Described herein is a pumpable and/or flowable suspension comprising about 10-60 wt% of beta glucan (BG) that when diluted achieves a filterability ratio less than about 1.5. Further described herein is a pumpable and/or flowable suspension comprising about 10-60 wt% of BG wherein greater than 50% of ultimate viscosity can be recovered after running specified dilution procedure for one pass and greater than 70% of ultimate viscosity after two passes.
