适用范围：This International Standard describes a method for the determination of the total milk-clotting activity of bovinerennet containing only chymosin and bovine pepsin as the active coagulating enzymes on a standard milksubstrate at pH 6,5.To produce accurate results with this method, test samples of unknown origin are to be checked for theabsence 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 offermentation-produced chymosin.
