Sweetening syrup production by enzymatic hydrolysis of starch variety yam (Dioscorea rotundata)Producción de Jarabes Edulcorantes por Hidrólisis Enzimática del Almidón de Ñame Variedad (Dioscorea rotundata)
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
Sweeteners syrups produced by enzymatic hydrolysis from starch of hawthorn yam (Dioscorea rotundata). The starch was extracted by a scratched, washed, sedimented and drying; the yield was quantified taking into account the amount of initial raw material and was determined the concentration of starch, amylose, amylopectin, crude fiber, ash, protein, fat and humidity in accordance with the requirements of the AOAC ...
Optimizing conditions for the development process of the sponge liquid bread mold through a factorial designOptimización de las condiciones de proceso para la elaboración de la esponja líquida de pan de molde a través de un diseño factorial de experimentos

The bread in its many forms is one of the oldest and most widely food consumed by humanity, its appearance is not known for sure, but it is presumed that he was in the Middle East, where he began to cultivate wheat. Due to its development in different cultures have been many developments in technology and industry, however all the processes that are designed to make bread have had a common purpose and simple, the ...
Treatment of vinasses - recirculationEl tratamiento de las vinazas – la recirculación
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
The purpose of this minireview is to give an overview of treatments that have been applied on the vinasse, residue from the alcoholic fermentation; appoint some of its advantages and disadvantages, and then submit recirculation, as one of the best options from an economic point of view and easy implementation, for those who are not interested in the ethanol byproducts.
General Vision of Phytoremediation Treatment for Sludge Derived of WastewaterVisión General Sobre el Proceso de Fitorremediación en Lodos Provenientes de Ptar
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
Wastewater coming from industrial processes requires special treatment either physical and/or biological. Their resulting problem is the sludge being produced, whose components are mainly inorganic with some organic content, and in the most unfavorable case, with the inclusion of toxic contents, i.e. heavy metals. In certain industries, the problem has to do with the accumulation of sludge in containers, before being ...
“Standardization of the pre cleaning of sugar cane juice for farms sugarcane san marcos-sucre”Estandarización de la pre limpieza del jugo de caña de azúcar para las estancias paneleras de san marcos-sucre
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
Panela production in Colombia is 1'587 .893 tons / year, which represents 538.905 million pesos for 2002, figures that make this country the second largest producer of panela. Changing eating habits and lifestyle of the population, and the rapid social and technological developments that humanity is experiencing, are a threat to the survival of this agro-industry, which is still at an early stage of development, despite ...
Improving the process of dehydration uchuvaMejoramiento del proceso de deshidratación de uchuva
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
In the drying of food is essential to know the time required to achieve the dry bulb temperature, with the goal of reducing energy consumption without affecting product quality. Appropriate estimate is required to determine in advance the heat transfer coefficient by forced convection between air and product. In this paper we developed a procedure for a drying system in the form of Gooseberry hemispherical and four ...
¿A quantitative biophysics ethics to address the global challenge?¿Una ética biofísica cuantitativa para enfrentar el desafío global?
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
Philosophical and political discussions often become ends in circles, in which barely scratches occur without creating new structures of thought that would reveal the reality and the ways to solve the serious problems we live. Generally, each person involved in the discussion, consider that it is right in his argument and no mediator to interact in the discussion to help move the points of view, nor an arbitrator may ...
Enhanced Engineering Teaching Through Computational Fluid Dynamics SoftwareMejoramiento de la Enseñanza en Ingeniería a Través de Software de Dinámica de Fluidos Computacional
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
The chemical reaction engineering course, one of the cornerstones of chemical and even environmental engineering programs, has been taught through introductory courses that do not necessarily have into account non-ideal reactors concepts, which are the basis for the analysis of many real systems such as reservoirs and aerated lagoons. In this work, a strategy to enhance the reaction engineering teaching by means of ...
Law enforcement fick and peleg model for study of water uptake in navel cargamanto yellow (phaseolus vulgaris l.) and peas seca (pisan sativa) during rehydrationAplicación de la ley de fick y el modelo de peleg para estudiar la absorción de agua en el frijol cargamanto ombligo amarillo (phaseolus vulgaris l.) y la arveja seca (pisan sativa) durante la rehidratación
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
This research validated Fick’s Law and Peleg’s model applicability for modeling water sorption of yellow navel cargamanto bean (Phaseolus Vulgaris L.) and dry pea (Pisum sativum), using five different water temperatures 25, 35, 40, 47 y 55 ºC, to soak the analyzed materials; for bean an optimal mathematical expression was obtained to make estimations, opposite case was the observed thing for pea; the diffusion coefficient ...
Mathematical modeling of alcohol distillation columnsModelación Matemática de Columnas de Destilación Alcohólica
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
New evaluation modules are proposed to extend the scope of a modular simulator oriented to the sugar cane industry, called STA 4.0, in a way that it can be used to carry out x calculation and analysis in ethanol distilleries. Calculation modules were developed for the simulation of the columns that are combined in the distillation area. Mathematical models were supported on materials and energy balances, equilibrium ...
