| 主权项 | 1. A composition comprising a starch, a biogum and water subjected to heat and shearing sufficient to hydrate and disperse the starch and biogum molecules to produce a pumpable/flowable viscosity stable dispersion having a Brookfield viscosity of less than 20,000 cps (as measured on a Brookfield RVT at 75° F., #5 spindle, 10 rpm) and a starch and biogum solids level of at least 15% dry solids (ds) basis wherein the biogum is gellan. | ||
