Alginates

Propylene glycol alginate (no relation to the propylene glycol found in antifreeze) (A)

Propylene glycol alginate acts as a thickener, stabilizes emulsions and foams, lends a creamy mouthfeel to sauces, and forms clear gels. It forms an even stronger gel when used with sugar. Like many hydrocolloids, it resists syneresis—the weeping out of liquid from colloids such as vegetable purées. It hydrates at any temperature, with stirring, in about 5 minutes. It is typically used in concentrations of 0.4% to 1%.
