| Because of their negative charge, pectic polysaccharides bind tightly to positively charged ions, or cations. |
| Some additives include sulfer dioxide, water, oak adjuncts, tartaric acid, sugar, pectic enzymes, gum Arabic, velcorin and mega purple. |
| Ripening of fruit is characterized by changes in solubility of pectic substances resulting in softening of fruit texture. |
| It seems that the total pectic substances remain relatively the same before or after fermentation. |
| 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. |
