PROCESS FOR THE PREPARATION OF PURIFIED BETA-(1,3)-D-GLUCANS

摘要

There is provided a process for the preparation of purified β-(1,3)-D-glucans, comprising the steps of providing an aqueous β-(1,3)-D-glucan initial solution having a pH of above 11.0, filtering the aqueous β-(1,3)-D-glucan initial solution to obtain a β-(1,3)-D-glucan containing filtrate, adjusting the pH of the β-(1,3)-D-glucan containing filtrate with an acid to a pH of below 5.0 to obtain an acidic β-(1,3)-D-glucan solution, and heating the acidic β-(1,3)-D-glucan solution to a temperature in the range of 60 to 160° C.
