适用范围：This International 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, test samples of unknown origin are to be checked for the absence of main milk-clotting enzymes of non-bovine origin by using an appropriate method (e.g. IDF 110B). This International Standard can also be applied to determine the total milk-clotting activity of fermentation-produced chymosin.
