Estudio Del Proceso De Producción en Continuo De Hidrolizados De Almidón De Yuca Integrando Hidrólisis Enzimática Y Clarificación Con Membranas

Abstract: RESUMENAntecedentes: Los jarabes de glucosa obtenidos a partir del almidón de yuca han sido estudiados debido al alto contenido de almidón que su materia prima presenta (87,67 % base seca). El proceso de producción se realiza convencionalmente por vía enzimática en reactores batch (en dos etapas), seguida de una etapa de clarificación para remover sólidos suspendidos e impurezas insolubles; esta configuración aumenta los costos de producción y lo hace menos productivo. Objetivos: Estudiar el proceso de producc… Show more

“…It shows that for both temperatures evaluated, the permeability decreases with time due to the fouling of the membrane (formation of deposits, adsorption, and pores blocking by proteins), because of work pressure and heat treatment (24)(25)(26). However, for both temperatures the permeate flux stabilized before 2 h of filtration (55.7±3.4 L/m 2 .h) at 50ºC and 70ºC (151.0±6.8 L/m 2 .h) similar to Acosta and Ríos (27) and Díaz-Arenas et al (20) for the same filtration pilot and membranes (cut-off of 0.2µm), but with different feedstock (raw bovine blood and cassava starch hydrolysates, respectively). That indicates that after some filtration time (90-120 min), a stabilization phenomenon is presented in the membrane (28).…”

“…Micro and ultrafiltration experiments were carried out in a laboratory filtration pilot reported by Díaz-Arenas et al (20). These filtrations were developed in two phases, the first phase was performed with membranes of cut-off 0.2 µm, 0.14 m length and V feed of 5 L. The effect of temperature and cut-off was evaluated in this phase.…”
