ResumoThis paper reviews recent progress in the study of gelatin gels. For example, it is now established that gel junction zones do not have a large cross-sectional radius of gyration, and both the modulus and the absolute optical rotation appear to increase slowly, but without limit, even when plotted on a log time axis. Such data are not consistent with substantial side-by-side aggregation following the initial renaturation of the collagen-like triple helix. The rheological consequences of this are discussed. At very low concentrations, atypical effects are seen, indicating the existence of a transient weak network.
