This study investigates the influence of pectin fine structure (i.e. methyl ester content and distribution) on the rheological properties of calcium induced pectin networks. The methyl ester distribution was assessed using the definition of the degree of blockiness (DB) and absolute degree of blockiness (DBabs). The study showed that 1) the ability to form calcium induced pectin networks depend...

Twelve young adult (1.7 +/- 0.1 yr) male cats were used in a replicated 3 x 3 Latin square design to determine the effects of fiber type on nutrient digestibility, fermentative end products, and fecal microbial populations. Three diets containing 4% cellulose, fructooligosaccharides (FOS), or pectin were evaluated. Feces were scored based on the 5-point system: 1 being hard, dry pellets, and 5 ...

The main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. Pellet cores of budesonide were prepared by extrusion / spheronization technique. Pectin, in different ratios was combined with Eudragit RS30D, Eudragit NE30D or Surelease to produce film coating. The dissolution profiles of pectin coated pellets were investigated in pH of 1.2 (2 ...

Pectin has been shown to minimise the fall in blood glucose seen in patients who are troubled by hypoglycaemia attacks after gastric surgery. We therefore performed 50 g glucose tolerance tests with and without 14.5 g pectin on 11 post-gastric surgery patients. After pectin, the high postprandial levels of glucose, insulin, and enteroglucagon were significantly reduced as was the fall in blood ...

The complex carbohydrates apple pectin, citrus pectin, flaxseed mucilage, blood group A substance, gum acacia, and gum myrrh as well as an extract of RBC, when examined in a pattern test, were shown to inhibit the agglutination of chicken RBC by influenza A virus. A number of other simple and complex carbohydrates showed no inhibitory effect. The hemagglutination-inhibiting action of apple pect...

Pectin, a major component of the primary cell walls of dicot plants, is synthesized in Golgi, secreted into the wall as methylesters and subsequently de-esterified by pectin methylesterase (PME). Pectin remodelling by PMEs is known to be important in regulating cell expansion in plants, but has been poorly studied in cotton. In this study, genome-wide analysis showed that PMEs are a large multi...

To stabilize air-water interfaces, as in foams, the adsorption of surface-active components is a prerequisite. An approach to controlling the surface activity of proteins is noncovalent complex formation with a polyelectrolyte in the bulk phase. The molecular properties of egg white ovalbumin in a complex with pectin in the bulk solution and at air/water interfaces were studied using drop tensi...

(1) We investigated the trophic effect of pectin on the intestinal mucosa injured by formyl methionyl-leucyl-phenylalanine (FMLP), a chemoattractant produced by the intestinal bacterial flora. (2) We first demonstrated that oral administration of FMLP for 7 days reduced the disaccharidase activities and increased the permeability, measured by fluorescein-isothiocyanate-conjugated dextran, of ra...

The instability of polysaccharide/protein mixtures occurs because of either thermodynamic incompatibility or complexation. We studied which instability mechanism dominated given the external conditions. Therefore the effect of temperature, pH, and biopolymer concentration on the phase separation of pectin/caseinate mixtures was investigated. At pH > 6, thermodynamic incompatibility with spinoda...
