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.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
