Description
Sushi rolling is a mechanical technique that compacts vinegared rice and fillings into a cohesive cylinder using controlled pressure and temperature.
Technical
The process relies on the gelatinization of rice starch at 30–35 °C, followed by acid‑induced retrogradation from vinegar, which imparts stickiness and firmness. Precise pressure application prevents starch granule rupture while maintaining structural integrity.
