Yeast is a kind of microorganism that can survive under aerobic and anaerobic conditions. It is a natural catalyst. There are roughly three types of yeast, tea yeast, beer yeast, and flour yeast

1. Ordinary yeast

What we usually use is ordinary yeast. This kind of yeast is suitable for making steamed buns, flower rolls, steamed buns and other dough-making foods. The yeast needs to be heated when the water temperature is between 35℃ and 43℃. The yeast will be most active during the fermentation period, so when making leavened food, it is best to dissolve the yeast with water first, so that the yeast water can be fully integrated into the flour, and the dough will rise well.

The fermentation temperature cannot be lower than the freezing point of water, nor higher than 47 degrees. The most suitable temperature is generally 20-30°. The sugar tolerance of ordinary yeast cannot exceed 7, so when making pasta, do not add too much Polysaccharide, negative will inhibit the fermentation of yeast.

2. High-sugar-tolerant yeast

This high-sugar-tolerant and highly active yeast has a sugar tolerance of 30, so it is usually used to make bread, sweet toast, etc. Food, high-sugar-tolerant yeast has the characteristics of ordinary yeast, which means that high-sugar-tolerant yeast can be used to make steamed buns, rolls and other dough-making foods.

In my personal opinion, it is usually more convenient to use high-sugar-tolerant yeast, because when using an automatic bread machine to make bread, other auxiliary ingredients can be added before the flour is fermented. In this way, the effect of using ordinary yeast is not as good as using high-sugar-tolerant yeast. Fermentation, but high sugar tolerance yeast is slightly more expensive. Of course, making steamed buns does not necessarily require the fermentation raw material formula provided by the "bread machine".

There are also particularities in adding yeast when making steamed buns, so it is better to tolerate high sugar. Although the price is a bit more expensive, the steamed buns will definitely be delicious. Who would refuse to eat it? I eat steamed buns, I hope my answer is helpful to you!
