And the article contained the following:
The effect of sugars and sugar replacers (i.e. plasticizers) on the gelatinization and pasting behavior of wheat starch was studied. The intrinsic properties of the plasticizers, i.e. the molar volume d. of effective hydroxyl groups NOH,s/vs, and the volumetric d. of hydrogen bonds in the sugar solutions treated as a single solvent, i.e. Φw,eff, were proposed as factors controlling swelling (i.e. pasting) and gelatinization behavior. Different classes of plasticizers were used including sugars, polyols, amino acids, soluble fibers such as oligofructoses, and mixtures thereof. The onset, peak and end temperature of starch gelatinization obtained by differential scanning calorimetry could be well described by Φw,eff for all solutions, following predictions from an adapted Flory-Huggins model for polymer melting. The multiple transitions involved in starch gelatinization could be well related to different ranges of Φw,eff following a side chain liquid crystalline model for starch. Deviations from the model predictions were observed mainly for Tonset in conditions of intermediate and excess solvent with high sugar concentrations (50% weight/weight). In such conditions phase separation likely occurs, increasing the effective starch concentration and consequently gelatinization temperatures Pasting behavior related to swelling, i.e. peak viscosity, was found to be a sigmoidal Fermi function of NOH,s/vs of the plasticizers. Plasticizers with high NOH,s/vs enhanced swelling compared to water while those with low NOH,s/vs had an inhibition effect. Overall, a comprehensive mechanism of starch plasticization, swelling and melting is proposed. Swelling associated with solvent ingress and helix-helix dissociation is affected by kinetic factors related to size and viscosity of the plasticizers (both described by NOH,s/vs) and by thermodn. factors related to sugar partitioning and H-bonding ability (both related to Φw,eff). Melting of crystalline domains associated to helix-coil transition is controlled by thermodn., based on solvent H-bonding ability Φw,eff. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Recommanded Product: 585-88-6
