BACTERIAL CELLULOSE CONCENTRATE AND METHOD FOR TREATING SAID CONCENTRATE

摘要

The purpose of the present invention is to provide a simple and economical method for the production of BC having improved properties such as dispesibility, suspensibility and viscosity. The present invention relates to a method for the improvement of dispersibility and suspensibility of bacterial cellulose, comprising concentrating an aqueous suspension of bacterial cellulose to a final concentration of the bacterial cellulose of between 10 % by weight or more and less than 75 % by weight, dispersing it again into an aqueous solution and homogenizing the bacterial cellulose in the resulting dispersion, to a method for the improvement of paper properties of bacterial cellulose, comprising concentrating an aqueous suspension of homogenized bacterial cellulose to a final concentration of the bacterial cellulose of between 4 % by weight or more and less than 75 % by weight, dispersing it again into an aqueous solution and homogenizing the bacterial cellulose in the resulting dispersion, and to the BC concentrate thus prepared.
