Description
Alkaline treatment of corn masa with wood ash increases protein network formation through pH-induced structural changes.
Technical
Wood ash (primarily potassium carbonate) raises pH to 8-10, inducing partial hydrolysis of corn proteins (zeins) and starch gelatinization at lower temperatures. This creates a more cohesive protein-starch matrix through disulfide bond rearrangement.
Culinary Significance
Produces a uniquely elastic texture compared to untreated corn dough, allowing for better structural integrity in steamed preparations.
