Description
Sulfated polysaccharide from red seaweed that forms thermo-reversible gels to structurally support comminuted meats.
Technical
Lambda-carrageenan's sulfate ester groups (-OSO₃⁻) interact electrostatically with meat proteins while helical conformations entrap water molecules through hydrogen bonding. This dual mechanism (Coulombic attraction + physical entrapment) prevents purge loss during thermal processing.
Culinary Significance
Enables juicier texture in low-fat formulations while maintaining slice integrity in deli meats and preventing casing blowouts in frankfurters.
