Nixtamilization is the process of breaking down maize's pericarp (hard outer
covering) by soaking the kernels in water with lime (traditionally wood ash).
This makes a dough (masa) more easily converted into tortillas and adds a
particular flavor. In addition, the lime also releases the niacin in the corn,
thus creating a more nutritious food (and preventing pellagra caused by niacin
deficiency).

Therefore, nixtamilized corn is corn that ha gone through this process.

PS I've already recommended that the word be added to the OED.
