The physiologically active, gel-forming fraction of the alkali-extractable polysaccharides of Plantago ovata Forsk seed husk (psyllium seed) and some derived partial hydrolysis products were studied by compositional and methylation analysis and NMR spectroscopy. Resolving the conflicting claims of previous investigators, the material was found to be a neutral arabinoxylan (arabinose 22.6%, xylo...

It is well documented that women are prone to constipation-type symptoms premenstrually. An increase in nonstarch polysaccharide intake of 5.9 g/d in the form of palatable drink has proved to be of symptomatic benefit during the premenstrual phase of the cycle resulting in a significant increase in stool frequency, significant decreases in straining at the end of defecation and feelings of inco...

A new colorimetric method for determining the surface-accessible acidic lignin hydroxyl groups in lignocellulose solid fractions was developed. The method is based on selective adsorption of Azure B, a basic dye, onto acidic hydroxyl groups of lignin. Selectivity of adsorption of Azure B on lignin was demonstrated using lignin and cellulose materials as adsorbents. Adsorption isotherms of Azure...

The biofuel properties of biomass play an important role in achieving their utilization on agro-systems and industries. In this context the biomass waste of maize, corncob husk, and its biochars were taken into account to be investigated by thermogravimetric analysis, thermodynamic parameters for non-isothermal analyses using the Ozawa-Flynn-Wall kinetic isoconversional model in order to compre...

Endophytic bacterial diversity was estimated in Mexican husk tomato plant roots by amplified rDNA restriction analysis and sequence homology comparison of the 16S rDNA genes. Sixteen operational taxonomic units from the 16S rDNA root library were identified based on sequence analysis, including the classes Gammaproteobacteria, Betaproteobacteria, Actinobacteria, and Bacilli. The predominant gen...

A novel pectin was acid extracted from chickpea husk (CHP). CHP presented a 67% (w/w) of galacturonic acid, an intrinsic viscosity of 374 mL/g and a viscosimetric molecular weight of 110 kDa. Fourier transform infrared spectroscopy spectrum of CHP indicated a degree of esterification of about 10%. The CHP-calcium system formed ionic gels with a storage (G') modulus of 40 Pa and gel set time (G'...

The effect of ispaghula husk on colonic motility of the right and left side was examined in 10 patients with left sided diverticular disease using an untethered pressure sensitive radiotelemetry capsule. After treatment, ispaghula husk reduced mouth to rectum transit by a median of 8.8 hours and the time to midtransverse colon by five hours. In the right colon there was an increase in the media...

Anthocyanin is a powerful natural antioxidant. Purple corn husk is rich in anthocyanin. In this paper the antioxidative effect of anthocyanin-rich purple corn husk extract (PCHE) in mayonnaise during storage was studied. The antioxidative effect of the mayonnaise containing PCHE was evaluated by measuring peroxide values, p-anisidine values, total oxidation values, acid values, and iodine value...

presence of heavy metals in the aquatic systems has become a serious problem. as a result, therehas been a great deal of attention given to new technologies for removal of heavy metal ions from contaminated waters. adsorption is one of the effective methods for removal of toxic heavy metal such as chromium (vi). in the present study, adsorbent is prepared from rice husk, a low cost by product f...
