There are many ways to make dough, such as baking soda dough and yeast dough. These methods have the same effect, but their principles are different. In the former method, it is a chemical process. Baking soda will seriously destroy the B vitamins in flour. Yeast fermentation is completed through the biological process of yeast fermentation, which improves the nutritional value.
Yeast is divided into fresh yeast and dry yeast. It is an edible and nutrient-rich single-celled microorganism, which is called "inexhaustible nutrient source" in nutrition. Besides protein, carbohydrates and lipids, yeast is also rich in vitamins, minerals and enzymes.

Edible function of yeast
Dry yeast powder or granular products, which have no fermentation and reproduction ability, are for human consumption. It can be obtained by recycling yeast mud from brewery, or it can be specially cultivated and dried according to the requirements of human nutrition. The United States, Japan and some European countries add about 5% edible yeast powder to common foods such as bread, cakes, biscuits and scones to improve the nutritional value of food.
Yeast autolysate can be used as an additive for meat, jam, soup, cheese, bread, vegetables and condiments. It is used as a food nutrition enhancer in baby food and health food. The 5'- nucleotide prepared from yeast autolysis extract can be used as an additive in combination with monosodium glutamate to enhance the flavor of food.
The concentrated invertase extracted from yeast is used as liquefier for chocolate with square eggs. Extracting lactase from yeast produced in whey can be used to increase sweetness in milk processing, prevent lactose crystallization in whey concentrated solution, and meet the needs of lactose intolerant consumers.
