发明名称 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.
