  • 2.  Kefir is viscous, acidic and mildly alcoholic milk beverage ( <2%)  The word kefir is said to have originated from the Turkish word "Keif" which means "good feeling“.  Kefir dates back many centuries to the shepherds of the Caucasus Mountains who carried milk stored in leather pouches where it would ferment into fizzy sour yoghurt.  Elie Metchnikoff, a Nobel-prize winning biologist at the Pasteur Institute, first suggested that lactobacilli might counteract the putrefactive effects of GI metabolism in 1908.  He attributed the long and healthy life of the people of the Caucasus Mountains to their consumption of soured milk.  In modern times there's a great deal of interest and research into Probiotics and the health giving properties of fermented milks like kefir.

  • 3.  Kefir grains are white or cream colored grains that look rather like cauliflower florets that ferments milk.  The kefir grain is an inert polysaccharide matrix in which a relatively stable and specific microbial community species coexists in a complex symbiotic relationship. (more than 30 microflora)  After the fermentation, the grain is recovered and can be reused.  When culture ferments the milk these structures grow, creating new grains in the process  Modern Kefir cultures have reduced the yeast fermentation, resulting in less CO2, ethanol and foam, LAB ACB Yeast Fermented food and beverage of the world – Jyoti prakash tapang and KK

Streptococcus cremoris & diacelilactis same properties Increase desirable flavor of kefir and CO2. Lactobacillus casei Creates a favorable environmental for the desirable microbial balance Limits lactose intolerance. Contributes to Immunity Leuconostoc cremoris Produces lactic and acetic acid acetyl-methyl carbinol and diacetyl, two aromatic agents of kefir. Lactobacillus plantarum inhibits microorganisms which cause spoilage Adheres to intestinal mucosa Source - www.kefir.net; www.lifeway.net; ww.liberte.qc.ca;www.medicinalfoodnews.com
  • 5. A) BIOMASS PRODUCTION  At industrial-scale 100- 3,000-L bioreactors, leading to the development of a process for granular kefir biomass production.  Aerobic fermentation with whey as the carbon source.  Yield 79 g/L final kefir biomass (0.89 g/g of lactose utilized), in 7 h of fermentation time. B) MAKING OF KEFIR MILK Sequence :http://www.ncbi.nlm.nih.gov/pubmed/15688361 Fat standardization (3.5%) Homogenizing (one stage, 175 barg at 70°C) Heat treatment (95°C for 4 min.) Inoculation of starter culture Fermentation Cooling and filling http://www.nda.agric.za/docs/AAPS/Arti cles/Goats/Dairy%20Goat/mmgmilk.pdf

  • 8.  Kumis, a mildly alcoholic drink made from fermented mare’s milk  It is the popular national beverage of Kazakhstan.  Been widely known since ancient times. Avicenna (Ibn Sina), the 11th century great philosopher and physician praised its therapeutic effects a thousand years ago  From ancient times, Eastern Arabs processed their musalla (wine); western slaves made their own wine, and kazakhs in deserts decanted their kumis.  Kazakh kumis has its own peculiarities since the others were made of fruit, say, from grapes or pomegranates http://web.ics.purdue.edu/~aaldaber/kumis.html
  • 9.  Mare’s milk contains less casein and fatty matter than cow’s milk.  Kumis presents a dispersed coagulum giving the product a smoother taste as compared to kefir  A higher alcohol content (up to 3%) than in kefir.  Production of higher carbon dioxide levels is also a characteristic of kumis.  Acetic acid bacteria are not found in kumis  Kumis is dried and preserved for many seasons.  In kumis distinctive starters are transferred from one generation to another within families for back-slopping.

  • 10.  Unlike kefir, the culture exist in liquid state.  It is made by adding the culture to mare's milk while stirring or churning. A) LAB  Acidification and the final sensorial properties of the product (Ying et al. 2004, Watanabe et al. 2008, Wu et al. 2009) B) YEAST  Turn it into a carbonated and mildly alcoholic drink.
