Method for producing sponge cake
Technical Field
The invention relates to a method for producing sponge cakes, and belongs to the technical field of food processing.
Background
Baked goods are the mainstream food in the world, and cake products play a significant role in baked goods. The sponge cake is a popular one of cake products, has good taste and flavor, attractive color and wide market prospect.
However, the sponge cake is easy to age in the storage process, so that the quality of the sponge cake such as taste after being stored for a period of time is greatly reduced, and the shelf life of the sponge cake is further reduced.
Attempts have also been made to increase the shelf life of sponge cakes by increasing the moisture content of the sponge cake to slow the aging process of the sponge cake during storage. However, the moisture content makes the sponge cake easily deteriorate, and the object of increasing the shelf life of the sponge cake cannot be achieved per se. In addition, the quality such as taste and mouthfeel of the sponge cake can be influenced by overhigh moisture content, and the purchase desire of consumers is greatly reduced.
Therefore, a method for improving the storage performance of the sponge cake and ensuring the quality of the sponge cake such as taste and mouthfeel is urgently needed to be found so as to solve the defects of the existing sponge cake.
