Extraction of casein
WebThe casein in milk can also be precipitated by the action of an enzyme called rennin. Rennin is present in the stomach of young calves. However, both the nature of the precipitate and the mechanism of precipitation differ when rennin is used. The precipitate formed using rennin, calcium paracaseinate, contains calcium. WebThe mixture of coagulated casein and solution is placed in two or four half-liter centrifugal bottles and whirled in a centrifuge at a rate of about 1,000 revolutions per minute until the casein settles at the bottom, occupying about one-third of the original volume of the mixture. The supernatant liquid is decanted.
