    摘要： The present invention provides a method of reducing chill haze in a protein containing liquid (especially beverages resulting from fermentation such as beer and wine) by contacting the liquid with silica microgels having an average microgel diameter of at least 18 nm, more preferably at least 45 nm, and most preferably at least 70 nm. It has now been discovered that microgels having an average microgel diameter of less than about 18 nm do not adequately reduce chill haze of a protein containing liquid. In particular, while microgels having an average microgel diameter of less than about 18 nm cause the coagulation of haze-forming components, these components remain suspended in liquid and continue to cause haze despite allowing the liquid to settle for long periods of time. Conversely, it has now been discovered that microgels having an average microgel diameter of at least about 18 nm cause the coagulation and precipitation of haze-forming components and the rapid settling thereof without the use of an organic polymer which acts as a flocculating agent.

    摘要翻译： 本发明提供了一种通过使液体与平均微凝胶直径为至少18nm，更优选至少为45nm的二氧化硅微凝胶相接触来降低含蛋白质液体（特别是啤酒和葡萄酒发酵产生的饮料）中的冷却雾度的方法 nm，最优选至少70nm。 现在已经发现，平均微凝胶直径小于约18nm的微凝胶不能充分降低含蛋白质液体的冷却雾度。 具体地说，虽然平均微凝胶直径小于约18nm的微凝胶导致雾化形成组分的凝结，但是这些组分保持悬浮在液体中并且继续引起雾度，尽管允许液体长时间沉降。 相反，现在已经发现，平均微粒凝胶直径至少约为18nm的微凝胶导致雾化形成组分的凝结和沉淀及其快速沉降，而不使用充当絮凝剂的有机聚合物。

    摘要： This invention relates to a process for converting silica to polysilicate gels or hydrogels by combining an aqueous silica source with a CO2 feed stream as the gel initiator, whereby the reaction stream is propelled at high velocity and turbulence maintaining the CO2 uptake rate in the reaction stream. The invention also relates to a process for converting silica to polysilicate by pre-carbonating water at pressures of equal to or greater than 100 psig before initiating the polysilicate reaction.

    摘要： A SOLUTION OF ALKALI METAL SILICATE IS PARTIALLY NEUTRALIZED WITH ABOUT 6% SULFURIC ACID TO ABOUT PH 10.6-10.9 STIRRED VIGOROUSLY AND COMPLETELY NEUTRALIZED WITH MORE SULFURIC ACID. AFTER NEUTRALIZATION IS COMPLETE, AMMONIA IS ADDED UNTIL A PH OF GREATER THAN 7 IS OBTAINED. THE THUS FORMED SLURRY IS THEN AGED AT ABOUT 80*C. FOR ABOUT 1 HOUR AND FILTERED. THE RESIDUE IS WASHED WITH ABOUT 0.1% AMMONIUM CARBONATE SOLUTION AT ABOUT 80*C. AND THE THUS WASHED SOLIDS ARE SIZED AND DRIED. THE RESULTANT SILICA GEL HAS A BULK DENSITY OF ABOUT 0.03-0.10 G./CC., AND A SURFACE AREA OF ABOUT 200-400 M.2/G.
