What You Need to Know
Thermoreversible gelation occurs when a mixture of gelatin and a solute is heated above its gelation temperature, causing the gelatin to unwind and form a sol. The sol then cools and gels upon reaching a temperature below its gelation point, resulting in a firm, jelly-like texture. Rheological measurements can be used to determine the optimal temperature and concentration of gelatin for a specific application.
