1, enhance the ductility and plasticity of dough
Butter has good emulsification. Kneading softened butter into dough can lock the moisture in dough, change the wet viscosity of dough and enhance the ductility of dough. The dough with good ductility will have a better expansion rate after entering the furnace, and the bread made will be fluffy and soft.
2, the aroma is increased during baking, and the color is more beautiful.
Butter contains protein, amino acids and a small amount of sugar, which can produce Maillard reaction when heated (it is the reaction between reducing sugars and amino compounds, and finally produces melanoidin after a complicated process. Besides melanoidin, the reaction also produces reducing ketones, aldehydes and heterocyclic compounds, which are the main sources of food color and flavor. ), while coloring the bread, it releases the sweet smell of soft bread.
3. It can delay the aging process of bread
After the bread is baked, the internal water will slowly vaporize. In the process of water evaporation, the starch changes due to aging, which is the aging process of bread. Bread with oil can prevent the evaporation of water and emulsify the free water in bread to some extent, so as to lock in the water and delay the process of starch aging and bread hardening.
After talking about the role of butter in bread, let's look at the difference between bread made of vegetable oil and bread made of butter.
Adding vegetable oil to the dough, the extensibility of the dough is not as good as that of the dough added with butter, so the bread made from vegetable oil is slightly worse in bulkiness and less fragrant in taste, but the calories of the bread made from vegetable oil are relatively low. Vegetable oil is a good choice for people who want to lose weight and eat bread. When choosing vegetable oil, it is best to use oil with no obvious smell, so that it will not have a strange smell and will not cover up the taste of the food itself.
You don't have to use butter when making bread, but you can use vegetable oil. There are mainly these differences. After reading it, is it clear in your heart? When you make bread, you can try to make it with these two oils respectively and make a comparison by yourself, so that you can understand it more deeply.
