, which is ground into a relatively dry dough to create fresh masa. The fresh masa can be sold or used directly, or can be dehydrated and blended into a powder to create masa harina, or masa flour. Lime and ash are highly alkaline: the alkalinity helps the dissolution of hemicellulose, the major glue-like component of the maize cell walls, and loosens the hulls from the kernels and softens the corn. Some of the corn oil is broken down into emulsifying agents (monoglycerides and diglycerides), while bonding of the corn proteins to each other is also facilitated. The divalent calcium in lime acts as a cross-linking agent for protein and polysaccharide acidic side chains. The chemical changes in masa allow dough formation, and also allow the nutrient
