Lactase preparation |
| abstract |
A process for the release of lactase from yeast cells comprising contacting the cells with an alkyl alcohol or a dialkyl ketone, followed by extraction of the lactase in an aqueous solution at a pH in the range 5.5 to 8.0 is disclosed. Also disclosed is a process for the selective reduction of protease activity in lactase preparations comprising heating an aqueous solution of lactase containing protease impurities in the presence of glycerol. Lactase stability during the heating process can optionally be enhanced by addition of manganous ion. |
