What it is

Water and lime refers to a mixture of water and calcium hydroxide (slaked lime). Calcium hydroxide is a white powder made from heating limestone. It is used to treat corn kernels in a process called nixtamalization.

Why it's used

Manufacturers use water and lime primarily for nixtamalization, a process that makes corn more nutritious and easier to grind into masa for tortillas and tamales. It also improves the texture and flavor of corn-based products.

Health notes

In the U.S., calcium hydroxide is Generally Recognized As Safe (GRAS) by the FDA for use in food. Nixtamalization significantly increases the availability of niacin, a B vitamin, in corn, helping to prevent pellagra. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated calcium hydroxide and established an acceptable daily intake.

Allergen info

Water and lime is not derived from any of the 9 FDA major allergens. It does not contain gluten.
