in the temperatures for 5, 25, and 45 °C whereas for the temperature of 65 °C the effects were the opposite exhibiting elevated values. The viscosity... |

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... |

A banana assume grande destaque na produção mundial, sendo que o Brasil ocupa a terceira posição da produção. As bananas podem ser consumidas cruas, enquanto os plátanos são consumidos necessariamente cozidos ou na forma de farinhas devido ao seu elevado teor de amido, constituindo assim uma oportunidade interessante para uso como ingrediente na indústria alimentícia. O objetivo deste trabalho foi caracterizar o amido extraído de 12 genótipos, dentre plátanos e bananas, pertencentes ao banco ativo de germoplasma da Embrapa. Os amidos apresentaram teor considerável de amilose (29,7% a 37,8%), baixos teores de fósforo (0,01% a 0,03%) e de lipídios (< 0,1%), larga faixa de temperatura de gelatinização (66,9 ºC a 90,8 ºC), estrutura granular heterogênea com... |

As propriedades térmicas e reológicas do amido são determinantes na qualidade tecnológica deste biopolímero, entretanto essas não são consideradas no desenvolvimento de cultivares de milho no Brasil, não permitindo a apropriação ao diversificado setor agroindustrial. Assim, o objetivo do presente estudo foi caracterizar híbridos de milho quanto ao perfil viscoamilográfico do amido isolado. Os amidos isolados de trinta e seis híbridos de milho, experimentais e comerciais, foram caracterizados em um analisador rápido de viscosidade (RVA), sendo avaliadas as variáveis temperatura de pasta, viscosidade máxima a frio, viscosidade máxima, viscosidade mínima no aquecimento, viscosidade de quebra, viscosidade máxima no resfriamento, retrogradação e viscosidade... |
