Abstract: A potassium salt composition from seaweed, methods for producing the composition, and methods of using the composition of an essentially sodium-free salt substitute and/or potassium dietary supplement is described. The potassium salt composition has a pleasant salty taste and has a crystalline appearance that resembles regular table salt, but it is essentially free of the sodium and the metals. In addition, the product is essentially free of seaweed aromas or flavors which are removed by absorption or adsorption from an aqueous solution containing the dissolved potassium salt substitute.

Abstract: A liquid antifreeze which is produced from renewable resources, and which is biodegradable, non-toxic, and is non-corrosive to engines is provided. The liquid antifreeze composition for use as an engine coolant in a dilute or concentrate form comprises a water soluble salt of succinic acid, a water soluble salt of acetic acid, ethanol, and water, wherein the composition has a freezing point of greater than ?30° C. in the engine. A method for cooling an engine with a cooling system which comprises the coolant compositions is also provided.
