  • Beverage thickener emulsifier system
    Patent number: 5385748
    Abstract: This invention relates to a beverage thickener/emulsifier system which is a blend of three materials: propylene glycol alginate (a surface active thickener), xanthan (a pseudoplastic thickener) and guar gum (a Newtonian thickener). This system provides very stable oil-in-water emulsions in beverages and provides full bodied beverage texture even at acid pH. The system uses a low total gum level (below 0.4% in a single strength beverage) yet provides a very stable oil emulsion without excessive thickness.
