<unk>  is a white crystalline salt made by the action of lactic acid on<unk>  carbonate. It is used in foods (as a baking powder) and given medicinally. Its E number is E327.<unk>  is often found in aged cheeses.  Small crystals of it precipitate out when lactic acid is converted into a less soluble form by the bacteria active during the ripening process.
In medicine,<unk>  is most commonly used as an antacid and also to treat<unk>  deficiencies.<unk>  can be absorbed at various pHs and does not need to be taken with food for absorption for these reasons.<unk>  is added to sugar-free foods to prevent tooth decay. When added to chewing gum containing xylitol, it increases the remineralization of tooth enamel. It is also added to fresh-cut fruits such as cantaloupes to keep them firm and extend their shelf life, without the bitter taste caused by<unk>  chloride, which can also be used for this purpose.
