Understanding functionality of sucrose in cake for reformulation purposes

Area of Science:

• Food Science
• Material Science

Background:

• Sucrose provides sweetness and crucial structural functionalities in cake manufacturing.
• Reformulated cakes require sugar replacers that mimic sucrose's functional properties.

Purpose of the Study:

• To review sucrose functionality in cake manufacturing from a sugar replacement perspective.
• To understand how to achieve similar cake textures with sugar replacers.

Main Methods:

• Utilizing Complex Dispersed Systems methodology to summarize cake structure and texture development hypotheses.
• Employing a supplemented state diagram to represent phase transitions during baking.
• Applying physical theories to characterize plasticizing and hygroscopic behaviors of sugars and replacers.

Main Results:

• Sucrose acts as a plasticizer and humectant, influencing biopolymer phase transitions, dough viscosity, and water activity.
• Starch gelatinization and egg white denaturation can be predicted by the volumetric density of hydrogen bonds in the solvent (water, sugar, or replacers).

Conclusions:

• Successful sugar replacement in cakes hinges on mimicking sucrose's plasticizing and humectant properties.
• Understanding hydrogen bond density provides a theoretical basis for predicting key baking transitions with sugar replacers.
