Kefiran, the polysaccharide produced by microorganisms present in kefir grains, is a water-soluble branched glucogalactan containing equal amounts of D-glucose and D-galactose. In this study, the effect of kefiran on the biological activity of Bacillus cereus strain B10502 extracellular factors was assessed by using cultured human enterocytes (Caco-2 cells) and human erythrocytes. In the presen...

In recent years, there has been a strong focus on beneficial foods with probiotic microorganisms and functional organic substances. In this context, there is an increasing interest in the commercial use of kefir, since it can be marketed as a natural beverage that has health promoting bacteria. There are numerous commercially available kefir based-products. Kefir may act as a matrix in the effe...

The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...

Kefiran, which was isolated from kefir grains, used for the fabrication of cryogel-films in presence plasticizers, such as glycerol and sorbitol. Varying concentration ratios exopolysaccharide/plasticizer system were employed process cryogel-film formulation their effect on physical (film thickness, moisture content, solubility) mechanical (tensile strength elongation at break) properties films...

background :  kefir contains lactic acid bacteria ( lactobacillus , lactococcus , leuconostoc , acetobacter and streptococcus ) and yeasts ( kluyveromyces , torula , candida , and saccharomyces ). kefiran is the polysaccharide produced by lactic acid bacteria in kefir.   methods :  kefiran was prepared from milk containing 0.5% fat and 10 grams kefir grains and was separated from kefir by ethan...

Background and Objectives: Kefiran (Kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. Therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. The expansion of mixed systems can propose kefiran and polyvinyl alcohol (PVOH) as a new composite film. Materials and Methods: Solutions of 20 gr...

kefiran is an exogenous microbial metabolite produced mainly by bacteria and fungi during growth. the present study investigated the effects of the addition of 3% kefiran and 3% xanthan on the extensographic characteristics of wheat dough and the shelf life of raised bread. kefir grain was cultivated in a shaking incubator and kefiran extraction was carried using a centrifugal refrigerator. the...

kefiran is an exopolysaccharide produced by microorganisms present in the kefir grains that has several health promoting properties. in this research, physico-mechanical and thermal characteristics of nanocomposite film composed of kefiran-montmorillonite (mmt; 1, 3 and 5% w/w) were studied. results showed that the thickness and the tensile strength of the films increased by increasing the nano...

kefiran, extracted from kefir grains, is a water-soluble, glucogalactan containing almost equal amounts of d-glucose and d-galactose residues. throughout this research, kefiran and xanthan were added at concentrations of 3% (w/w flour basis) to two wheat dough samples to investigate the effects on the rheological and physical properties of french bread. physicochemical properties of wheat and i...
