Abstract
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.
Claims30
A process for the extraction of soluble polysaccharides from solid vegetable material comprising percolating an extraction fluid through a fixed bed of a polysaccharide-containing vegetable material mixed with a filler to simultaneously hydrolyze and extract the polysaccharide from the vegetable material and separate a polysaccharide-containing solution from the remaining solid vegetable material.
A process for extracting a polysaccharide from solid vegetable material comprising percolating an extraction fluid through a fixed bed of polysaccharide containing solid vegetable material in a direction countercurrent to direction of movement of the fixed bed to simultaneously hydrolyze, extract, and separate the polysaccharide from the vegetable material.
