Description
Instantaneous starch gelatinization and protein denaturation creates porous, crispy shrimp crackers.
Technical
Rapid vaporization of residual moisture (2-5% water content) causes explosive puffing of pre-gelatinized starch matrix. Maillard reactions on surface proteins generate umami compounds.
Culinary Significance
Transforms dense tapioca-shrimp pellets into light, airy crackers with audible snap.
