We review some recent experimental results on physical gels made of biopolymers which are either vegetal (pectin, agarose) or animal (gelatin). These are either neutral (agarose) or electrically charged (pectin, gelatin). Two types of gels are considered:
  • Thermoreversible gels, stabilized by secondary links and/or pseudo crystallization of multiple helices. There is usually hysteresis when cooling the system down or heating it up. For both gelatin and K-carraghenan, it is shown that gelation occurs in two successive stages corresponding to two helicoidal distributions whose relative importance depends on time.

  • Ionic gels that are formed by selective fixing of bivalent ions such as calcium with the “egg-box” mechanism (pectin). The importance of the microstructure (a random sequential distribution of carboxylic groups) is analyzed. With light scattering and viscosity measurements we show the influence of charge density on gel formation.
