Pectin

Pectin any of a group of water-soluble carbohydrate substances that are found in the cell walls and intercellular tissues of certain plants In the fruits of plants pectin helps keep the walls of adjacent cells joined together Immature fruits contain the precursor substance protopectin which is converted to pectin and becomes more water-soluble as ripening proceeds

The effect of pectin on swelling and permeability

The potential of pectin as a bacterially degradable polysaccharide for colon drug delivery has been demonstrated Due to the high solubility and swelling properties of pectin in aqueous media it is frequently used in combination with water insoluble polymers for targeting drugs to the colon The aim of this study was to evaluate free films

Preparation and Characterization of Pectin Hydroxamates

Specifically the pectin derivatives with more hydroxamic acids were shown to have enhanced water solubility even two-fold higher than that of the native pectin Thus the introduction of hydroxamic acid into the pectin structure seemed to be a useful tool for improving the functionality of pectin Author Biographies In Young Bae Department of Food and Nutrition Hanyang University 17

Preparation and functional properties of soy hull pectin

The pectin yield increased from 7 68 to 13 73% as the hull/solvent ratio increased from 1∶10 to 1∶15 Changes in pectin yield for higher hull/solvent ratio were insignificant (16 31–13 28% for 1∶20–1∶25 ratio respectively) The hull/extraction solvent ratio did not significantly affect the pectin content and degree of esterification Diffuse reflectance Fourier transform infrared

The Applications of FoodPec™ Pectin [Foodchem Own

Pectin is divided into water-soluble pectin and water-insoluble pectin according to its solubility The solubility of pectin is related to the degree of polymerization of pectin and its methoxyl content and distribution Although the pH temperature and concentration of the pectin solution also have a certain effect on the solubility of the pectin in general the smaller the molecular weight
