KEFIRAN PRODUCTION METHOD Russian patent published in 2012 - IPC C08B37/00 

FIELD: food industry.

SUBSTANCE: kefiran production method involves kefiran extraction from kefir fungi in boiling water, the produced solution cooling, kefiran precipitation with an equivalent quantity of ethanol, the solution maintenance, the product drying, extraction is performed (while stirring) in boiling water at a ratio of kefir fungi to water equal to approximately 1:10 during 5-10 minutes till homogeneous mass production. In the process of cooling one adds a proteolytic enzyme and maintains the product at a temperature and pH optimal for the proteolytic enzyme used during no less than 1 hour; the extract cooled to 20°C is filtered through a fine filter; after ethanol precipitation the sediment is filtered, washed with distilled water and repeatedly filtered several times.

EFFECT: invention allows to reduce the extraction period as well as significantly reduce ethanol expenditure with preservation of the produced product high purity.
