The effect of ageing at 4 degrees on the viscoelastic properties of 1-5 and 2-0% acid and alkaline processed gelatin gels has been investigated. Viscoelastic properties were not markedly affected by ageing time although evidence of a decrease in gel structure with increasing ageing time was apparent. This has been tentatively attributed to hydrolysis of amide links. 1-5% alkaline gels were shown to be more rigid than the corresponding acid gels and this has been discussed in terms of differences in molecular weight, polydispersity, charge and charge distribution.
