Abstract

Amorphous silica can be prepared in a stable and pumpable suspension, suitable for use in alcoholic beverage stabilisation, by adding a polysaccharide or inorganic gelling agent. Examples of polysaccharides are carboxy methyl celluloses, guar gum and Xanthan gum. Preferably the suspension contains sorbic acid, benzoic acid or a benzoate to give synergistic action with the polysaccharide.
