Speaking at an Institution of Chemical Engineers’ (IChemE) lecture, Professor Grant Campbell said that bubbles in bread are as important for making a good sandwich as its filling, due to the unique composition of wheat.
“Bread is special because of its bubbles. It’s got these bubbles because wheat, when mixed with water, salt and yeast is the only cereal that can trap the carbon dioxide and give us raised bread.
“That raised bread makes for soft bread and it’s soft because of the bubbles. Different breads are distinguished by different aerated structures. It’s one of the reasons why brown or wholemeal bread is less suitable for making tasty sandwiches – the bran pops the bubbles.
“Chemical engineers are working to find a way of getting bran into bread recipes without popping the bubbles. By doing this we will create a healthier bread without sacrificing the tastiness. Nutritionists have been telling us to eat more wholemeal bread for decades but we still prefer white bread because it tastes better” explained Campbell.
Speaking at Birmingham University to an audience of chemical engineers, scientists and students, Campbell was awarded IChemE’s Frank Morton medal – recognising his outstanding service to chemical engineering education.
“Bubbles have made wheat the world’s most important food crop. If you took all the engineers that have ever lived and asked them to recreate such an appealing food structure, at such a price that most people in the world could afford to eat it every day, they wouldn’t come up with anything as remarkable as bread,” said Campbell.
“Bread is the world’s most important food and wheat is the king of grains because of its unique ability to give us bubbly bread,” he concluded.
Campbell, based at the University of Manchester, also explained the key role bubbles play in other foods and drinks, including chocolate, champagne and meringue.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
