Description
A hydrocolloid that creates heat-stable foams with unique texture-shifting properties.
Technical
Methylcellulose (E461) forms thermo-reversible gels—dissolving in cold water but gelling when heated (50-70°C). Foams are stabilized by interfacial film formation, with viscosity inversely proportional to temperature.
Culinary Significance
Enables aerated hot dishes like 'hot ice cream' or savory foams that retain structure at serving temperatures impossible for traditional foams.
