- n. The clear or pale yellow polysaccharide gel exuded by dairy kefir or water kefir grains.
Sorry, no etymologies found.
Kefir grains contain a water soluble polysaccharide known as kefiran that imparts a rope-like texture and feeling in one's mouth.
The kefiran in kefir has been shown to suppress an increase in blood pressure and reduce serum cholesterol levels in rats.
Milk sugar is, however, not essential for the synthesis of the polysaccharide that makes up the grains (kefiran), and scientific studies have demonstrated that rice hydrolysate is a suitable alternative medium.
