| 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. |
| Fibre is usually made up of cellulose, hemicellulose, and pectic substances. |
| Because of their negative charge, pectic polysaccharides bind tightly to positively charged ions, or cations. |
| Plant cell walls are composed primarily of cellulose microfibrils, hemicelluloses, pectic polysaccharides, and small amounts of structural proteins. |
| Some additives include sulfer dioxide, water, oak adjuncts, tartaric acid, sugar, pectic enzymes, gum Arabic, velcorin and mega purple. |
| Total levels of pectic substances may be of concern during cider manufacture with respect to haze formation. |
