| It seems that the total pectic substances remain relatively the same before or after fermentation. |
| The process consists of two parts, first an acid treatment to hydrolyse the pectic substances in the albedo, and then an alkaline treatment to disintegrate and eliminate the rest of the peel. |
| Because of their negative charge, pectic polysaccharides bind tightly to positively charged ions, or cations. |
| The heterogeneous, branched, and highly hydrated pectic polysaccharides differ from hemicelluloses in important respects. |
| The two major classes of cell wall matrix polysaccharides are the hemicelluloses and the pectic polysaccharides, or pectins. |
| Total levels of pectic substances may be of concern during cider manufacture with respect to haze formation. |
