Process for the extraction of soluble polysaccharides

摘要

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.
