Calcium hydroxide is a calcium-containing compound also known as slaked lime and pickling lime. It is used primarily to regulate acidity, to maintain firmness in pickled foods, and as a source of calcium.
Calcium hydroxide has shown no negative effects in the amounts present in food. It is easily dealt with by normal metabolism and is a usable source of calcium. It has a low toxicity and is mild in the quantities present in food.
Purchase and use of calcium hydroxide powder carries risks when improperly used. Commercially produced foods using calcium hydroxide ensure safe pH levels (alkalinity).
