abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
One of the most important environmental problems is water and soil contamination with heavy metal ions. In this direction, the aim of this investigation was biosorptive removal of Cr (VI) using calcium alginate and determination of isotherm and kinetic of biosorption. Materials and Methods: Using batch system, biosorption capacity of calcium alginate for removal of Cr(VI) ions was investigated...
The purpose of this study was to synthesize biomaterials from daily dental waste. Since alginate impression material contains silica and calcium salts, we aimed to synthesize calcium silicate cement from alginate impression material. Gypsum-based investment material was also investigated as control. X-ray diffraction analyses revealed that although firing the set gypsum-based and modified inves...
Synthetic seeds can use as tool for applied biotechnology methods for improve the quality and increase the production of sunflower. Shoot tips excised from in vitro proliferated shoots were encapsulated in calcium alginate beads. The best gel complexation was achieved using 3% sodium alginate and 100 mM CaCl2.2H2O. Maximum percentage response for conversion of encapsulated shoot tips into plant...
This paper reports a novel formation method of monodisperse calcium alginate microbeads from water-in-oil-in-water (W/O/W) droplets with an ultra-thin oil phase layer. W/O/W droplets containing sodium alginate in an internal aqueous phase were formed as a template of calcium alginate microbeads using a microfluidic device. The ultra-thin oil phase layer of the W/O/W droplets was ruptured by an ...
background and objectives: probiotic yeasts are used in production of functional foods and pharmaceutical products. they play an important role in promoting and maintaining human health. until now, little work has been published on improving the survival of saccharomyces in stimulated gastrointestinal condition. material and methods: in this study the exposure of the yeast in the capsulate and ...
To improve the performance of nanostructured calcium carbonate in gene delivery, a hydrophilic polysaccharide, alginate, was added to calcium carbonate co-precipitation systems to form alginate/CaCO(3)/DNA nanoparticles. The size and ζ-potential of the nanoparticles were measured by a zetasizer. Due to the existence of alginate chains which retarded the growth of calcium carbonate based co-prec...
Pellets of calcium-alginate, calcium-pectinate and calcium-alginate-pectinate were produced via crosslinking in an aqueous medium for site-specific drug delivery in the gastrointestinal tract. A comparative study of their physicochemical characteristics by means of texture analysis, modulated temperature differential scanning calorimetry (MTDSC), scanning electron microscopy and swelling dynami...
To check the suitability of enzyme entrapped beads for use in pharmaceutical industry, amylase enzyme was entrapped in agar/agarose, polyacrylamide gels and calcium alginate beads. Sodium alginate of 1% concentration was found to be best with respect to immobilization efficiency and calcium alginate beads so obtained were not much susceptible to breakage. When sodium alginate- amylase mixture w...
an oral suspension could a suitable dosage form for the geriatric patients. the calcium alginate coated ion exchange resinate of propranolol hydrochloride were prepared using amberlite ir-120 by solvent evaporation. microcapsules of propranolol hydrochloride resinate were prepared by solvent evaporation technique,the suspensions were prepared by using deionised water as the vehicle. methyl cell...
