What You Need to Know
Involves gelation of agarose polymers at ~45°C followed by controlled dehydration to preserve porous matrix structure, then mechanical grinding to specific particle sizes (typically 50-200µm).
Enables rapid texture modification without heating, allowing chefs to create instant gels, foams, or thickeners with precise control.
