From the point of view of human health, yeast powder is beneficial and harmless to our human body, but yeast powder is not necessarily. Baking powder is a kind of chemical initiator, which can be divided into two categories according to its composition. One is alkaline. The main components of this baking powder are sodium bicarbonate and ammonium bicarbonate, which are generally harmless to human body.

However, there is another kind of baking powder which is compound, and its main components are alum and ammonium alum. Alum contains aluminum, which is easy to cause Alzheimer's disease, osteoporosis and some cardiovascular diseases. It is unhealthy, and the aluminum salt used by some unscrupulous merchants will cause brain cells to atrophy and die. Therefore, friends who often eat buns, steamed buns, cakes and other cakes outside should pay attention. Some unscrupulous merchants may use compound baking powder in order to ferment cakes quickly.

Characteristics of yeast powder fermentation;

A large number of microorganisms in yeast powder can decompose maltose, glucose and so on. , thus releasing carbon dioxide gas, resulting in countless holes in the dough. When baked or steamed, it can soften cakes. It has the same effect as baking powder, but it doesn't rise as fast as baking powder, and it also needs the cooperation of temperature and humidity. These are some minor shortcomings.

The biggest disadvantage of yeast powder is that its fermentation effect is unstable and easily influenced by external temperature and humidity, but it also has its obvious advantages, that is, the pasta fermented by yeast powder has unique flavor and high nutritional value, which is very suitable for family use.
