28 Oct'2011 Bread Making Technology

This day we had a teacher from the number 1 agricultural university in China, China Agricultural University, Prof. LIANG Jianfen. We had a great time I can tell you that. Her lecture was very systematic; she knows what to tell and what not to tell. 

These were bold points I learned today:
What is the different between bread and Chinese steamed bun (incl. noodles, dumplings, mantou, baozi)?
First, the flour used. In bread, hard wheat flour is used, while in Chinese steamed bun, medium wheat flour is used. 
Second, bread is baked while Chinese wheat products are usually steamed.

- Hard wheat VS. soft wheat
In a hard wheat structure the starch granules are coated with continuous film of protein, while in soft wheat structure the protein doesn't cover starch granules in continuous matrix.

-GSE
I know some people are sensitive to gluten due to celiac disease. They are also called GSE (gluten sensitive enteropathy). Is there any gluten-free bread company in China? According to the professor, NO, because GSE are rarely found in China.

-The amount of water added to dough is important
47% of water is not enough to bind the starch & formation of gluten, resulting in unbound matrix.
50-53% of water is just enough, continuous network is formed and optimum for gas trapping.
56% of water is too much, dough will have many holes and weaker bond.

- Frozen Dough Technology

At the end of the day we joined the opening party of the other batch of training. They were just come to Beijing for Food Biotechnology training for two months. They have more participants than us; most of them are from Africa and South East Asia. Great time!
