Enzymatic process for the treatment of xanthan gums to improve the filtrability of their aqueous solutions |
摘要 |
The filtrability of xanthan gum aqueous solutions is improved by an enzymatic treatment in two successive steps, the first step by means of a polysaccharase and the second step by means of a protease, the operating conditions of each step being such that the corresponding enzyme is active in said step.
