This paper presents the results of rheological measurements of solutions of gelatin in the transition zone preceding the gel temperature. The relaxation function G(t) proposed by Martin, Adolf, and Wilcoxon [Phys. Rev. A 39, 1325 (1989)] leads to very good agreement between the experimental data [η′(ω) and η″(ω)] and the calculated curves. The gel strength and characteristic time are determined as a function of temperature. © 1996 The American Physical Society.
