Is baking powder harmful to human body?

Ordinary baking powder is harmless, but some alum and aluminum salt baking powder are harmful.

Generally speaking, baking powder is harmless to our health. After all, it is a very necessary material for making cakes. Although it contains chemicals such as baking soda, it is harmless to our health and widely used.

But there is a kind of baking powder that may cause harm to the body, that is, baking powder with alum and aluminum salt added in it. This kind of baking powder hardly needs to wait for the dough to be ready soon, so it is very popular with merchants, but the aluminum contained in it is a great health challenge.

Because aluminum itself is harmful to human body, the state has strict regulations on its intake in food. Excessive intake of aluminum may damage brain cells and cause Alzheimer's disease, cardiovascular disease, osteoporosis and other diseases. Therefore, when buying baking powder, you should look for "aluminum-free baking powder" and eat it often.

Making principle of baking powder;

Baking powder is a kind of white powder, which contains acid substances such as baking soda powder and corn flour as filler. When baking powder meets water, acidic powder and alkaline powder are dissolved in water at the same time to react, and some of them will start to release carbon dioxide (CO). At the same time, in the process of baking and heating, more gas will be released, which will make the product expand and soften.

Fast-reaction baking powder starts to work only when it is dissolved in water, while slow-reaction baking powder starts to work during baking and heating. Among them, the double reaction baking powder has the reaction characteristics of fast and slow baking powder. The baking powder purchased in the market is generally "double reaction baking powder".

Although baking powder contains baking soda powder, acid powder (such as Tata powder) is added after precise detection to balance its pH value. So basically, although baking powder is alkaline, baking powder on the market is neutral. Therefore, baking powder and baking powder cannot be replaced at will.

As a filler in baking powder, corn flour is mainly used to separate acidic powder and alkaline powder in baking powder to avoid their premature reaction. Baking powder should also be preserved as much as possible to avoid premature failure due to moisture.
