SE PUEDEN EXTRAER POLISACARIDOS SOLUBLES, TALES COMO PECTINA Y CARRAGEENINA, DE UN MATERIAL VEGETAL HACIENDO PASAR UN FLUIDO DE EXTRACCION A TRAVES DE UN LECHO FIJO DEL MATERIAL VEGETAL QUE CONTIENE POLISACARIDOS PARA HIDROLIZAR Y EXTRAER SIMULTANEAMENTE EL POLISACARIDO DEL MATERIAL VEGETAL Y SEPARAR LA SOLUCION QUE CONTIENE POLISACARIDOS DEL RESTO DEL MATERIAL VEGETAL SOLIDO. NO ES NECESARIO LLEVAR A CABO UN PASO DE FILTRACION. SE PUEDE AÑADIR OPCIONALMENTE UNA SUSTANCIA DE RELLENO AL MATERIAL VEGETAL PARA AUMENTAR LA VELOCIDAD DE PERCOLACION DEL FLUIDO DE EXTRACCION A TRAVES DEL LECHO. Soluble polysaccharides such as pectin and carrageenan are extracted from vegetable matter by passing an extraction fluid through a fixed bed of the polysaccharide-containing vegetable material to simultaneously hydrolyze and extract the polysaccharide from the vegetable material and separate the polysaccharide-containing solution from the remaining solid vegetable material. No separate filtration step is required. A filler can optionally be added to the vegetable material to increase the rate of percolation of the extraction fluid through the bed.
