<p>There is provided a process for the preparation of purifiedβ-(1,3)-D-glucans, comprising the steps of providing an aqueousβ-(1,3)-D-glucan initial solution having a to pH of above 11.0, filtering the aqueousβ-(1,3)-D-glucan initial solution to obtain aβ-(1,3)-D-glucan containing filtrate, adjusting the pH of theβ-(1,3)-D-glucan containing filtrate with an acid to a pH of below 5.0 to obtain an acidicβ-(1,3)-D-glucan solution, and heating the acidicβ-(1,3)-D-glucan solution to a temperature in the range of 60 to 160° C.</p> |
