Evaporación osmótica: fundamentos y aplicaciones en la concentración de jugos de fruta

Osmotic evaporation is a modification of traditional processes using membranes; where the effect of a vapor pressure differential, produced by a highly concentrated solution of extraction, water is transferred as vapor through a membrane that acts as a hydrophobic body. This membrane technology is presented as a great alternative for processing exotic fruits, producing concentrates that can be used in the daily diet, being more comfortable to use, reducing transportation costs and increasing the shelf life. This process has many advantages compared to traditional operations, allowing operated at atmospheric pressure and low temperature, ideal for heat-sensitive products.^les^aLa alta demanda de recursos naturales (Suelo y agua) esta dada por el incremento de la poblacion mundial, que requiere areas de expansion urbana, produccion de alimentos y combustibles fosiles que soporten estas y otras actividades del hombre; que contribuyen con la acumulacion de gases de efecto de invernadero en la atmosfera y el cambio climatico. Bajo esta premisa, se vienen investigando en alternativas agropecuarias sostenibles que mantengan la productividad de los sistemas ganaderos, que sean resilientes ante las variaciones ambientales y contribuyan con la mitigacion del calentamiento global. El presente escrito, documenta las principales estrategias de la ganaderia eco-coeficiente; asi como los efectos sobre el cambio climatico.^len^aThe high demand for natural resources (soil and water) is given by the increase in world population, which requires urban expansion areas, food production and supporting these fossil fuels and other human activities; that contribute to the accumulation of greenhouse gases in the atmosphere and climate change. Under this premise, they have been researching alternatives to maintain sustainable agricultural productivity of livestock systems, but they are resilient to environmental changes and contribute to the mitigation of global warming. This written documents the main strategies of eco-coefficient livestock; and the effects on climate change.^lpt^aA alta demanda por recursos naturais (solo e agua) e dado pelo aumento da populacao mundial, que requer areas de expansao urbana, producao de alimentos e apoio a estes combustiveis fosseis e outras atividades humanas; que contribuem para o acumulo de gases de efeito estufa na atmosfera e as mudancas climaticas.
