Sponge cake is a type of light, airy cake that is baked with flour and filled with a lot of air due to the foaming properties of the protein.

During the cake-making process, the protein is stirred at high speed to reduce the surface tension of the globulin, which increases the viscosity of the protein. Because of the large viscosity of the ingredients to help the formation of the initial foam, it quickly into the air, the formation of foam. The globulins and other proteins in the egg white are slightly denatured by the mechanical action of agitation.

The denatured protein molecules can condense into a layer, forming a very strong film that encloses the mixed air. At the same time, surface tension causes the protein foam to contract and become spherical.

The protein colloid has viscosity and the added flour material adheres to the protein foam, making the foam very stable. It keeps the gas in. In the process of heating, the gas inside the foam is heated and expanded. Make the product porous and loose and have certain elasticity and toughness.
