This product is an acid salt and is generally not used alone. It is often mixed with sodium pyroate (alkaline salt, which has a specific effect with protein in meat and can significantly enhance the water holding capacity of meat). This product reacts with sodium bicarbonate to produce carbon dioxide, which can be used as raw material for rapid fermentation powder.
