Comparing Wheat Gluten With Corn (Zea) Glutens

Corn is prepared for breading by boiling in water with alkali, resulting in a de-skinned material called nixtamalized masa. Masa can be used for industrial purposes (tortillas, tamales, chips), but it must be used quickly because its glutens change rapidly and binding decreases rapidly. Masa does not store well and chemicals are added to enhance preservation at the expense of quality. At its peak attempting to use masa as dough generally results in a crumbly flat bread, correctable by regrinding masa to a fine flour and adding gums (such as Xanthan Gum). In contrast the glutens in wheat have more adhesive properties that change when prepared in different ways. The glutenins, for example, stretch, but can also fix their shape at high temperatures, causing bread to maintain its characteristic rise.

    Charles Krauthammer (b. 1950)

    Another success is the post-office, with its educating energy augmented by cheapness and guarded by a certain religious sentiment in mankind; so that the power of a wafer or a drop of wax or gluten to guard a letter, as it flies over sea over land and comes to its address as if a battalion of artillery brought it, I look upon as a fine meter of civilization.
    Ralph Waldo Emerson (1803–1882)

    Editor: a person employed by a newspaper, whose business it is to separate the wheat from the chaff, and to see that the chaff is printed.
    Elbert Hubbard (1856–1915)
