    • A clear Reb D solution is prepared by adding Reb D powder to water and heating to completely dissolve the Reb D powder, or by extracting Reb D from stevia plant using hot/boiling water or water/ethanol, wherein the temperature of the clear Reb D solution is above 70° C. Ideally, the clear Reb D solution is mixed with a solubilizing enhancer, wherein the temperature of the enhanced Reb D solution is maintained above 70° C., and wherein the solubilizing enhancer is a hydroxyl-containing sweetener. A stabilizer is then added to the Reb D solution to produce a stabilized Reb D solution; wherein the stabilizer comprises a thickener or anti-agglomeration agent. The stabilized Reb D solution is spray dried to form a powder. The solubility of Rebaudioside D is enhanced in water-based fluids, in particular in beverage concentrates and syrups 1.
    • 通过将Reb D粉末加入水中并加热以完全溶解Reb D粉末,或通过使用热/沸水或水/乙醇从甜菊植物提取Reb D,制备清晰的Reb D溶液,其中清除Reb D的温度 溶液高于70℃。理想地,将澄清的Reb D溶液与增溶增强剂混合,其中增强的Reb D溶液的温度保持在70℃以上,并且其中增溶增强剂是含羟基的增甜剂。 然后将稳定剂加入到Reb D溶液中以产生稳定的Reb D溶液; 其中稳定剂包括增稠剂或抗附聚剂。 将稳定化的Reb D溶液喷雾干燥以形成粉末。 在水性流体中,尤其是饮料浓缩物和糖浆1中,莱鲍迪苷D的溶解度得到提高。

    • A composition comprising a polymer that is a reaction product of: a copolymer backbone comprising; (i) at least one acrylamide component, (ii) at least one co-monomer, (iii) at least one initiator and (iv) at least one chain transfer agent; and at least one cellulose reactive agent; wherein the copolymer backbone and cellulose reactive agent are combined with water to form a solution wherein the concentration of the copolymer backbone is about 0.1 to about 19% by weight based on the total weight of the solution. A process to make high solids copolymer backbone with low molecular weight and narrow molecular weight distribution has also been developed by a continuous polymerization process under refluxing conditions. In this process, a mixture of the acrylamide, co-monomer and chain transfer agent and the initiator are simultaneously and continuously added to a heel of water.
    • 包含聚合物的组合物,所述聚合物是以下物质的反应产物:共聚物主链,包含: (i)至少一种丙烯酰胺组分,(ii)至少一种共聚单体,(iii)至少一种引发剂和(iv)至少一种链转移剂; 和至少一种纤维素反应剂; 其中所述共聚物主链和纤维素反应剂与水混合以形成溶液,其中基于溶液的总重量,共聚物主链的浓度为约0.1至约19重量%。 通过在回流条件下的连续聚合方法也开发了制备具有低分子量和窄分子量分布的高固含量共聚物主链的方法。 在该方法中,将丙烯酰胺,共聚单体和链转移剂与引发剂的混合物同时并连续地添加到水的后端。
