Abstract
The starting product is rich in broken-down plant cell walls. Water is added, if necessary, to obtain a mixture suitable for the subsequent shearing treatment. The product is subjected to a shearing stress before extrusion, to obtain product containing a water-soluble polysaccharide fraction greater than that which exists in nature, without changing the overall chemical composition. The modified product is obtained in the form of crushable aggregates. If the starting product is derived from higher plants naturally rich in pectins, the latter (which have a dry matter content of at least 70%) are extracted from the water-soluble fraction by precipitation by an alcohol or by its multivalent salts. The extraction residue consists of edible fibres.
