I. Introduction

Baking, also known as baking, refers to the process of dehydration, drying and hardening of materials through dry heat under the ignition point of materials. Baking is an indispensable step in the production of bread and cake. After baking, starch undergoes a series of chemical changes such as gelatinization and protein denaturation, which makes bread and cake mature. It can also change the taste of food;

Second, the nutritional value

1, the baked goods that people like to eat are rich in nutrition, not to mention that most baked goods are suitable for adding various nutritious food raw materials. As far as wheat flour is concerned, it has incomparable nutritional advantages over other grains;

2. The protein content of wheat flour is 2-3 times that of rice and 2 times that of corn flour, especially its calcium content is 4 times that of rice and 8 times that of corn flour. The contents of VB 1, VB2 and nicotinic acid in wheat flour are all 3 ~ 4 times that of rice.

3. In addition, due to the physical and chemical effects of yeast, baked food is rich in protein and amino acids, easy to absorb, and good in taste and color. Therefore, in western countries, bread of baked goods has almost become synonymous with food and grain;

4. Baked food is not only nutritious, but also has incomparable processing advantages compared with other foods. The unique gluten component of wheat flour makes baked goods not only be processed into various forms, but also have various patterns and styles.

5. It has become the most influential industrialized staple food since human beings entered the industrialization era because of its operability in processing, swelling, preservation of finished products and convenience in eating;

Third, the important position.

Compared with other countries in the world, there is still a considerable gap in baked goods in China. There is still a lot of work to be done in processing technology, finished product quality, production scale and variety. In particular, the baked goods in China did not play its due role in the national economy and did not have a great impact on the modernization of people's diet.
