Description

Calcium lactate is a calcium salt formed when lactic acid binds with calcium. It appears as a white, nearly odorless powder that dissolves in water and contains about 13% elemental calcium by weight. You’ll encounter it as a food additive (listed as E327 in Europe), a dietary supplement, and an ingredient in food preservation, dental products, and molecular gastronomy. Despite the name, it has no connection to lactose or dairy.
