“…It is clear that the CKM predictions largely overestimate the glass transition temperature of both disaccharides all over the composition range, as already noted by Blond et al [96] for sucrose aqueous solutions.…”

“…They found an excellent agreement with the experimental results for glucose and fructose up to w 2 = 0.7, that is, well beyond the eutectic points. However, the results for sucrose using both models overestimate the freezing depression above w 2 = 0.7, as found by Blond et al [96], the predictions of the UNIFAC model being worse than those of the UNIQUAC (see Fig. 2) due to the fact that the latter one has temperature-dependent interaction parameters.…”

“…Blond et al [96] extended the calculation of the freezing curve for sucrose aqueous mixtures above the eutectic point (up to w 2 = 0.79) using UNIQUAC with the interactions parameters reported in Table 1 [17]. The results, shown in Fig.…”

“…2, indicate that above w 2 = 0.7, the predicted fusion temperature decreases are slightly larger than experimentally observed. The modification of the UNIQUAC parameters, including extra experimental data [96], worsens the deviation in the concentrated region.…”

This paper describes the main thermodynamic concepts related to the construction of supplemented phase (or state) diagrams (SPDs) for aqueous solutions containing vitrifying agents used in the cryo-and dehydro-preservation of natural (foods, seeds, etc.) and synthetic (pharmaceuticals) products. It also reviews the empirical and theoretical equations employed to predict equilibrium transitions (ice freezing, solute solubility) and non-equilibrium transitions (glass transition and the extrapolated freezing curve). The comparison with experimental results is restricted to carbohydrate aqueous solutions, because these are the most widely used cryoprotectant agents. The paper identifies the best standard procedure to determine the glass transition curve over the entire water-content scale, and how to determine the temperature and concentration of the maximally freeze-concentrated solution.

“…The phase transition temperatures were determined by the intersection of the baseline and tangent to the end of the endothermic peak of the DSC chart on heating. T g was determined as the temperatures corresponding to half of the magnitude of the heat capacity change (ΔC p ) at T g (Blond, G.;Simatos, D.;Catté, M.;Dussap, C. G.;Gros, J. B.…”
