For a moist cake

cake
Originally a basic staple, cereal products have developed into pleasure foods that are now part of our daily meals. In this context, the textural properties of pleasure foods such as cake strongly influence the consumer’s choice.

Using a multi-scale approach, from the macroscopic to the molecular level using increasingly complex model systems, our work has linked this texture to the interactions between the ingredients during baking, to water availability and to storage conditions.

During the actual baking of the batter, the interactions between the ingredients control the temperature of starch gelatinization and protein denaturation. These phase transitions take place at higher temperatures in the presence of sugar, which controls the availability of water in a lowly hydrated system such as cake batter. Their role is fundamental to explain the batter-crumb transition.

Finally, the study of the effect of storage temperature during the staling process reveals a better conservation of cakes at 4°C, in contrast to the literature where it is shown that the staling of bread increases during storage at low temperatures.
