A simple method was developed for fast identification of pectin, based on a recombinant endopectate lyase cloned from Aspergillus niger. When pectin was demethylated and treated with pectate lyase, beta-elimination occurred, resulting in a double bond between C-4 and C-5 in the galacturonic acid residue of the released nonreducing end. The formation of double bonds produced an increase in light...

The mechanical and disintegration properties of paracetamol tablets formulated using Delonix regia seed gum (DRSG) as a binder have been studied in this work. Acacia BP (ACG) and tragacanth BP (TRG) were used as official gum standards. The mechanical properties, i.e. tensile strength (TS) and brittle fracture index (BFI), showed that with an increase in concentration of the gum binder, the tens...

This paper describes a method for reliably identifying saccharide materials in paintings. Since the 3(rd) millennium B.C., polysaccharide materials such as plant gums, sugar, flour, and honey were used as binding media and sizing agents in paintings, illuminated manuscripts, and polychrome objects. Although it has been reported that plant gums have a stable composition, their identification in ...

Four trials were conducted using 86, 24-h-old pigs to evaluate the utilization of medium-chain triglycerides (MCT). Effects of emulsification and amount of MCT fed were examined. After a 4-h period during which feed was withheld, pigs were force-fed MCT (containing 75% octanoate and 25% decanoate), marking time 0 of the experiment. Blood samples were obtained at 1 and 2 h for subsequent medium-...

OBJECTIVE Natural honey (NH) and Nigella sativa (NS) seeds have been in use as a natural remedy for over thousands of years in various parts of the world. The aim of this study was to assess the protective effects of NS (Nigella sativa) and NH (natural honey) on acetylsalicylic acid induced gastric ulcer in an experimental model with comparison to Cimetidine (CD). STUDY DESIGN Experimental, c...

Food powders were applied on crackers that had been coated using water, oil, emulsion, sucrose, or hydrocolloid solutions. The hydrocolloids that were used include gellan gum, kappa-carrageenan, methylcellulose, gum karaya, gum tragacanth, gum arabic, guar gum, modified starch, and maltodextrin. Solutions of similar hydrophobicity to the powder gave the greatest adhesion. NaCl, barbecue (BBQ), ...

In this study, new antimicrobial hydrogels were prepared via reaction of functionalized-tragacanthgum (TG) biopolymer by quaternary ammonium functionalization of TG (QTG) with acrylic acid(AA). Characterization of the QTG hydrogels (QTG-AA) was carried out by FTIR,thermogravimetric analysis (TGA), and 1H NMR. Dynamic mechanical analysis, (DMA) wasconducted to characteriz...

During this study, we report the green synthesis of  magnetic copper ferrite nanoparticles using tragacanth gum as a reducing and stabilizing agent by the sol-gel method. The green synthesized CuFe2O4 MNPs are characterized by powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy...

this study investigated the effect of carboxymethyl cellulose (cmc), tragacanth, and saalab hydrocolloids in two concentrations (0.3 and 0.7%) and different frying media (refined canola oil (rco), rco+1% bene kernel oil (bko), and rco+1 mg l-1 unsaponifiable matter (usm) of bko on acrylamide formation in fried potato slices. the hydrocolloid coatings significantly reduced acrylamide formation i...
