Abstract

The present invention relates to a sterile-filtered liquid lactase preparation and to a method of sterile filtering a liquid lactase preparation.

Claims (8)

1. A sterile-filtered liquid lactase preparation comprising at least one salt having a monovalent cation, wherein a total concentration of said at least one salt is at least 0.01% w/w, and further comprising a polyol at a concentration of 10-70% w/w.

2. The liquid lactase preparation of claim 1 , wherein the at least one salt is a salt of Na + , K + or NH 4 + .

3. The liquid lactase preparation of claim 1 , wherein the at least one salt is selected among NaCl, KCI, NH 4 CI, Na 2 SO 4 , K 2 SO 4 , (NH 4 ) 2 SO 4 , or a combination thereof.

4. The liquid lactase preparation of claim 1 , wherein the total concentration of the at least one salt is 0.01-5% w/w.

5. The liquid lactase preparation of claim 1 , wherein the lactase has an amino acid sequence which is at least 50% identical to SEQ ID NO: 1.

6. The liquid lactase preparation of claim 1 , wherein the lactase has a C-terminal end corresponding to amino acid 1304 of SEQ ID NO: 1.

7. The liquid lactase preparation of claim 1 , further comprising at least one salt having a divalent cation.

8. The liquid lactase preparation of claim 1 , wherein the polyol is selected from the group consisting of glycerol, sorbitol, monopropylene glycol, sucrose, glucose, galactose, lactose, and combinations thereof.
