Why is lime added to tortillas?

Dear Joel: It’s chemical lime. Why is it used? Because treating corn with slaked lime (calcium hydroxide, commonly known as “cal”) helps to remove the corn hulls in processing. And incidentally, the cal makes the niacin more nutritionally available and the corn easier to digest.

Why is lime used in masa?

To make masa harina, field corn (or maize) is dried and then treated in a solution of lime and water, also called slaked lime. This loosens the hulls from the kernels and softens the corn. In addition, the lime reacts with the corn so that the nutrient niacin can be assimilated by the digestive tract.

How corn is treated before it is made into tortillas?

Nixtamalization spread with corn culture to the American southwest, where nixtamal is known by the native American word hominy, and potassium carbonate (potash) and lye are the common bases. Nixtamalized corn makes a fantastic masa –ideal for tortillas, tamales, tlacoyos, etc.

How do you Nixtamalize corn with lime?

In a medium pot, combine corn and water; pick out any stones that may be hiding among the corn kernels. Add pickling lime and set over medium heat. Bring to a simmer, adjusting heat to maintain simmer. Cook until corn is tenderized but not overly soft, about 45 minutes.

Why is corn soaked in calcium hydroxide?

The dry corn is brought to a near boil and then left to soak overnight in hot water with an added dose of cal—calcium hydroxide, also known as slaked lime or pickling lime. This breaks the CaCO3 into carbon dioxide and calcium oxide. Adding water to the calcium oxide—“slaking” it—creates calcium hydroxide.

Why are tortillas an important ingredient in the Mexican diet?

Tortillas are the quintessential staple food of the Mexican diet and cuisine. Maiz or corn Tlaolli was considered a sacred plant, the most important staple food of both past and present-day Mexicans. Tortillas were originally made with corn, not flour.
