Kefiran is a water-soluble polysaccharide extracted from kefir grains biomass. The identification and quantification of kefiran monosaccharides were carried out by HPTLC after the complete acid hydrolysis of kefiran solutions. The mobile phase was a mixture of n-propanol: acetic acid: water (70:20:10, v/v). For derivatization was used p-aminobenzoic acid and o-phosphoric acid in methanol. The identified HPTLC fractions were glucose (Rf 0.71) and galactose (Rf 0.66), which indicates a high purity of the extracted kefiran. The relative concentrations of each monosaccharide identified in samples are dependent on the initial molecular weight of the polymer chain. The kefiran isolated from kefir grains grown in milk is a heteropolysaccharide which contains D-glucose and D-galactose units in a ratio of 0.94:1.1. [less ▲]

Kefiran is a microbial and water-soluble polysaccharide obtained from the flora of kefir grains. It contains approximately equal amount of D - Glucose and D - Galactose, which could improve the viscosity and viscoelastic properties of dairy products. Kefiran has some functional advantages such as antibacterial, antifungal and antitumor properties, it is often used in the food industry as a texturing and gelling agent. The matrix of kefiran can produce films with good appearance and satisfactory mechanical properties; it appears to have excellent potential as a film-forming agent and it can be an affordable alternative to synthetic packaging in food applications.
