Propriedades de pasta e concentração de amido resistente em duas variedades de féculas de raízes de mandioca em diferentes estágios de desenvolvimento

The objective of this work was to analyze the profiles of the concentrations of resistant starch and respective properties of paste of two cassava varieties with different development stages. For the evaluation of the profile of the concentration of resistant starch and paste properties, the starches of the cassava varieties were used IAC 576/70 and Fécula Branca, which were collected with different times of cultivation (10, 11, 12, 13, 14 and 15 months), and the use of these times were according the crop of cassava variety IAC 576/70. For the analysis of paste property the apparel was used RVA and for analysis of resistant starch the enzymatic method was used. The results showed for the paste properties happened significant differences among the two varieties of cassava starch, and in some months they there wasn't differences, and as the results of resistant starch happened differences among the starches the months of July and August, and as for the different development stages only the starch of Fécula Branca that happened significant differences.

Influências naturais e antrópicas na qualidade da água subterrânea de poços de abastecimento público na área urbana de Marília (SP)

This work evaluated the natural and anthropogenic influences on the quality of groundwater from public supply wells in the urban area of Marília, São Paulo State. Sixteen sampling points were established in the Adamantina Aquifer, Bauru Aquifer System, analyzing the following parameters: electrical conductivity, temperature, pH, total suspended solids, HCO3 - , PO4 3-, SO4 2-, Cl- , F- , N-NO3 - , Ca2+, Na+ , K+ , Mg2+, Si4+, Fe3+ and Al3+. The results indicated that the groundwater in the urban area of Marília has a slightly acid pH and low conductivity, with the ionic composition presenting a low cation and anion concentration and is classified as soft water and calciumbicarbonated water. Natural sources of elements/compounds can be attributed to the dissolution of carbonates during the water/rock interaction, controlling pH, alkalinity and electrical conductivity, and hydrolysis of other mineral constituents of sedimentary rocks from Adamantina Formation, with the exception of quartz. High concentrations of N-NO3 - found in some public supply wells in urban Marilia were due to sewage.

Tipo de cimentação em materiais duros do perfil de alteração da mina de fosfato da Anglo American, Catalão-GO

One of the main challenges in the mining sector at present, related to the optimization of mineral assets, consists in to find the best proportion of each geological material to be mined and homogenized to ensure high productivity and stability in ore processing plants. The stability of a mineral processing plant is factor for achieving operational excellence, as a stable performance of the plants ensures economy and adherence to financial planning businesses. Is already well Know that the feed rate of the processing plants is dependent on the hardness and quality of the ore. Therefore, the ore behavior predictability is the solution to ensure the stability of mineral processing plants. This work was developed in Anglo American Phosphate Brazil Ltda., at the Fazenda Chapadão Phosphate Mine, located in the southeastern portion of the state of Goiás, in the municipalities of Catalão and Ouvidor. The phosphate ore is the result of supergene apatite concentration in the weathering profile of the alkaline ultramafic phlogopitized rocks, intruded by foscoritic and carbonatitic rocks series. The weathering profile has about 100 meters thick and is divided into three basic types, from top to bottom, coinciding with decreasing intensity of weathering: oxidized ore, micaceous ore and weathered rock. In each portion of this weathering profile, mainly near the contacts between these three divisions, are hard materials, cemented by minerals such as apatite, quartz, goethite, monazite and barite. The different features presented by these materials makes to be vital the correct identification, quantification and location of different hard materials in the mine area, to maximize its use. The main objective of this study was to define the type of cementation of hard materials which predominates in each portion of the weathering profile in the mine, as well as their relationship with the protolith. The work involved geological mapping, channel sampling...

Composição química e propriedades de pasta de farinhas de mandioca

This work aimed to analyze the chemical composition and paste properties of cassava flours, from several producers and classifications, marked in different Brazilian cities. Flours were characterized to moisture, ash, fibers, protein, lipids, total sugars and starch. The paste properties were analyzed in RVA. The results showed significant differences to chemical components in cassava flours. The moisture ranged from 4.39 to 10.26, starch (82.19 to 88.90%), ash (0.48 to 1.07%), fiber (3.23 to 6.41%), protein (1.15 to 2.13%), total sugar (0.05 to 0.56%) and lipids (0.40 to 1.24). These differences can be due the variations of raw material and process. The paste properties of flours were different, with viscosity peak ranged from 73.33 to 387.08 RVU, breakdown (2.42 to 248.83RVU, final viscosity (154.92 to 275.5 RVU) and retrogradation tendency (50.75 to 132.5 RVU), showing the influence of kind of processing on flour viscosity.

Propriedades de pasta e térmicas de misturas instantâneas de farinha de soja, fécula e farelo de mandioca

The application of extrusion technology in the food industry has enabled the development of new commercial products of fast preparation, and maintaining the nutritional characteristics after the process. During this process there are changes in raw material due to the action of temperature, humidity and mechanical friction resulting in a modified product which can be used in various industrial applications. This work aimed to evaluate the effect of the composition of the raw material and operating conditions of the extrusion process on the properties of paste and thermal properties in the development of a functional instant flour of cassava and soybean. The results showed significant effects of all operating parameters on the rheological properties studied. The extruded flours showed no residual gelatinization enthalpy, suggesting that the starch in the samples was gelatinized. The experimental conditions of the smallest percentages of cassava residue (10%) and high soybean flour (25%) mixed with cassava starch, extrusion temperature of 75ºC and low screw speed (170rpm) leads to obtain instant flour with desirable characteristics.
