| They increase the elimination of food residues and the insoluble pectic acid stimulates the digestive tract. |
| Total levels of pectic substances may be of concern during cider manufacture with respect to haze formation. |
| Plant cell walls are composed primarily of cellulose microfibrils, hemicelluloses, pectic polysaccharides, and small amounts of structural proteins. |
| Fibre is usually made up of cellulose, hemicellulose, and pectic substances. |
| That layer is eliminated by fermentation, actually a form of digestion in which naturally occurring pectic enzymes decompose the pulp while the wetted seeds are held in tanks for one to three days. |
| The heterogeneous, branched, and highly hydrated pectic polysaccharides differ from hemicelluloses in important respects. |
