ISO 11815 | IDF 157: 2007: Milk - Determination of total milk-clotting activity of bovine rennets
|24 March 2007
|ISO 11815, IDF 157:2007
This standard describes a method for the determination of the total milk-clotting activity of bovine rennet containing only chymosin and bovine pepsin as the active coagulating enzymes on a standard milk substrate at pH 6,5.
To produce accurate results with this method, check test samples of unknown origin for the absence of main milk-clotting enzymes of non-bovine origin by using an appropriate method.
This standard can also be applied to determine the total milk-clotting activity of fermentation-produced chymosin.
Standard only available in English.
