摘要
Readily processed clear fruit juices contain variable amounts of colloidally dissolved pectic substances. Separation of fruit juice polysaccharides by anion-exchange-chromatography yielded mainly arabinogalactans (type II) and rhamnogalacturonans. The addition of small amounts of the residual pectins to colloid free juices resulted in a up to 60 % reduction of the flux rates in micro- and ultrafiltration systems.
