“…Similar result had been observed previously (Laszlo, 1989;Platt and Clydesdale, 1987). According to Laszlo (1989) as well as Thompson and Weber (1981), the ineffective release of endogenous Fe under gastric condition might suggest that the binding mechanism of this mineral might only be partially via electrostatistic interactions.…”

“…These three gastrointestinal sections possess their unique physiological conditions (such as regional pH, ionic strength, and average transit time), which had been found to significantly affect the in vitro mineral binding capacity of DF in numerous previous studies (Laszlo, 1989;Camire and Clydesdale, 1981;Elhardallou and Walker, 1990;Platt and Clydesdale, 1987).…”

Article InformationThis study was carried out to determination of in vitro binding capacity of wheat and barley for Mn, Zn, Cu and Fe. For this reason wheat and barley were chemical analyzed for moisture, protein, ash, ether extract, total carbohydrate, NDF, ADF, ADL, crude fiber, viscosity, cellulose, hemicelluloses, total dietary fiber, and endogenous minerals. Mineral binding capacity of two samples for Mn, Zn, Fe, and Cu under sequential simulated physiological conditions of the stomach, small intestine, and colon was investigated and compared. Barley showed the higher mineral binding capacity in small intestine. Among the minerals, Fe exhibited the highest percentage of binding under the simulated physiological conditions of the small intestine and the lowest percentage of removing occurred in the stomach for both cereals. Cereals had an affinity for Fe>Cu>Zn>Mn.

“…Mineral-binding characteristics have been reported not to be exhibited by high methoxyl pectins alone but also by low methoxyl pectins and lignin [42]. The differences in the mineral-binding characteristics of high and low methoxyl pectins were purported to result from differences in their physical structure rather than differences in the amount of available carboxyl groups [43].…”

“…The rigid gels formed by low methoxyl pectins may exclude solute mobility while water and solute are allowed to distribute interstitially and on the surface of elastic gels formed by high methoxyl pectins [43]. Depression in mineral absorption in rats fed yam bean hull diet may be caused, partly, by its pectic substances.…”

The influence of yam bean hull on rat's mineral metabolism, serum composition and enzymatic activities was investigated. The chemical composition of the bean's hull shows a reasonably high crude protein (11.4%) but very low contents of crude fat (2.6%), phytic acid (82 mg/100 g) and phytin-phosphorus (23 mg/100 g). K and Ca are the major minerals present in yam bean hull. The hull, rich in cell wall polysaccharides, is composed of cellulose (35.4%), non-cellulose fractions made of pectin and hemicellulose put together (41.9%) and lignin (3.6%). The growth and feed conversion efficiency of rats fed yam bean hull diet were significantly better than rats fed pure cellulose and cellulose-free diets. Conversely, the metabolizable energy of yam bean hull diet (16.4 MJ/kg) was significantly (p < 0.05) lower than that of either cellulose-free (17.8 MJ/kg) or pure cellulose diet (17 MJ/kg). The retention of the minerals examined, except for Ca, was lower when the hull was included in diet as compared to the control (fibre-free) diet. The fibre containing diets decreased serum cholesterol, glutamic oxaloacetate transaminase (SGOT) and glutamic pyruvate transaminase (SGPT). Yam bean hull had no effect on packed cell volume and serum total protein.

“…In fact, excess administration of pectin caused morphological abnormalities in the gastric and small intestinal mucosae (9)(10)(11). As a side effect, pectin, chitin and chitosan somewhat disturbed intestinal absorption of minerals and other nutrients (12)(13)(14)(15). Effective measures for hypolipidemia have not been firmly established.…”

SummaryTriacylglycerol is digested and absorbed primarily through the action of lipase in the lingual and pancreatic juices. We used a wheat flour-derived lipase inhibitor to inhibit triacylglycerol absorption from the intestinal tract, and studied the effect on serum lipid concentration. Rats were given free access to high fat diets containing the lipase inhibitor at O (control), 0.05, 0.1 and 0.2% levels for 3 weeks, and their serum triacylglycerol, total cholesterol, and HDL-cholesterol concentrations were measured at weeks 1, 2 and 3. The measured values were significantly lower in the groups receiving the lipase inhibitor than in the control group. The degree of decrease in these respects was roughly dose-dependent. Additionally, the inhibitor intake raised the fecal lipid excretion and lowered the hepatic cholesterol level. It was, therefore, assumed that the inhibition of lipase in the digestive tract interfered with lipolysis and thereby with cholesterol absorption.
