Xylitol, mannitol and maltitol as potential sucrose replacers in burger buns


Burger buns are a source of added sugar, containing 7-12%, in order to ensure their unique texture and taste. Hence, suitable sugar substitutes for burger buns are urgently needed. This study aimed to elucidate the effect of three different polyols on dough and product quality of burger buns. Xylitol, mannitol and maltitol were incorporated individually in a burger bun system, by replacing added sucrose by 30%, 50% and 100%. Wheat starch was used to compare the impact of polyols with another non-sweet bulking agent. The effects on dough properties as well as on the burger buns themselves were investigated. Compared to sugar-rich doughs, polyols lowered the fermentation quality, resulting in lower dough development (-37 to -81%) and poorer gaseous release (-62 to -87%). Furthermore, a delay in gluten network development (+50 to +161%) and a decrease in extensibility (-14 to -18%) with increasing concentrations were detected. Interestingly, maltitol and xylitol did not affect the pasting properties, whereas mannitol increased pasting temperature (+15 °C). Moreover, polyols did not influence the viscoelastic properties of the dough. The incorporation of sugar alcohols led to a significant decrease in specific volume (-30 to -48%), and to a harder crumb texture (+135 to +678%). Moreover, the L*-value increased with increasing amount of polyols, resulting in a very pale crust colour. As a conclusion, a reduction of 50% added sucrose by polyols was applicable, whereas mannitol was the most suitable sugar replacer amongst the polyols tested.
