Nixtamalization is a traditional process used to prepare corn kernels for further processing into tortillas and other corn-based products. The process involves soaking corn kernels in a solution of lime (calcium hydroxide) and water, followed by cooking and rinsing. This technique has been used by indigenous peoples in Mesoamerica for thousands of years and is a key step in the production of maize-based foods.

The primary purpose of nixtamalization is to alter the corn's physical and chemical properties, making it more digestible and easier to grind into a fine flour. The lime solution causes the corn kernels to swell, which helps to break down the tough outer layers and expose the starch inside. During the cooking process, the lime reacts with the corn's proteins, forming a complex called phytate, which binds to minerals and makes them less available for absorption. This process also denatures the proteins, making them easier to digest.

After cooking, the corn is rinsed to remove the lime and any remaining phytate. The resulting product, known as nixtamal, is then ground into a flour called masa, which can be used to make tortillas, tamales, and other traditional dishes. Nixtamalization is a crucial step in the production of many traditional Mexican and Central American foods, and it plays a significant role in the cultural and culinary heritage of these regions.
