1, baking

Baking refers to the process of making cakes, bread, cakes, biscuits, cakes and other foods in an oven or similar equipment by using hot air or radiation heating. Baking can promote the internal expansion and discoloration of food, and make the surface of food form a crisp shell.

The baking process includes a series of chemical and physical reactions. When food enters the oven, hot air or heat radiation will transfer heat to the food surface, and the water on the food surface will evaporate to form steam, which will expand the food.

At the same time, starch in batter will undergo gelatinization reaction, protein will solidify, and yeast or chemical starter will produce carbon dioxide, which will further promote food expansion. During the baking process, the inside of food will become dry and remain soft.

The temperature and time of baking depend on the kind and size of food. Different recipes and ingredients need different baking conditions to ensure that the food is mature and presents the ideal taste and appearance.

In the baking process, some insulation tools are usually used, such as baking molds, baking trays, baking paper, etc., to help evenly transfer heat and prevent food from sticking.

Baking is a widely used method in food production, which can make all kinds of delicious cakes, cakes and sweets. Whether it is home baking or professional baking, you need to master baking skills and recipes, and have a certain understanding of the characteristics of temperature, time and ingredients in order to obtain the best baking effect.
