Method for reducing colour of a biotechnological liquid |
| 摘要 |
The invention relates to a method for reducing colour of a biotechnological liquid. In the method a biotechnological liquid comprising colour forming substances is obtained and a high-basicity aluminium compound, which has a basicity of at least 0%, is added and mixed to the biotechnological liquid. Precipitate and/or flocks comprising colour forming substances are allowed to form, and the precipitate and/or flocks are separated from the biotechnological liquid. |

1. A method for reducing colour of a biotechnological liquid obtained from enzyme preparation or from preparation of organic acids, comprising the steps of:
obtaining a biotechnological liquid comprising colour forming substances, adding and mixing a high-basicity aluminium compound, which has a basicity of at least 50%, to the biotechnological liquid, allowing precipitate and/or flocks comprising colour forming substances to form, and separating the precipitate and/or flocks from the biotechnological liquid. |
