With the development of industry and science and technology, the biscuit industry has formed a modern industrial production system. No matter biscuit or sandwich biscuit, the biscuit production line can not do without these "three raw materials": wheat flour, oil and filling agent. Let's see:
1. Wheat flour
Nowadays, wheat flour used for biscuits is no longer added with dough improver to improve its performance, but mainly added with natural gluten. The main consideration is to use dough improver to pollute food. At present, foreign countries use air classifier for wheat flour, which can distinguish different protein content and flour fineness. Then prepare biscuit powder, bread powder, cake powder and noodle powder according to the quality requirements of wheat flour baking products to ensure the stability of biscuit quality. But the fundamental problem is that agricultural researchers attach great importance to the improvement of wheat varieties, and long-term breeding research and cultivation have successfully adapted to various special wheat varieties.
2. Grease
Vegetable shortening has been used in the production of biscuits, which is beneficial to the looseness and stability of biscuits. At present, there are many kinds and specifications of shortening used to make cookies in the world. In addition to conventional plastic block shortening and powder shortening, in order to meet the needs of industrial automation and large-scale pipeline production of biscuit production lines, grain and oil researchers also invented liquid biscuit shortening suitable for the requirements. Biscuit industry.
3. Loosening agent
In addition to traditional biscuit loosening agents, sodium bicarbonate and ammonium bicarbonate, most biscuit production lines also use compound chemical loosening agents, such as sodium bicarbonate and acid salts. The biscuit becomes crisp and the residue in the food is non-toxic.
