Zusammenfassung: | The present disclosure is related to a process to produce the Beta-glucan polysaccharide whose source is the Saccharomyces cerevisiae yeast by enzymatic proteolysis, which incorporates a cell wall suspension stage coupled with an acid/alkaline extraction with high temperatures, followed by hydrodynamic cavitation in which the flow is passed through a pore size of between 0.8 and 1.2 mm and with a pressure drop of 1.5 atmospheres. This cavitation effect leads to the generation, growth and implosion of bubbles of the solution that flows due to a decrease and subsequent increase in pressure. This effect occurs when the flowing fluid decreases the cross-sectional flow area, causing a speed increase. This speed increase produces a pressure decrease, which upon being below the saturation pressure, achieves that the liquid begins to evaporate and forms bubbles. The collapse of these bubbles is generated with the subsequent pressure increase. Achieving a colored and with functional properties Beta-glucan yeast, with a content with an average concentration of 80% of dry product base and with a solid material particle size with an average of 10 micrometers.
La presente invencion comprende un proceso para producir el polisacarido Beta glucano cuya fuente es levadura Saccharomyces cerevisiae mediante proteolisis enzimatica, el cual incorpora una etapa de suspension de pared celular aunado a una extraccion acida/alcalina con altas temperatura, seguido de cavitacion hidrodinamica en la cual se hace pasar el flujo por un tamano de poro entre 0.8 y 1.2 mm y con una caida de presion de 1.5 atmosferas. Este efecto de cavitacion lleva a la generacion, crecimiento e implosion de burbujas de la solucion que fluye debido a una disminucion y posterior aumento en la presion. Este efecto ocurre cuando al liquido que fluye se le disminuye el area transversal de flujo, lo que provoca que su velocidad aumente. Este incremento de la velocidad produce a su vez una disminucion de la presion, la cual al estar debajo de la presion de saturacion logra que el liquido comience a evaporarse y a formar burbujas. El colapso de estas burbujas se genera con el subsecuente incremento de la presion. Lograndose obtener Beta glucano de levadura con color y propiedades funcionales caracteristicas con un contenido de Beta glucano con concentracion media de 80% base de producto seco con un tama?o de particula del material solido con una media 10 micrometros. |
