A beta -lactamase composition intended for the treatment of milk. According to the invention it contains beta lactamase having an activity, determined on a nitrocefin substrate, of approximately 100 - 10,000 U/liter of milk to be treated, a buffer in an amount sufficient for buffering the pH value of the composition to 6 - 8, a stabilizing agent for preventing the inactivation and/or precipitation of the beta lactamase during cold storage, and an indicator for the identification of milk treated with the composition. The enzyme preparation is suitable for use for the treatment of even large raw milk batches of up to tens of thousands of liters. The milk ir corresponding product treated with the enzyme preparation can be given, for example, to calves as a drinkable fodder, or it may be used as a raw material for fodder. |
