Characterization of Commercial Pectin Preparations by Spectroscopic and Chromatographic Techniques.
<p>Pectin has a long history as a food additive. However, elucidation of its fine structural and property relationships remains elusive. Recent research has focused on pectin's ability to complex with divalent heavy metals to aid in characterizing it. Commercial pectins of unknown composition were …

The bioavailability of folic acid in pectin - coated fortified rice in humans using stable isotope techniques
… losses in fortified rice, in particular pectin (Shrestha, 2003). However, pectin, an indigestible fibre, may entrap or bind added folate, decreasing its absorption efficiency. Healthy volunteers (n=26, 18-39 yrs) received oral 400μg [13C5]PteGlu doses in three separate test meals in …

On the role of pectin methylesterases in the development of the non-vascular land plant model Marchantia polymorpha
… this thesis, we examine how the gene family of pectin methylesterases (PMEs) contributes to the development of the non-vascular plant Marchantia polymorpha. Pectin is a highly abundant component in the cell walls of land plants and charophyte algae. From angiosperms, we know that the …

Development and characterization of edible films made from four dietary fibers -pectin, guar gum, locust bean gum, and hydroxypropyl methylcellulose
… dietary fibers, e.g., guar gum, locust bean gum, pectin, and hydroxypropyl methylcellulose, and glycerol concentration to the mechanical properties and dissolution/ partial dissolution time of their films and the viscosity of their solution. Specifically, it investigates if the higher glycerol and …

Evaluation of Prebiotic Fibers and Pectin on Probiotic Strains and Effect of Bacteriocin-like Substance on the Survival of Listeria Monocytogenes
… the health benefits of higher molecular weight pectins have not been fully evaluated. According to reviews, pectins are fermented in the large intestine due to the cooperative activities of colonic bacteria with complementary enzymatic activities. There are very few studies that demonstrate the …

Effects of modified bioactive pectins on colon cancer cells in vitro
Pectin is a complex structural polysaccharide present in the cell walls of terrestrial plants, fruit and vegetables. Modified pectin (MP), pectin treated with pH, heat or enzymes, has been shown to have anti-cancer activity in several cancer cell lines. The galactan chains of MP are postulated to …
