Can the egg beater be used to froth milk?

It is not recommended to use an egg beater to froth milk

First of all, our home egg beaters are divided into two types, manual egg beaters and electric egg beaters. The manual egg beater cannot achieve uniform and concentrated rotation during the beating process. The milk produced in this way will only produce large bubbles on the surface. At the same time, the butterfat content of fresh milk is less than that of cream, so it is impossible to mix it at low temperatures. The combination of fat and air produces a thick state, and the milk protein in the milk cannot be whipped in hot milk to produce stable foam, so a manual egg beater cannot froth the milk used in hot latte.

After talking about the manual egg beater, let’s talk about the electric egg beater. The selection speed of the electric egg beater can be said to be very slow, and the whipping head of the electric egg beater is also very large. If you put the milk in a large container, no matter how much it contains, there will not be enough milk fat to create resistance. , as soon as the egg beater is turned on, you will get a "all over" scene.

So why can the steam wand method of beating milk produce dense milk foam?

The steam wand method is to use steam to beat the milk, so that the liquid milk is blown into the air, and the surface tension of the milk protein is used to form many small foams, which expands the volume of the liquid milk and becomes Foamy milk foam. During the foaming process, lactose dissolves in the milk due to the increase in temperature, and uses the foaming effect to seal the lactose in the milk. The function of the milk fat is to make these small foams form a stable state, making these milk bubbles When drinking, the fine foam will burst in the mouth, allowing the taste and aromatic substances to be better dispersed and amplified, giving the milk a sweet and thick taste and texture.
