| Total levels of pectic substances may be of concern during cider manufacture with respect to haze formation. |
| Fibre is usually made up of cellulose, hemicellulose, and pectic substances. |
| Ripening of fruit is characterized by changes in solubility of pectic substances resulting in softening of fruit texture. |
| 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 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. |
| They increase the elimination of food residues and the insoluble pectic acid stimulates the digestive tract. |
