The gelatinization of wheat starch influences the final structure and texture of baked goods. Sucrose effectively elevates the gelatinization temperature (Tgel) of starch more than many sweeteners, and maintaining a higher Tgel has been a challenge while reducing the amount of sucrose in baked goods. The objective of this study was to quantify the effects of 14 different oligosaccharides (OS: maltose, isomaltulose, kestose, maltotriose, melezitose, raffinose, stachyose, a fructo-OS, a galacto-OS, an isomalto-OS, lactosucrose, a xylo-OS, and two glucose-based dextrins), allulose, and sucrose at different concentrations (0 to 60% w/w) on the Tgel of wheat starch using DSC, and to determine which OS physicochemical properties best explained the Tgel results. OS type and concentration significantly altered Tgel. Many OS elevated the Tgel as much as or more than sucrose at the same solution concentrations, while allulose did not. The onset T...
